Wise Global needed reliable offline access for its discipleship app used by church leaders across 10+ African countries with unstable internet connectivity.

We assembled a team of 6 reliable professionals and, in 2.5 months, built an offline‑first architecture using Flutter for cross‑platform UI and SQLite for local storage, augmented by native Kotlin and Swift modules for efficient background downloads and data sync.

• Local progress tracking schema for prayers, training completions, and sharing activities
• Conflict‑safe batch sync logic to upload offline data upon reconnection
• Intuitive UI indicators for download status, offline availability, and sync progress
