A French Christian guy turned Muslim "prayer-time reminders" into a 9.99 EUR-a-month prayer app

Prayz sends a prayer reminder every hour, from 8 a.m. to 10 p.m. It launched in July, and by 11-06 had 1,013 ratings on iOS. On Google Play it has 29k installs and has stayed on the French Lifestyle bestseller chart. There's nothing new about the features; Muslim prayer apps have done this for ages. It took off thanks to a TikTok brand account: 6 weeks after opening, it had posted 171 videos and grown to 200k followers. Whether this playbook can be run again in another language is the question this piece tries to answer.

A video teaching you to open the car door for the Holy Spirit

On 24 Sep 2026, the TikTok account @prayzappli posted a 2-min 17-sec video with a single line of caption: "Jean 14:16 #chretien" (John 14:16).

The video opens with: "How do you talk to the Holy Spirit all day long? Remember three things, and save this video." The second thing is a small trick: when you get in the car, open the passenger door and say, "Holy Spirit, come in, sit beside me"; at night when you're struggling, imagine Him sitting at the foot of your bed listening to you. The third thing lands on "pray without ceasing" from 1 Thessalonians 5:17. The product only comes up in the last ten or so seconds: "If you want someone to remind you to do this throughout the day, you can use Prayz, an app that reminds you to pray anytime."

As of 11-06, the video has 2.14M views, 370k likes, and 4,635 comments. The most-liked comment is a joke: "I opened the car door... do I have a car?? Then I'll walk, Holy Spirit." The second most popular is "Lord forgive me, I keep committing the same sin 😭," with 5,987 likes.

The day before, the "Matthieu 6:6" video had 740k views. After these two, the brand account posted roughly 3–5 videos a day, all using the format "scripture reference + #Chretien."

What it is

A French-speaking Christian prayer habit app, available on iOS and Android, with an English and French interface.

The core feature is an hourly push notification. You can set a simple reminder, or pick a theme so the notification becomes a guided prayer. There are a few other features: prayer courses such as "14 days to learn to pray" and "21 days to break an addiction"; a "My Prayers" list where you write down people and things on your heart, and the app keeps reminding you to pray for them; a journal for recording prayers that have been "answered"; and prayer groups and streak tracking.

It costs 9.99 EUR/month or 89.99 EUR/year, shown on the web as "EUR1.73/week," with a 7-day trial. Starting in August, it changed to show the trial prompt as soon as you open the app. A one-star review from 8-30 says: "You have to start the premium trial before you can get into the app, this is forcing people... kind of a subscription trap." A four-star review from 8-02 says: "Now even prayer reminders cost money, sorry, I uninstalled." The paywall sits up front, yet the rating is still 4.66 (888 ratings in the French store, App Store, 11-06).

The developer, Kenny Ahmad, is a French sole trader who goes by Kenny Deen on TikTok, and this is his only app.

How big it actually got

Almost all rating countries are French-speaking: France, Senegal (81), Switzerland, Mauritius, and Madagascar. The Android rating count is more than four times the iOS count, so French-speaking African users are most likely concentrated on that side (inference).

Revenue is not public. A ranking of 60–80 on the French Lifestyle bestseller chart roughly corresponds to a few tens to a couple hundred euros a day in revenue, or several thousand euros a month (estimate; Apple doesn't publish revenue). For an app run by one person, that's enough to live on. The founder also posts videos on TikTok about "how to live off your app."

Where users come from

Step one: the founder spent half a year building a persona. Starting in April 2026, Kenny began posting "Christian + entrepreneurship" content on his personal account @kennydeenspam, such as "Lance toi" (just go for it) and "C'est pas ton voisin qui va payer tes factures" (Your neighbor isn't going to pay your bills). Early videos got only a few hundred views. By 11-06, the account had 107k followers, 3.18M likes, and 846 videos, with a bio reading "I help you put God back at the center of your life," and his wife appears on camera too.

Step two: push people to the web version before the store listing was live. 6-05 He posted "I built a free app to help you pray: Prayz.net" and got 114k views. 6-21 The one after was more direct: "Go to the Prayz.net website to download it, not Google's store or the App Store," with 308k views. At the time Prayz was only a web version, which you could add to your home screen to get reminders. The iOS version launched in 7-15, and Android in 8-03. In other words, he validated demand with the web version first and only then built the store versions.

Step three: open a brand account and produce content in volume. 9-04 He publicly recruited creators on his personal account: "I'm looking for creators to talk about my app; it doesn't matter if you're famous." 9-22 The brand account @prayzappli posted the earliest video visible today, and in 6 weeks posted 171 videos, reaching 202k followers and 1.86M likes. Total views during that period exceeded 10M (TikTok, 11-06). Many videos reached hundreds of thousands of views: "Jean 16:13" at 430k, "Nombres 23:19" at 430k, and "Éphésiens 4:30" at 360k.

The videos fall roughly into two types. One is the teaching format from the opening example: "scripture + three points + a mention of the app at the end." The other is narrative: 10-29's "Et si tu pouvais entendre Dieu directement ?" (What if you could hear God speak directly?) tells of a person who could hear the Holy Spirit, who at a wedding didn't marry a fraudulent bride, who found a lost child on the third level of a parking garage, and who finally went out every night to pray in the streets and stopped a street violence incident. The same caption was posted three times on 10-29, 11-01, and 11-04, with 510k, 300k, and 170k views. They were repeatedly testing the same hook.

Other channels: The founder reposted the same videos to Facebook and Instagram. Inside the app, inviting 1 friends gives them 2 month of membership, and inviting 6 friends gives a year.

Not found: no paid ads or boosted hit products turned up. Judging by organic play volume, the current growth can be explained without paid acquisition.

Why users pay

The word that keeps coming up in reviews is "busy": "If you're busy at work and have no time to pray all day, it lets you pray once an hour" (7-16); "Even with coworkers around and no way to pray every time, the reminder gets me praying in my head and turning back to Jesus" (7-22).

It's the same feeling as the video comments: you want to talk to God more, can't manage it, and feel guilty. The first line of the store description is "without guilt and without forgetting." Inside the app, the hourly push is itself a prayer, and you don't have to open the app. The value is delivered by the push, not by the user opening it.

Who it's competing with

Two things stand out. First, French-language Christian apps have been hot for 2026 years, with several indie developers alone, but most do Bible reading and daily verses. Only Prayz offers "hourly prayer reminders," and I haven't seen anyone copy it yet. Second, Dove and Prayminder show the concept itself has no barrier. Building it doesn't mean it sells. What decides the outcome is the content channel.

If it were you

Verdict: This is an app where "anyone can build the concept, anyone can learn the channel." Its moat is a TikTok brand account that makes faith content, and a brand account can reach 6k followers in 200 weeks. Following its method in another language can be done again.

Who it's for: People who are inside a Christian community themselves, or who have a partner like that, and who can post faith short videos daily in that language. The most promising are Brazilian Portuguese and Latin American Spanish evangelicals: the audience is much larger than the French market, with more Android users and lower spending power, but volume makes up for it. The English market has more competitors and more content accounts, but no one has yet done the combination of "hourly reminders + content account" well.

Who it's not for: People who don't feel anything about faith and just want to copy a template. Comments and video scripts depend on very specific faith language (the Holy Spirit, sin, fulfillment, ceaseless prayer). One wrong sentence and viewers will notice right away. Also skip it if you only build products and won't post videos every day. Dove ended up that way.

How to build it: Copy Prayz's product. It can ship in two weeks: hourly pushes (each push includes a line guiding a prayer), a prayer list, a fulfillment log, check-ins, and groups. Price at 9.99 per month or 89.99 per year (local currency), with a 7-day trial. A paywall up front will draw some bad reviews, but given Prayz's ratings the cost is small. Start with a PWA or Android, don't wait for iOS.

How to get users: Use two accounts. Start with a personal account saying "I'm a Christian, I'm building something to help people pray" to gather an audience. Then open a brand account posting 3–5 times a day, using two formats: tutorial videos ("verse number + three points + a mention of the app at the end") and story videos ("What if you could hear God?"). Repost hooks that went viral every two or three days. Invite 6 people for a free year. This referral loop can be copied directly.

When to get in: The French market already has similar competitors like Loucio. Whether there are equivalents in the Portuguese and Spanish markets was not specifically checked (unverified), so search the local stores and TikTok before starting. Around Christmas and New Year, believers make "pray better this year" resolutions, so the best plan is to get the content account going before mid-December and launch paid in January.

What would show you're wrong: ① If Prayz's brand account stops posting for a month and its French Top Grossing rank still holds in the top 120, the product itself keeps people, the content account is just an entry point, and the barrier to following is lower than you think. ② The reverse: if the brand account's views drop and the app falls off the charts with it, this is a "content business" where the app is just the cash register, and anyone following needs to be sure they can post daily for the long run. ③ If within six months Hallow or YouVersion adds "hourly reminders" and pushes into Portuguese and Spanish markets, the gap gets taken by a big company.
