Authentication designed for mobile sessions
Token-based authentication that survives app restarts and works across spotty connectivity — a different pattern than typical web session cookies. See API & Backend Development for the general backend discipline this sits within.
Data sync and offline handling
A mobile app frequently needs to work with intermittent connectivity — deciding what syncs immediately vs. what's queued for the next connection is a real architecture decision, not an afterthought.
Push notification infrastructure
Server-side infrastructure to trigger and target push notifications correctly (per user, per platform) — distinct from the client-side permission handling on the app itself.
API design independent of frontend framework
The same backend/API can serve a native iOS app, a native Android app, a React Native app, or a PWA — designing it well once means the frontend platform choice (see PWA vs Native vs Cross-Platform) doesn't require rebuilding the backend.
Questions
What does a mobile app backend actually need to include?+
Authentication that survives app restarts and spotty connectivity, data sync and offline handling, push notification infrastructure, and an API designed independently of whichever frontend framework the app itself uses.
Does the backend change if we choose React Native vs. native?+
No — a well-designed backend/API serves any frontend framework; the framework choice affects the client, not the backend.
How is mobile authentication different from web?+
Mobile typically uses token-based auth designed to survive app restarts and intermittent connectivity, rather than typical web session cookies.
Can LATYNEX build just the backend for an app being built natively elsewhere?+
Yes — this is a common, standalone engagement, independent of who builds the native frontend.
