Offline-First Mobile Architecture — Sync That Survives Bharat Networks
Offline is the default state
Field apps in Bharat face 2G fallbacks, tunnel dead zones, and shared-device usage. Design for offline-first: local SQLite/WatermelonDB as source of truth, UI reads locally always, sync runs opportunistically in background.
Sync and conflicts
Last-write-wins suffices for single-user data; multi-user edits need field-level merging or operational transforms. Queue mutations with retry budgets and user-visible sync states (pending/synced/failed) — silent queues breed distrust and duplicate submissions.
Media on bad networks
Compress before upload, chunk large files with resume, and sync media only on WiFi by default with user override. Field-team adoption lives or dies on whether the app works in a basement parking lot.
