Vibe coding is fun… but it’s also like playing a slot machine. You spin prompts, burn credits, and hope the app isn’t packed with bugs. In this video, I test Rocket.new’s new Precision Mode, which is basically “vibe coding without gambling.” Instead of endless retries and prompt gymnastics, I use simple English to generate a real, production-style mobile app—then I control what gets generated page-by-page so I’m not wasting time or tokens. I build a full Android GIF-only chat app from scratch: registration + login, user search, friend requests, and a WhatsApp-style UI—while disabling plain text messages completely. Then I swap the mock auth system for a real Supabase backend, push seed data so the app is instantly testable, and confirm the friend system actually works end-to-end. After that, I use Rocket.new’s slash commands to update branding fast (theme hex colors, logo, and specific screen content) without breaking the whole project or losing context. The big takeaway: Rocket.new feels like it’s engineered for shipping, not just demos. You can sync to GitHub, download the project, build an APK, and install it on your phone—meaning you’re genuinely close to publishing to the Play Store if you want to take it further.
