Sink or swim:proving ideas in production, fast
summary
Built two Android apps: a Midjourney-generated wallpapers app and a kids bedtime-stories generator using chat AI, both shipped on the Play Store and responsive to large screens. Rapid Google Ads tests deliver surprising scale—1,500 installs from €100 campaign—but crashes on obscure Xiaomi models and burst spending burn budget in 30 hours. Prototype stack uses GitHub templates, AdMob (banner/native/interstitial), GDPR consent and Firebase functions for notifications. Economics flop: €8 revenue from wallpaper app and €5 from stories.
