summary
A mobile tracking app for a three-day Pyrenees challenge with 180 checkpoints uses React Native Expo and local-first storage; the server-dependent design fails in no‑reception stretches, switching to TinyBase plus YJS sync works reliably on six devices in the field but stress tests at 500–1,000 users are too slow; moving to encrypted collaborative sync with Just Tools cuts monthly costs to about $4 and delivers practical offline-first collaboration.
