I spent way too much time building mobile apps from scratch, so I made LaunchToday (Expo boilerplate) to fix that. It’s a production-ready starter kit that includes:

- Authentication (Magic links, OAuth, etc.) - Backend integration (Works with Firebase, Supabase, or your own API) - Payments (Stripe & IAP) - Localization, monitoring, dark mode, and more

Since launching, startups have used it to cut weeks off development time. If you're a YC company building a mobile app, don’t start from scratch—focus on your product instead.

Would love to hear your thoughts! What’s been your biggest pain point in mobile development?
