It’s day 2 of building my 12th app In public It blocks your phone until you walk. 1,000 steps = 1 hour of screen time We usually 1 shot our apps but We got rejected by Apple 9 times Most likely because our app uses Apple health + screen api Which Apple is sensitive about But this has given us sometime to improve the product We recently added mascots + a widget to the app using Rork And it was super easy, Rork max generated the character + one shotted the widget. Meanwhile we are warming up some IG accounts to go crazy. Will update you guys once it’s live.









Day 4, 5 building & marketing a new app 💪 - Just shipped a small but exciting update, turned the AI-generated prototype into a real feature inside the app. - User can now create workouts and instantly visualize which muscle groups you're targeting. - Feels good seeing things go from idea → prototype → actual product. - Started warming up + post 2 TikTok accounts luckily neither of them got shadow banned. 🤟 Tech Stack: – No code mobile app builder: Rork AI – Mobile: React Native (Expo) – IDE: Cursor – Frontend: Next.js – Payment: RevenueCat – Backend: NestJS – Database + Auth: Supabase – Infrastructure: Railway – AI API: OpenAI (dropping the tech stack here because someone always asks 😌)


Anime AI chat apps are printing $90K/mo → Create a character from a famous anime → Users post convos on TikTok → Those TikToks get millions of views The growth hack? Users create content FOR you Wrap an API Pick a fandom Ship fast with Anything Let TikTok do the rest

Can you still make $1M/mo with a ChatGPT wrapper? → Point camera at coin → AI identifies it → $40/year → 400K downloads month Hobby niches are goldmines Most ignore them But collectors pay Find the obsession Wrap the API Build it with Anything Scale with ads That's it💸
