Challenge
Separate native apps had drifted — feature parity, QA cost, and release cadence were unsustainable for a multi-region fleet product.

Atlas Fleet replaced drifting native apps with one Flutter codebase for drivers and dispatchers. We introduced clean architecture, feature modules, Figma-synced design tokens, offline queues for low-connectivity routes, and role-based experiences so managers and drivers never share the wrong surface. Weekly releases replaced painful dual-platform trains.
A Flutter app for Android and iOS that gives dispatchers and drivers real-time routing, compliance, and vehicle health.
Narrative
How the engagement moved from constraints to a shippable system.
Approach
We rebuilt on Flutter with a clean architecture, feature modules, and shared design tokens synced from Figma.
Solution
Atlas Fleet ships weekly from one codebase with native maps, offline queues, and role-based experiences for drivers and managers.
Scope
What we delivered
Flutter apps for Android and iOS with shared modules
Driver and dispatcher role experiences
Offline-first sync and conflict resolution
Maps integration and vehicle-health views
CI pipelines with golden-path UI tests
Design token pipeline synced from Figma
Highlights
What stood out
70% reduction in release overhead vs dual native apps
Feature parity enforced by a single codebase
Offline queues that survive dead zones on rural routes
Weekly release cadence adopted by product ops
Engagement flow
A repeatable rhythm from discovery through hardening — tuned to this product’s constraints.
01
Parity audit
Catalogued Android/iOS drift, painful flows, and connectivity failure modes across regions.
02
Architecture & tokens
Stood up Flutter clean architecture, module boundaries, and Figma token sync.
03
Feature migration
Ported routing, compliance, and health features with offline-first data layers.
04
Cutover
Staged regional rollouts with dual-write monitoring until native apps were retired.
