About this gig
Need a mobile app that works even without an internet connection?
I build cross-platform mobile apps for Android and iOS with offline support. Your users can continue using the app when their connection is weak or unavailable. Data is stored locally and synced with the cloud when they reconnect.
What I can build:
- Offline-first mobile apps
- Local data storage using SQLite
- Automatic cloud data synchronization
- User authentication and custom workflows
- In-app subscriptions and purchases using RevenueCat
- Clean, responsive mobile app interfaces
What you can expect:
- Well-structured source code
- A functional mobile app based on your requirements
- Testing and revisions based on the package you choose
My Basic package is ideal for a small MVP with 24 screens. Larger projects and additional features may require a custom offer.
Please contact me before ordering. Share your idea and requirements so we can agree on the scope, price, and delivery time.

FAQ
Do I need a Apple developer account for you to build and submit the iOS version?
Yes, you will need an Apple Developer Account for store publication. I use Expo Application Services (EAS) to compile native production binaries in the cloud and push them straight to your Apple TestFlight dashboard for final testing.
How does the offline synchronization handle data conflicts?
The local SQLite storage system queues client-side modifications with timestamps. When network access returns, it resolves synchronization states via an analytical transactional batch sequence against your Supabase backend to prevent overrides.
Can I test your completed applications before ordering?
Absolutely! Message me and I will provide live Google Play Store links to my production-ready application blueprints. You can test them immediately using the built-in "Explore with Demo Data" toggle.
Will you provide the source code repository?
Complete source code ownership is included entirely in the Premium Tier. For Basic and Standard tiers, you can easily unlock full repository access during checkout via the Source Code Gig Extra.
