Non‑negotiables
Four rules we never bend.
On‑device first
All data stays on the phone.
Battery discipline
We treat background work as a cost and measure it.
Accessible UI
Screens work with TalkBack, large text and proper contrast.

What we deliver
From sketch to release, we handle every Android detail with care.
Native Android apps
Kotlin from day one. Apps run smoothly on modest hardware.
Compose interfaces
Declarative UI, Material 3, adaptive layouts and fluid motion.
Offline data handling
Room and DataStore keep everything on‑device, even in a tunnel.
Battery & performance
We profile start‑up, jank and background work, then monitor Android Vitals.
Accessibility built‑in
TalkBack labels, contrast and large‑text support are integral, not an afterthought.
Long‑term care
Signed builds, staged rollouts and steady updates as Android evolves.
Our workflow
Four clear stages, each delivering a tangible result.
Discovery
Define the problem, users and absolute no‑go rules.
Architecture
Sketch screens, data flow and permissions before any code.
Build
Write Kotlin, Compose UI and tests; ship small builds to try.
Release & care
Stage rollout on Google Play, then monitor, fix and update.
One-way data flow: the interface observes state, and the repository owns the data.
