Drift Atlas
Our offerings
From initial concept to a maintained release on Google Play.
Native Android apps
Kotlin from day one. Apps that feel at home on Android and run on modest hardware.
Compose interfaces
Declarative UI with Material 3, adaptive layouts and smooth motion.
Offline data handling
Room and DataStore store everything locally, keeping the app alive in a tunnel or on a plane.
Battery & performance
We profile start‑up, jank and background work, then monitor Android Vitals after each release.
Accessibility first
TalkBack labels, strong contrast and large‑text support are built in, not added later.
Long‑term care
Signed builds, staged rollouts on Google Play, and ongoing updates as Android evolves.

Our workflow
A clear, predictable path from idea to released app.
Discovery
We define the problem, target users, and the boundaries of the app.
Architecture
We map screens, data flow and permissions before writing production code.
Build
Kotlin, Compose and tests delivered in small builds you can install and try.
Release & care
Staged rollout on Google Play, then monitoring, fixes and updates for new Android versions.
One-way data flow: the interface observes state, and the repository owns the data.
