Fleet ops Flutter app — 12K daily drivers.

Replaced 3 legacy driver apps with a single Flutter app: offline-first, voice-driven, embedded routing. 12K DAU at peak.

Driver apps that assume 5G and high literacy fail on the actual road. We built one that works on entry-level Android, doesn't drop on a 2G handover, and lets the driver speak instead of tap.

⌖ The brief

What they asked for.

Drivers were juggling three separate apps with mismatched workflows. Replace all three with a single, offline-tolerant, voice-driven Flutter app that works on the worst-connected device and the busiest dispatch day.

▣ How we approached it

The approach.

01

Offline-first sync

All driver actions queue locally; conflict-resolved sync when connectivity returns. Drivers don't lose work because they entered a basement.

02

Voice-driven UX

Voice input + TTS for status updates, address confirmation, and exception flagging — for drivers with low literacy and busy hands.

03

Embedded routing

Pragmatic routing tuned for Indian roads — turn restrictions, road conditions, return-leg matching.

04

Built for entry-level Android

Sub-50MB install, tested on Android Go devices, lean memory profile.

◇ What we shipped
