Bappfy turns a description of your app into a real one. It plans the screens with you, then writes production-ready Expo / React Native code, screen by screen. The same project ships as an iOS app, an Android app and a live website. Edit by chat, switch between five themes, connect a database and sign-in, earn with AdMob, and download the full source code or push it to GitHub. No code, no templates. From $19/month.
