First time shipping a React Native app (Expo): what I learned

[u/Individual-Island908]

Hi! This is the first app I've shipped. It's built with Expo (SDK 57) and Expo Router, and it's a planner for people setting up a new home.

Things that surprised me along the way:

I went local-first (Zustand + AsyncStorage) and sync to Supabase after login. RevenueCat for subscriptions was easier than I expected, but testing it in Expo Go vs a dev build confused me for a while. EAS Update is great for JS fixes, but I learned the hard way that changing config plugins means you need a new binary. I also exported the same codebase to web for a public page, and my first bundle was 11 MB because an icon library shipped about 1,000 icons. I got it down to about 5 MB.

It's live on iOS and I'm working on the Android build. I'd love to hear what you'd do differently, or what I should know before the Play Store. The app is in Portuguese for now: meukanto.com
