Free Mermaid diagrams covering push notifications, mobile auth, offline sync, deep links, real-time messaging and more.
Mobile applications operate under constraints that backend services rarely face: intermittent connectivity, aggressive OS process management, strict battery budgets, and platform-specific permission models. Understanding the underlying mechanics of each system — from token registration to background execution — is essential for building reliable mobile experiences.
This collection walks through the key flows every mobile developer encounters. Push Notification Flow traces the full path from your server to the device screen via APNs and FCM. Mobile App Authentication covers the OAuth2 PKCE pattern purpose-built for native clients. When connectivity drops, Offline Sync Workflow shows how local-first apps queue mutations and reconcile on reconnect.
Platform lifecycle concerns are covered in App Launch Lifecycle and Background Job Execution, while Deep Link Routing maps the decision tree from URI scheme to in-app screen. For networking, Mobile API Sync and Mobile Cache Strategy address latency and data freshness trade-offs. Rounding out the collection, Realtime Messaging App Flow and Mobile Payment Flow cover two of the most complex user-facing features any mobile team ships. Every diagram is free to edit and export in Graphlet.
