$25K+/Month From a Vibe-Coded Prayer App (Built in 3 Days)

  • Mau Baron

  • App Developer (PrayerLock)
  • $25,000+ monthly revenue

Mau Baron built PrayerLock, a Christian prayer app, in just 3 days.

Simple concept: it locks your phone until you complete a prayer session. The tagline – “Do you have 1 minute for God?”

💬 Mau writes on X…

our little mobile app just hit 13,000 reviews with a 4.9 star rating on the app store

i always had delusional belief that i would make it but i’d be lying if i said i expected it to reach this many reviews and scale. prayer lock completely changed my life

Revenue: $25K+/month, bootstrapped, all from subscriptions 🤑

His backstory 👇

last year i was posting daily with zero traction so i stopped for 8 months and just obsessed over building a successful product. by the time i came back i was at $20k/month

Mau’s not a developer either – he describes himself as “a finance bro” who used AI tools to build PrayerLock. He published a complete guide on scaling the app – 1.5 million views, 14,000 bookmarks.

Simple utility apps for passionate communities can do serious numbers. Religious groups, hobbyists, fitness subcultures – pick a devoted audience, solve one small problem, charge a subscription 🤔
