Challenges
What we came in to solve
The previous vendor had left Offline Viewing half-built — with documented bugs on Android and virtually nothing done on iOS. Users were already reporting issues.
Inherit significant technical debt on top of a limited budget, requiring a full renegotiation to find a project-based model that worked for both sides.
Solution
How we built it
FlyDevs audited the abandoned Android codebase, resolved all bugs, cleaned the technical debt, and built the iOS implementation from scratch — achieving feature parity on both platforms.
- Android rescue
resolved all existing bugs in the half-built Offline Viewing feature and completed the remaining Android implementation
- iOS from scratch
built full Offline Viewing on iOS with complete feature parity to Android
- Technical debt cleanup
removed deprecated libraries including ButterKnife, updated to current Android APIs, ensured full compilable builds on both platforms
- Zero regressions
delivered both platforms without introducing a single regression in existing features
Result
What we delivered
Offline Viewing shipped on both Android and iOS in 6 weeks — stable, fully functional, and regression-free. A long-awaited feature finally in users' hands.
Android + iOS. 6 weeks. Zero regressions.
