Driver app with offline-first proof of delivery
1,100 drivers across low-connectivity routes needed a delivery app that works when the network doesn't.

The Problem
Paper PODs took 6 days to reach billing. Drivers on rural routes lost signal for hours, and the previous app simply failed.
Before our intervention:
- 6-day POD turnaround
- Paper-based disputes
- App unusable offline
The Outcome
Depot-by-depot rollout with printed quick-start cards in three languages.
After launch:
- Same-day POD sync
- Photo + GPS evidence per stop
- 100% offline capability
How we designed and engineered it
Discovery & Insights
We rode along on 14 routes and logged connectivity. 38% of delivery stops had no usable data connection.
UX & System Design
A three-tap delivery flow with oversized targets, works-in-sunlight contrast, and a sync status that never lies.
Engineering & Quality
Local-first SQLite store, conflict-safe sync queue, compressed photo PODs and signature capture.
