# "Believers Also Leg Day": a small Brazilian team used AI to turn 150 Psalms into workout trap tracks, packaged in an app sold for R$37.90 a year

**What it is** A music app for Christian fitness fans that uses AI to turn the Psalms into rap, trap, and drill, with playlists sorted by training intensity.

**Why it took off** It hits the identity pain point of "gym music doesn't fit my faith, and hymns are too slow." It then sells the low-priced ticket through Instagram reels, fitness creators, and long Hotmart landing pages; AI keeps the cost of the catalog close to zero.

**B** **How you could follow it** Stop doing the Brazilian Portuguese version and target a different audience: Spanish-speaking Latin American evangelicals, English-speaking evangelicals in Nigeria and the Philippines, or Muslim nasheed fitness. Validate first with a web player and a low-priced one-time payment. TikTok is the acquisition channel it hasn't used.

Grade B: a clear playbook, few people know about it, and it can be transplanted to other languages and faiths. But no real sales figures are visible, the moat is only copywriting and ads, free playlists are strong competitors, and the original developer is already rapidly copying it into other languages. Hardly anyone knows about it yet

Data (updated daily) · first launch 2026-09-06 · 11-07 installs 14,330

Android · Total installs worldwide

Data 2026-10-29 → 2026-11-07 (10 days, 10 observations). Google's detail page only refreshes install counts every other day, so a flat day doesn't mean nobody installed.

FIT COM FÉ ("fitness with faith") is an app with only Christian workout music: 150 Psalms rewritten as rap, trap, and drill, sorted into "light, medium, heavy, brutal" playlists. It's really a Brazilian info-product business, and the app is just the delivery shell: payments are collected on Hotmart, and customers come from Instagram and fitness creators. Google Play installs reached 14k in two months, and few people have noticed it yet. What's worth learning is this playbook of "identity audience × one scenario × AI content × payment outside the store"; the most direct way to follow it is to do the same in another language or faith.

### One post, one line: "won't open"

In 2026 May 7, the Instagram account @fitcomfe.oficial posted with the title "CONHEÇA O FIT COM FÉ" (meet FIT COM FÉ):

> No more confusing PDFs. No more scattered links. No more random playlists that don't match your faith.

A comment under the post reads: "Não estou conseguindo acessar." (I can't get in.)

This post reveals two things. First, the product was already selling in May, four whole months before its Sep 6 Google Play launch. Second, it first sold "music packs," a pile of PDFs and download links, and buyers got them and couldn't find or play the songs. The app came later, mainly to fix delivery, and only secondarily to make the product look like a "real app."

On Jul 29, IFBB Pro bodybuilder Larissa Coelho (Instagram 126k followers, bio reads "Corpo, Mente & Fé": body, mind and faith) posted a reel: "🎸 NOVIDADE NO FIT COM FÉ! At your request, the Christian rock playlist is here... LINK NA BIO".

In mid-October, a month-plus after launch, installs started climbing.

### What it is

Open it and it's a music player: home, discover, playlists, now playing, with scrolling lyrics on screen. You can favorite, queue, build your own playlists, and play offline and on the lock screen. Each song maps to a psalm, with titles that read like gym slogans: Psalm 91 is "À Sombra do Altíssimo" (In the Shadow of the Most High), tagged "Pesada" (Heavy); Psalm 29 is "A Voz que Rompe Limites" (The Voice That Breaks Limits), tagged "Brutal." The website says 150 psalms with "new songs every week," and the Instagram bio says 300+ songs.

It's built by ConectaDev.BR in Brazil. Its website describes the company as doing "custom software, infoprodutos (info products) and digital marketing." The same developer account also has an English version, FaithTracks, launched on Google Play on Aug 28 and on iOS on Nov 4. The iOS developer credit is an individual, Anderson Cardoso.

A library this big, updated this fast (the English version went from 600 songs to 1,000+ in two months), is almost certainly AI-generated (inference). Neither the app nor the website mentions AI.

### Where the money comes from: a Hotmart funnel

The last line of the Google Play store description reads "Acesso para compradores e assinantes": for buyers and subscribers. The app isn't the selling point; the pass is.

It runs two landing pages and is testing prices:

| Landing page | Pricing | Payment | Pitch |
|---|---|---|---|
| fitcomfe.online (old) | One-time R$47, struck-through original price R$97 | Hotmart | "App com +200 músicas cristãs para crente maromba" (200 Christian songs for gym-loving believers) |
| fitcomfe.com (new) | R$37.90 / year | Hotmart | "Bate mais que pré-treino" (hits harder than pre-workout) |

Both pages use the standard long-form copy of Brazil's info-product scene: name the pain, list "this isn't for everyone," then a price anchor, a 7-day no-questions refund, and "access instructions emailed right after payment." The new page has a progress bar reading "Founding spots 11.257 / 15.000," implying spots are running out. But the English FaithTracks "Founding members" bar also reads 11,257 / 20,000, with the same numbers: this is hard-coded scarcity, not real sales.

The English version is tested more finely: playfaithtracks.com sells at $23.90 for a year, faithtracks.studio sells $17.90 for six months, $27.90 for a year, and $47.90 lifetime plus family, collected via Stripe.

The money bypasses the store: Hotmart and Stripe take far less than Google Play's 15–30%. The cost is that the Portuguese version's revenue is invisible on Google Play, and it never reached the top grossing charts. The English version is different: it reached #90–#110 on the US Google Play Music top grossing chart, and on November 1 and 2 it also made the tail of the music grossing charts in a dozen-plus countries including the UAE, the Philippines, Nigeria and Saudi Arabia (Google Play charts, 10-29 through 11-06). So at least the English version does collect money inside the store.

How many copies actually sold is not visible from outside.

### Why it can sell

The website puts the pain point in one line:

> Ou a música dá energia… ou combina com sua fé. Quase nunca os dois. (Either the music gives you energy or it fits your faith. Almost never both.)

Gym playlists have energy, but their lyrics feel like they're testing your holiness on the leg press. Worship music fits your faith, but "by the third track you're in rest mode." The old landing page is blunter: "Relying on gym playlists, believers might end up fighting a spiritual battle in the gym."

Brazilian evangelicals make up roughly 30% of the population, and fitness culture is strong. "crente maromba" (a weightlifting believer) is already a meme. The demand has been validated elsewhere too: TikTok videos of "Músicas cristã para treinar na academia"-style playlists have 320k views, and the English "hardest Christian workout song" has 1.9M.

What it really sells is identity, not music. "You don't need to weaken your mind with what you listen to in order to strengthen your body" (the website's own words). Faith plus self-improvement are two of the easiest-selling topics in Brazilian info products, and it stacks them together. Meanwhile, AI makes "being your own record label" nearly free, with no need to fight Spotify over rights.

### How big it has gotten

| Date | Google Play cumulative installs | Source |
|---|---|---|
| 09-06 | Launched | Google Play |
| 10-08 | About 270 | Third-party estimate |
| 10-15 | About 1,400 | Third-party estimate |
| 10-27 | About 8,800 | Third-party estimate; about 1,500 per day around 10-23 |
| 10-31 | 10,958 | Google Play |
| 11-06 | 14,330 | Google Play; past 7 days +5,500 |

It only charted on the Brazil Google Play "Music & Audio" free chart, peaking at #10-31 104 and then sliding to #140–#153. No ratings, no reviews. The English FaithTracks has 14.4k installs, 77 ratings, rated 4.88. Combined, the two versions total about 29k installs.

### Where users come from

**Owned Instagram account.** @fitcomfe.oficial has 31.4k followers and 106 posts, follows only 5 accounts, bio "Sua playlist não combina com sua Fé?" (Your playlist doesn't match your faith?), with the link straight to the landing page. It posted 3 times in one day on Oct 22, and again on Oct 24, right when installs took off from Oct 15 to 27.

**Fitness influencers.** The Larissa Coelho mentioned above posted at least two sales reels. The old landing page has a row of "real reviews" screenshots from Instagram comments, such as willian.amaraloficial writing "Comprei, top mesmo, não vou usar apenas pra treinar, mais no carro também" (Bought it, really great, not just for training, I play it in the car too).

**Meta paid ads (inferred, not directly observed).** The Facebook page "Fit com Fé" has only 1,052 followers but shows 22,438 people talking about it. Few followers with high engagement usually means ads. The landing page links carry Hotmart tracking parameters, and the copy structure is the standard template for this crowd running Meta ads.

**Barely any TikTok.** The brand account has only sporadic videos. The FaithTracks account posted 6 videos with the same copy on Oct 28 and 29, each getting 100 to 500 views. Yet "Christian workout songs" is a topic with hundreds of thousands to millions of views on TikTok. It hasn't tapped into it.

No discussion on X or Reddit, no media coverage, and no one posting their revenue.

### Who it's competing with

- **Free playlists, the biggest competitors.** On Spotify, "Academia Gospel | Gospel pra Malhar" has 69,394 saves, and YouTube has plenty of long "TRAP GOSPEL PARA TREINO" and "Salmos de guerra" channels, many also AI-made. They're free and high-volume, but they're mixed bags. None has the unified packaging of "all psalms, graded by intensity, with lyrics."

- **Treino com Cristo** (treinocomcristo.app): nearly identical positioning, "Fé no fone, força no treino" (faith in your earphones, strength in your training), also 150 psalms, free, funded by Pix donations. No paid funnel.

- **Gospel music packs on Hotmart** : things like "Pacote +5000 Músicas Gospel". Same channel, same audience, but no fitness angle.

- **Faith-fitness apps on iOS** : First Rep, Foundry, TreeFit, Faith & Fit and others. They're training-plan apps that teach you exercises, with no music, and each has 0 to 21 ratings.

- **Big Christian apps like Hallow and Glorify** focus on prayer and meditation and don't touch workout music.

The real moat is thin: the player is ordinary, and anyone can make a song library with AI. What it leads on is positioning, copy and a paid acquisition setup that already works.

### If it were you

**Verdict:** Worth a test, but don't expect to copy the Brazilian version. The opening is in "a different audience," not "yet another FIT COM FÉ": Brazil already has it and Treino com Cristo, and English-market developers are already running it.

**Who it suits:** people who can write conversion-focused landing pages, have run Meta ads, and can find small niche influencers; ideally someone who already speaks the language of a particular faith community.

**Who it doesn't suit:** people who only build apps and hope for organic store traffic. The app part is the least valuable piece here, and store search brings little volume.

**How to do it:**

1. Pick an "identity × scenario" nobody has claimed yet. The closest is Spanish-speaking Latin American evangelicals (a single Spanish "Musica Cristiana para el gym" TikTok already has 650k views); next, English-speaking evangelicals in Nigeria and the Philippines (FaithTracks already shows up at the tail of those countries' grossing charts, proof that people will pay); further out, unaccompanied nasheed for Muslim fitness.

2. Don't build an app first. Use AI to generate 30 to 50 songs, put them in a web player, attach a cheap one-time payment (around $7–10 locally), and see if anyone buys. That's how FIT COM FÉ itself started.

3. Once it sells, wrap an app shell around it as the delivery tool, and keep collecting money outside the store.

**How to get customers:** post short comparison videos, "gym playlist vs worship music," on Instagram Reels and TikTok, recruit a few small faith-and-fitness influencers to promote, and put the best creative behind Meta ads. TikTok is the gap FIT COM FÉ left open, and it's your cheapest breakthrough.

**When to get in:** Q1 of 2027. New-year fitness season (January) is when products like this sell best, and ConectaDev itself is copying language by language, so a Spanish version is likely its next step (inference).

**Signs you've misread it:** you've spent a few hundred dollars on ads and customer acquisition cost exceeds the average order value; or buyers are refunding in bulk, saying "it's free on YouTube"; or within a month or two, several identical AI psalm-workout channels appear in your language.

## FIT COM FÉ (app.fitcomfe) research report

Research date 2026-11-06. Data sources: our googleplay / appstore / metaads databases (agent-im server), plus Jina search and page text, TikHub TikTok search, and x-radar. "AppstoreSpy est." below is history backfilled in the googleplay database's app_day_ext (spread evenly between observations, for trend reading only).

### One line

Brazilian developer ConectaDev.BR (its website describes itself as doing "custom software, **infoprodutos (info products) and digital marketing** ") built a "Christian fitness music" player: 150 psalms rewritten as rap / trap / drill workout songs (clearly batch-generated with AI), sorted into playlists by intensity (leve / moderada / pesada / brutal), with lyrics. **It is essentially a Hotmart info product; only the delivery has changed from a "music pack / PDF link" to an app** : reels and fitness influencers drive traffic on Instagram / Facebook, the landing page takes payment through Hotmart, and buyers then install the app from Play and log in. Play install numbers are a by-product of the paid funnel.

### 1. Who they are and how they sell

- Developer ConectaDev.BR, Play developer id 8572529142717279049, with two apps in the database: FIT COM FÉ (Portuguese, Brazil) and FaithTracks (English, US) [googleplay database app table]. conectadev.online describes itself as "custom software, infoprodutos and digital marketing"; their LinkedIn says the same: "software, infoprodutos, marketing digital". The iOS version of FaithTracks was listed 11-04 ago, with the developer credited to an individual, **ANDERSON CARDOSO** [appstore database, id 6824218056].

- The app itself: on Play, the 1.1.24 version (10-10 updates), 5.2 MB, category "Música e áudio"; the description ends with "Acesso para compradores e assinantes", meaning it is for buyers and subscribers; in-app purchases $3.89-$12.99 [googleplay database app_snap; Play listing page].

- **Two landing pages, testing prices** :
    - fitcomfe.online (older version): "App com +200 músicas cristãs para crente maromba", **one-time payment** , "original price R$97, launch price R$47", 7-day refund, with Hotmart sck tracking parameters. The page also says "no more scattered PDFs or links", suggesting it was first sold as a music pack.
    - fitcomfe.com (newer version): **R$37.90/year** , Hotmart checkout (pay.hotmart.com/D107520842N), a countdown progress bar for "launch spots 11.257 / 15.000"; also hosts a Lovable page like fit-com-fe.lovable.app, with the web player at appfitcomfe.online.
    - The English sister app FaithTracks is testing prices across three domains too: playfaithtracks.com ($23.90/year, one-time payment, no renewal), faithtracks.studio ($17.90/six months, $27.90/year, $47.90 lifetime + family, Stripe checkout), and appfaithtracks.com. **FaithTracks' "Founding members" count is also 11,257 / 20,000** , identical to FIT COM FÉ's numbers. This "spots left" progress is hard-coded scarcity copy, not real sales.

- Catalog: the Portuguese version has 150 psalms + 50 English psalm tracks (IG posts), and the page says 200+ / 300+ tracks; the English version claims 600+ → 1,000+ tracks and "25 new playlists in October". That update pace is only achievable with AI generation (Suno-style tools), though the product never mentions AI.

### 2. Growth data

| Date | FIT COM FÉ cumulative installs | Notes |
|---|---|---|
| 2026-09-06 | – | Listed on Play [googleplay database app.released] |
| 09-24 ~ 10-08 | 169 → 269 | Single-digit installs per day (AppstoreSpy est.) |
| 10-15 | 1,385 | Started ramping up, averaging ~160 per day |
| 10-17 ~ 10-27 | 2,372 → 8,829 | Averaging 300-1,500 per day, peak 10-23 about 1,561/day (AppstoreSpy est.) |
| 10-29 | 8,830 | We began our own collection |
| 10-31 | 10,958 |  |
| 11-03 | 13,347 |  |
| 11-05 / 11-06 | 14,330 | Over the last 7 days +5,500, averaging ~500-800 per day |

- Charts: only ever charted in Brazil's Play "Music & Audio" free category chart, best rank #10-31 104, later slipping to #140-#153; **never reached the Top Grossing chart** , and has no rating data (ratings empty, 0 reviews) [googleplay database chart_rank / app_snap, 10-29 ~ 11-06].

- Sister app FaithTracks (English): listed 08-28, 09-15 711 → 11-05 14,372 installs, averaging 250-470 per day, **rating 49 → 77, 4.88 votes** ; in the US Music category it hit **Top Grossing #90-#110** , and 11-01/11-02 also reached #190-#200 on the Music Top Grossing charts in a dozen-odd countries including the UAE, Hong Kong, the Philippines, Nigeria and Saudi Arabia; US, Canada and Australia Music free chart #85-#187 [googleplay database, 10-29 ~ 11-06]. So the English version is the one actually collecting money inside Play; the Portuguese version's money mostly runs through Hotmart, invisible to Play.

- Combined, the two apps have about 28.7k installs (developer table total_installs 28,702).

### 3. Where users came from (growth tactics)

1. **Instagram owned account + reels content** (confirmed): @fitcomfe.oficial, 31.4K followers, 106 posts, following only 5 accounts; bio "Sua playlist não combina com sua Fé? Aqui tem +300 músicas cristãs para treino". The earliest posts trace back to **2026-04-18** (DXR4qoCDbZS, "App com + de 200 músicas cristãs para crente maromba") and 05-07 ("Nada de PDF…"), 4 months before the Play listing: the product was sold on IG first and the app came later. 10-14, 10-22 (3 posts a day) and 10-24 have dense posting, matching the install ramp from 10-15 to 10-27.

2. **Fitness influencer partnership** (confirmed): IFBB Pro bodybuilder Larissa Coelho (@laricoelhopro, 126K followers, bio "Corpo, Mente & Fé") posted two sales reels: "Chegou o Fit com Fé…" and "NOVIDADE NO FIT COM FÉ! Novo playlist de rock cristão… LINK NA BIO". Recall also turned up Christian fitness creators like ctwinoficial, but I could not verify those original posts (unverified). The "real reviews" screenshots on the .online landing page (betao_nicolau, willian.amaraloficial, etc.) are screenshots of IG comment sections.

3. **Meta paid ads** (likely, but I did not directly see the ads): the Facebook page "Fit com Fé" has only 1,052 followers yet shows "22,438 people talking about this", a pattern of few followers and high engagement typical of ad-driven interaction. The landing pages are standard Hotmart info-product long copy (pain points, "this is not for everyone", price anchor R$97→R$47, 7-day guarantee, countdown spots) with utm / sck tracking parameters, the standard Meta-ads playbook in Brazil's infoproduto scene. The Meta Ad Library web page cannot be viewed without logging in, and our metaads database does not track this page (not finding it does not mean it wasn't running ads).

4. **TikTok is weak** : the brand account @fit.com.f3 has only a few sporadic videos; FaithTracks' TikTok account @app.playfaithtracks.com 10-28/29 posted 6 videos in a row with the same caption, each getting 100–500 views [TikHub search 11-06]. But demand for "Christian workout playlists" is big on TikTok: iisabellabennett's "Músicas cristã para treinar na academia" has 320k views, calebgordon's "hardest Christian workout song" has 13 1.9M, and abrahamboca's Spanish "Musica Cristiana para el gym" has 650k. It hasn't captured that market.

5. **X / Reddit / media** : x-radar shows 60 results in the last 0 days for "faithtracks" and "christian workout music"; no media coverage and no founder posting revenue. The YouTube channel @playFaithTracks has 62 subscribers and 46 videos.

### 4. Competitors

- **Free streaming playlists and YouTube channels** (the biggest competition): Spotify's "Academia Gospel | Gospel pra Malhar" (an editorial playlist by RESOUND Play, 69,394 saves), Apple Music's "Música cristã para treinar", Rapzilla's "Christian Rap Workout Songs"; on YouTube, a flood of long videos and channels like "TRAP GOSPEL PARA TREINO" and "Salmos de guerra" (Louvor e Força, Treino Cristão com Propósito, etc., many of them also AI-generated). Free and high-volume, but those playlists are mixed bags with no unified packaging of "all psalms + graded by intensity + lyrics".

- **Treino com Cristo** (treinocomcristo.app, website): nearly the same positioning: "Fé no fone, força no treino", "150 psalms sung out loud", "Cardio com FÉ", "Treino de Guerra" playlists, free, funded by Pix donations. Launch date unverified; it looks like a copycat.

- **FaithTracks** (same developer, English, Android 08-28 / iOS 11-04): 14.4k installs, #90 on the US Music Top Grossing chart, a replica of this playbook in the US market.

- **Faith + fitness apps on iOS** : First Rep (2026-07,17 rating), Foundry: Christian Workouts (2026-10), TreeFit (21 rating), Faith & Fit (9 rating), Christian Workout for Women (19 rating), and others [appstore library 11-06]. All of them are workout plans that tell you which exercises to do. None are music, and all of them are tiny.

- **Gospel music packs on Hotmart** : "Pacote +5000 Músicas Gospel", "Pack Músicas Gospel Vol.1", "Aplicativo de música gospel". Same payment channel, same audience, but none of them lead with fitness.

- **Big platforms** : Hallow and Glorify, the Christian apps, do prayer and meditation, not workout music. Spotify and YouTube Music's recommendation algorithms will serve you gospel workout playlists, but they don't build for it specifically.

### 5. Why it can break out

- **It hits a real but overlooked tension** : about 30% of Brazilians are evangelical, and gym culture is huge there. "Crente maromba" (a churchgoer who lifts) is already a meme. The landing page says it in one line: "Gym playlists hit hard, but the lyrics don't fit your faith. Worship songs fit your faith, but they're too slow to get you through the last set." TikTok videos on "Christian workout playlists" pull hundreds of thousands to millions of views, which shows the demand is there.

- **AI makes supply nearly free** : 150 Psalms × multiple styles. The English version went from 600 songs to 1,000+ songs in two months. The developer is effectively their own record label, with no licensing costs and no need to negotiate with Spotify.

- **It sells a faith identity, not music** : "You don't need to listen to things that weaken your spirit to make your body strong" and "otherwise a believer has to fight a spiritual battle at the gym." Faith plus self-improvement are the two easiest topics to sell in Brazil's infoproduto scene, and this stacks them together.

- **A conversion machine built on paid knowledge** : Instagram reels and fitness influencer promotion → a long landing page (pain points, price anchor, 7-day refund, a fixed spots-left progress bar) → payment via Hotmart → an email telling you how to install the app. The low ticket (R$37.90–47, roughly $7–9) lowers the decision barrier. The Play app is just the delivery vehicle, and it makes the product feel like a real app, not a PDF.

- **Validate first, then build the app, then copy it to English** : April was selling on Instagram. September was when it hit Play. At the end of August the English version, FaithTracks, launched and reached #90 on the US Play music top grossing chart, which shows the same assets can be reused across languages.

### 6. Differentiation

Compared with free playlists, it packages "all Psalm lyrics + intensity levels + on-screen lyrics + no need to hunt for songs" into a dedicated app, and it gives a identity-based reason to pay. Compared with faith training apps, it does only music and teaches no exercises. Compared with Hotmart music packs, it's an app, not a folder of files. **Is this differentiation why it took off? Partly.** What actually worked was the positioning, the copy, and the paid knowledge funnel, not the product features. The player is ordinary, and the catalog is AI-generated, which anyone can do. The install curve lines up with Instagram posts and influencer partnerships, not with organic store search.

### 7. How many people have seen it

- Almost nobody knows about it yet: no media coverage, 0 posts about it on X, no one publicly sharing revenue, and nothing recorded on TrustMRR or similar trackers.

- But the idea is already being copied. Treino com Cristo has nearly the same positioning. There are many AI-generated "Psalm trap" channels on YouTube. And developers are copying it themselves (the English FaithTracks version).

### 8. What to borrow

- The combination of "a niche identity group × a specific scenario × AI-generated content" (believers × fitness × Psalm music) can transfer to other identity × scenario pairs: Muslim fitness (nasheed without instruments), Spanish-speaking Latin American evangelicals, the evangelical markets of Nigeria and the Philippines (FaithTracks already reached the tail of those countries' music top grossing charts), or scenarios like studying, running, or driving.

- Collect payment outside the store through Hotmart or Stripe, use the Play app as the delivery shell, and sidestep the platform's 15–30% commission. At the same time, test multiple landing pages and multiple price points (one-time, annual, six-month, lifetime).

- Use Instagram content and influencers to sell the "minimum product" first, and build the app only after validating demand.

### 9. Still unclear

- Real paying customers: "11.257 / 15.000" is hardcoded (the English version shows the same number), so it can't be used as a sales figure. How many sold on Hotmart is not visible.

- There is no direct evidence of Meta ad spend (the ad library can't be viewed without logging in, and the metaads library doesn't track it).

- How many Play installs came from buyers versus people who installed without buying.

- Retention: the Portuguese version has 0 reviews and 0 ratings; the English version has 4.88 stars from 77 ratings. That looks fine, but the sample is small, and the landing page openly says it will showcase screenshots of good reviews, so incentivized reviews can't be ruled out.

- The recall card says "FIT COM FÉ is FaithTracks relaunched under a new name." Checking this, that's wrong: the two are the Portuguese and English versions of the same product, running at the same time, not a relaunch.
