A fitness app's description names another app: the third copy from a Vietnamese-linked app factory
What it is A free, ad-supported 7-minute lazy home workout app, the third version cloned out of an app factory.
Why it took off The factory re-listed Yolo Fitness, which already had 670k installs, under a new account and name, bought paid installs to push into low-barrier countries like South Africa and Nigeria's category charts, and got five-star ratings across the board in its first few weeks.
CHow you could follow Not worth copying as-is. If you do it, learn the multi-account matrix tactics, build the flagship's most-wanted feature ("ads don't interrupt training"), and localize into markets outside Portuguese that are underserved.

On Nov 6, open "Home Workout: Lazy Fitness" on Google Play. The second line of the description reads "Yolo Fitness turns 'I'll start tomorrow' into 'done in 7 minutes.'" Yolo Fitness is an app under another account from the same company. This lazy home workout app, listed Oct 10, got over 30k installs in a week. The product has nothing new; the growth came from an app factory: when one category works, swap the account and name and launch again. Below is how it was done and whether you should follow it.
A line of copy nobody updated
On the store page, the developer is "OMG! Bros" and the app is "Home Workout: Lazy Fitness." But the body text mentions "Yolo Fitness" twice: "Yolo Fitness turns 'do it tomorrow' into 'done in 7 minutes'" and "Carry Yolo Fitness as your pocket coach" (Google Play store page, 11-06). Its privacy policy page, meanwhile, names a third app, "CollageLab."
Tracing back from the developer site growly.life, you can find three developer accounts: Growly, STARVIA COMPANY LIMITED, and OMG! Bros. They share one website and one contact email, with 23 apps total and roughly 25M installs (Google Play, 11-06). The official company name on the site is Growly Limited, self-described as "AI-powered apps… Powering millions of devices." The contact email's name is Vietnamese, so the factory is likely in Vietnam (inferred).
What it is
A bodyweight home training app for people who don't like exercise: starts at 7 minutes, no equipment, plans by goal such as fat loss or muscle gain, each move has video and animated demos, plus daily reminders. Fully free, ad-supported, no in-app purchases (Google Play, 10-29 to 11-06). Android only.
The numbers: ~30k a week, on low-barrier countries' category charts
| Launched | 2026-10-10 |
| Total installs | 10-29 5,801 → 11-03 29,244 → 11-06 37,366(Google Play) |
| New in the last 7 days | +31,565 |
| Rating | 11-06 store page shows 4.7 stars, about 300 reviews |
| Best rank | #11 on South Africa's Health & Fitness free chart (10-30), #32 in Nigeria, #39 in Canada, #49 in the Philippines, #52 in Argentina; best in the US: #174 |
It has only charted in category rankings, never the overall chart, let alone Top Grossing. And its rank is falling: in 11-06 South Africa dropped to #49, Canada to #86, Mexico to #97, while still on category charts in 11 countries.
Inside this factory it's a small number. Its flagship Yolo Fitness (listed Aug 27) already has 670k installs and grew another 7k in the last 89 days. Earlier, "Workout at Home App: Fitness" (listed July) reached 2.22M (Google Play, 11-06).
The same app, listed five times
Looking only at the home fitness category, this factory has shipped at least five versions in four months:
| Launched | App | Account | Installs (11-06) |
|---|---|---|---|
| 07-19 | Workout at Home App: Fitness | Growly | 2.22M, with IAP $9.99–29.99 |
| 08-27 | Yolo Fitness: Lazy Workout | STARVIA | 670k |
| 10-10 | Home Workout: Lazy Fitness (this app) | OMG! Bros | 37k |
| 10-20 | 28 Days Workout Challenge | Growly | 129 |
| 10-29 | Home Workout: Fitness App | STARVIA | 368 |
AI language practice, AI photo editing, and battery-emoji apps have each been copied more than once too. The OMG! Bros battery-emoji app is another duplicate of STARVIA's.
Why publish repeatedly? One version spreads across country groups and keywords, multiple accounts spread the risk of bans and downranking, and whichever one takes off gets more budget (inferred). The first version used IAP subscriptions; later ones switched to free with ads, so it's clearly testing both monetization models within one category.
Where users come from
Paid acquisition is confirmed at the factory level. In the Meta Ad Library, the Growly family has 7 Facebook pages running ads; LunaSpeak's two pages have historically run over 8,500 ads combined; Genify 4,711. One page was originally named "Yolo Fitness - Your AI Trainer," started running ads in 10-15, has 991 historical ads, and later switched to promoting another app, Zenda. Pages get reused across products too. One Brazilian review of Yolo Fitness reads: "vim atrás de um anúncio do Instagram" (I came from an Instagram ad, 10-30). This app's own ads weren't found, but not finding them doesn't mean they weren't run.
Targeting low-barrier countries for category charts. South Africa, Nigeria, the Philippines and Argentina's Health & Fitness charts let a few thousand daily installs reach the top 50, after which organic and search traffic adds a little more. In the US it only reached #170 or below.
Five stars for the first few weeks. 11-04 The first time I saw its rating distribution, 240 ratings were all 5 stars, not a single bad review; 11-06 still all five stars. The reviews visible on the store page look like this: 11-03, "Dance boy" writes "not bad 😁", "Meso tshipa" writes "cool" — one or two words, from users with names that look South African and Nigerian. This kind of distribution usually comes from in-app prompts asking for good reviews, and could also be fake; I can't tell which (unverified).
The name is the search term. The title stuffs in "Home Workout" and "Lazy Fitness," both big keywords; the one-line summary is "Quick 7-min home workouts for lazy days. No equipment."
"lazy workout" and "lazy girl workout" are big topics on TikTok, with single videos getting hundreds of thousands to millions of views, so the demand is already there. But no videos mention this app or Yolo Fitness. On X, zero mentions in the last 30 days.
Where the money comes from, and what users say
Only ads. There aren't many reviews for this one yet. Look at its original, Yolo Fitness, and you'll see that the Brazilian users' bad reviews are almost all about one thing:
"I've never seen an app with this many ads. I can't even get into the settings page. I understand ads are necessary, but this wastes too much time. Uninstalled." (10-04,1 stars)
"Too many ads, you can't keep up with the workout. Fix it: put the ads between sets." (10-16,1 stars)
"I just don't like ads interrupting my workout." (10-18,4 stars)
But the most-liked positive review: "Perfect! Free, with a timer and music, and voice prompts for when to rest and when to start." (10-13,20 likes) What users want is simple: free, someone guiding the workout, and no ads interrupting it.
The math is probably this: buy installs in countries where CPI is cheap, then earn back the cost with interstitial ads (inferred). Revenue and ROI are not visible from the outside.
Who it's competing with
"Lazy fitness" is not a new term. This niche is already crowded:
| Product | Scale (Google Play installs) | How it charges |
|---|---|---|
| Home Workout - No Equipment(Leap Fitness,2017) | 304M | Ads + subscription, the category prototype |
| Fitify(2018) | 32.3M | Subscription |
| JustFit - Lazy Workout(2022) | 12.5M, #55 on the US Health & Fitness Top Grossing chart | Subscription; the "lazy fitness" positioning was theirs first |
| LazyFit: Chair Yoga & Pilates(2022) | 7.88M | Subscription |
| Home Workout for Women(PT POLEWALI DIGITAL,2026-08) | 970k, 7 days +220k, #1 on the Brazil category chart | A new package from the same period, also targeting emerging markets, and it took off much faster |
| Lazy Workouts for Women(SWIFTFLYERS,2026-08) | 340k | Almost the same positioning |
Home-workout or lazy fitness apps with those words in their titles number 30+ on the charts, and quite a few new ones launched in 2026.
How many people know about it
This app itself is unknown: no public revenue, never on the Top Grossing charts, and nobody mentions it in media or social platforms. But everyone in the niche knows the playbook. The factory has already copied it five times, and several other outfits are doing the same thing in the same period.
If it were you
Verdict: There's something to learn here, but not worth following. The product itself has no barrier to entry, and the category is already filled by established big players, subscription operators, and a batch of factories that also buy paid acquisition. This one is even only third-ranked among its own factory's versions, and its rank is sliding.
Who it's for: Small teams already running "paid acquisition + ad monetization" utility apps who want to learn a matrix playbook: same codebase, swap accounts, package names, and titles, and spread across countries and keywords.
Who it's not for: Indie developers hoping to grow through the product and organic traffic (no user here was attracted by the product); people without a paid acquisition budget or ad-aggregation experience; people who want to build a subscription (JustFit and LazyFit have been spending on it for years).
How to approach it: If you must touch this space, don't copy this app. Do the one thing they all got wrong: ads only between sets, and never interrupt the workout. That was the complaint named most often in the original's reviews. On language, the Portuguese market is already contested by Yolo Fitness and PT POLEWALI, so the remaining room is more likely in under-localized markets like Indonesian, Vietnamese, and Turkish (inferred, not verified).
How to get users: In low-CPI countries, buy installs through Meta or an ad network, first push to the top 50 of the local Health & Fitness chart, and use titles with precise local-language search terms. Test with a small budget whether 7-day ad revenue can cover the install cost.
When to start: January is New Year weight-loss season, and fitness paid acquisition and search both rise, so if you're testing, launch before December (inferred).
What would mean you read it wrong:
- This product's December rebound, back to the top 20 in South Africa and Nigeria, shows the factory is adding budget, so the ad-monetization math works and is worth studying closely.
- If the factory stops copying new fitness versions, or pulls Yolo Fitness down: this category doesn't make money.
- If your small-budget test shows 7-day ad revenue below 30% of install cost: don't add money.

Bottom line
It's not an independently successful product. It's a clone copied by the Vietnamese app factory Growly Limited (contact [email protected]) under its third developer account, "OMG! Bros": the body text still carries the sister app "Yolo Fitness"'s name. It reuses the already-proven "lazy 7-minute home workout" template and launch playbook: buy paid acquisition (Meta / Instagram ads), first chase the category charts in low-barrier countries (South Africa, Nigeria, Philippines, Argentina), monetize through ads, and in the first few weeks after launch run a wave of all-five-star ratings. Installs went from 10-29 5,801 to 11-06 37,366, which is a small figure within the factory as a whole.
1. What it is
- Listed on Google Play, 2026-10-10 (data card); developer "OMG! Bros", developer website growly.life, email [email protected] (googleplay.app table).
- Bodyweight home training, marketed as "built for people who don't like exercise": starts at 7 minutes, no equipment, plans by goal, with video and animated demos of moves. Free, includes ads (ad_supported = True), no in-app purchases (offers_iap = False, app_snap 10-29~11-06).
- The store description reads "Yolo Fitness turns "I'll start tomorrow" into "done in 7 minutes"" and "Think of Yolo Fitness as a personal trainer in your pocket" (Play store page, 2026-11-06 read via r.jina.ai). Clearly the copy was lifted directly from the same factory's "Yolo Fitness: Lazy Workout" (ai.starvia.lazyworkout).
- The privacy policy is hosted at zenolab.app/omgbros/privacy-policy/, but the page describes a different app from the same developer, "CollageLab": the template was copied wholesale.

(googleplay.app_day; Google updates install counts only every few days, so single-day increments are totals over several days)
- 7 days of new installs 31,565 (app_profile.installs_gain_7d).
- Charts: it has only ever appeared on the HEALTH_AND_FITNESS free category chart, never on the overall or Top Grossing charts. Its best rank was #11 in South Africa (10-30), followed by #32 in Nigeria, #39 in Canada, #49 in the Philippines, and #52 in Argentina; in the US it reached #174 at best. Its rank is sliding: South Africa 12→49, Canada 43→86; meanwhile the number of countries where it charts went from 11 to 11, but the set was replaced, with Mexico, Spain, and the Netherlands newly appearing (chart_rank 10-29~11-06).
- Ratings: when 11-04 was first captured, 240 reviews were all 5 stars (histogram [0,0,0,0,240]); 11-05 became 259 reviews, and 11-06 became 283 reviews, still all 5 stars. The 11-06 store page shows 4.7 stars from 298 ratings, so negative reviews have only just started coming in. The reviews visible on the store page are one- or two-word comments like "not bad 😁" and "cool", and the reviewers' names appear to be from South Africa and Nigeria.
3. The factory behind it: Growly / STARVIA / OMG! Bros
Reverse-looking up the developer websites growly.life / starvia.ai in the googleplay database turns up 3 developer accounts and 23 apps, about 25.2M installs in total (app_profile, 2026-11-06):
- Growly: LunaSpeak (6.65M), Artify (3.85M), Genify (3.35M, listed 11-03), Beautix (2.53M), Workout at Home App: Fitness (life.growly.herfit, 2.22M, with in-app purchases $9.99–29.99), SpeakUp AI (1.43M), Daily Bible (740k), 28 Days Workout Challenge (listed 10-20), and more
- STARVIA COMPANY LIMITED: Amora (830k), Battery Emoji Buddies (780k), Yolo Fitness: Lazy Workout (670k, listed 8-27, #13 on Brazil's free Health & Fitness chart), Zenda, PixGen, Sleepzy, Home Workout: Fitness App (listed 10-29), and more
- OMG! Bros: DailySpeak (1.15M), RoomAI (610k), Home Workout: Lazy Fitness (this app), Battery Emoji Buddies & Themes (listed 10-29; a copy of STARVIA's version)
This factory's playbook is clear: once a category works, swap the account, package name, and title, and go again. The home-fitness category alone has at least 5 versions: herfit (July) → Yolo Fitness (August) → this app (10-10) → 28 Days (10-20) → Starvia Home Workout (10-29). The battery-emoji, AI speaking, and AI photo-editing categories have each been copied more than once too. The company name on the growly.life website is "Growly Limited," and its public pitch is "AI-powered apps… Powering millions of devices."
4. Where users came from (growth tactics)
- Paid acquisition (Meta / Instagram): confirmed at the factory level; this app's own ads were not captured. In the metaads database, Growly-linked Facebook Pages running ads number 7: the two LunaSpeak Pages have over 8,500 ads in their combined history, and Genify has 4,711. Notably, one Page was originally called Yolo Fitness - Your AI Trainer (page_id 1354177281110169, first ad 10-15, 991 ads in history, 367 currently running) and later switched to promoting Zenda. This shows the fitness line did use Meta ads, and Pages get shuffled between products. A Yolo Fitness Brazilian reviewer wrote "vim atrás de um anúncio do Instagram" (I came because of an Instagram ad, googleplay.review 10-30). This app's own package name shows no landing ads in the metaads, googleads, or tiktokads databases. But these databases only track a fixed list of products, so that doesn't mean it never ran ads.
- Start with the category charts in low-bar countries. The best ranks are in South Africa, Nigeria, the Philippines and Argentina, where the Health & Fitness category is easy to crack. The US only ranks #170 and below. A few thousand to ten-odd thousand daily installs is enough to get into the top 50 there. Once you chart, you pick up some organic traffic and store search traffic on top.
- Review farming / prompted five-star ratings. Less than a month after launch it had 240 reviews, all 5 stars with zero negatives, and nearly all one- or two-word comments, the classic pattern of an in-app rating prompt, and possibly fake reviews (unverified). Among its sister app Yolo Fitness's 6,000 ratings, most are short Brazilian comments like "muito bom" and "amei."
- Store search (ASO). The title packs in two high-volume keywords, "Home Workout" and "Lazy Fitness". The description reads "Quick 7-min home workouts for lazy days. No equipment".
- Content and creators: none found. "Lazy workout / lazy girl workout" is already a big TikTok topic, with single videos getting hundreds of thousands to millions of views (TikHub search), so the demand is there. But no videos mentioning this app or Yolo Fitness turned up. On X (x-radar, last 30 days), zero mentions.
Where the money comes from: the app has no in-app purchases and runs entirely on ads. Reviews complain a lot about this ("muita propaganda", "deveria ter menos anúncios"), though those complaints are about Yolo Fitness. Paid acquisition is most likely aimed at countries with very low CPI, with ad revenue covering the cost (inferred). Sibling app herfit uses in-app subscriptions, so the factory is testing both monetization models within the same category.
5. Competitors
| Competitors | Platform | Launched | Scale (Google Play cumulative installs) | How it differs |
|---|---|---|---|---|
| Home Workout - No Equipment(Leap Fitness) | Android | 2017 | 304M | The category leader and the template's prototype. This app just repackages it as "lazy" and adds paid acquisition. |
| JustFit - Lazy Workout(ENERJOY) | Android/iOS | 2022 | 12.5M, Top Grossing in the US, #55 | The "lazy fitness" positioning was pioneered here, earning through subscriptions. This app is free and ad-funded. |
| LazyFit: Chair Yoga & Pilates(Next Vision) | Android/iOS | 2022 | 7.88M, Top Grossing in Germany, #19 | Focused on chair yoga and Pilates, paid subscription |
| Fitify | Android/iOS | 2018 | 32.3M | Equipment plus personalized plans, subscription-based, premium-leaning |
| Home Workout for Women(PT POLEWALI DIGITAL) | Android | 2026-08 | 970k, 7-day +220k, Top Grossing in Brazil #1 | Launched a new-market pack around the same time, and it took off much faster than this app. |
| Lazy Workouts for Women(SWIFTFLYERS) | Android | 2026-08 | 340k | Nearly identical "lazy" positioning, a copycat in the same period |
| Yolo Fitness: Lazy Workout (STARVIA, same factory) | Android | 2026-08-27 | 670k | This app's original version, with near-identical copy |
| Workout at Home App: Fitness (Growly, same factory) | Android | 2026-07-19 | 2.22M | Same factory, uses in-app purchases |
| Apple Fitness+, Google Fit / Fitbit built-in workouts | Big-company features | – | – | Requires a subscription or hardware, and doesn't target budget Android users |
The category is badly saturated. In the Google Play library alone, more than 30 fitness apps with "home workout" or "lazy" in the title are charting, and plenty launched within the last 2026 year (EZ Health, LOWBYTE, TOMODEV, Origin Pix, etc.).
6. Differentiation
There's essentially no product differentiation. The features, copy and structure match sister apps and older products like Leap Fitness. The only positioning is "lazy / 7 minutes", and JustFit and LazyFit have been using that wording for 2022 years. It made it through because of factory-level capability: once a category works, clone it across accounts, add paid acquisition, choose countries, and run the old review-farming playbook. So differentiation isn't why it worked. The distribution playbook is.
7. How many people have seen it
- Revenue isn't public, and it hasn't charted on any top-grossing list. No media, X or TikTok coverage of the app.
- The factory keeps a low profile, but STARVIA has listings on AppBrain, Apptopia and AppGazers, and its Play developer page is public.
- "Lazy fitness" is already crowded. In the second half of 2026 alone, several companies including SWIFTFLYERS and PT POLEWALI were working it. This factory has also already cloned it 5 times.
8. What to borrow
- Once a category works, reuse the same copy and code under new developer accounts and new package names, and spread versions across countries and keywords. That lowers the risk of any single account getting banned or downranked.
- Ad-funded free apps first chart in low-bar category charts like South Africa, Nigeria, the Philippines and Argentina. A small number of daily installs gets them the organic traffic that comes with charting.
- A Facebook Page is reused across products. Yolo Fitness's Page was later used to promote Zenda, which saves the cost of building a new Page.
9. Still unclear
- No direct evidence on whether this app runs ads or which channels it uses (only confirmed that the factory's other apps buy on Meta).
- Whether 240 reviews all at 5 stars are from prompts or fake, there's no way to tell.
- Unknown whether ad revenue covers acquisition costs, or what retention looks like.
- The legal relationship between OMG! Bros and Growly/STARVIA is unverified: the website and email are the same, but the company entities haven't been checked. zenolab.app only hosts the privacy policy, and its relationship to the factory is unclear.
