Android‑only studio

We build native Android apps, but never send data off‑device

chemothu.com crafts offline-first Android apps in Kotlin and Jetpack Compose. No trackers, no advertising ID, no hidden behavior after install.

Our work

From initial concept to ongoing updates on Google Play.

  1. Native Android apps

    Kotlin from day one. Apps run smoothly on modest hardware.

  2. Compose interfaces

    Declarative UI with Material 3, adaptive layouts and purposeful motion.

  3. Offline data handling

    Room and DataStore keep everything local, so the app works in a tunnel or on a plane.

  4. Battery and performance

    We profile startup, jank and background work, then monitor Android Vitals after each release.

  5. Accessibility

    TalkBack labels, proper contrast and large‑text support are built in.

  6. Release & care

    Signed builds, staged rollouts on Google Play and regular updates as Android evolves.

How we work

Four stages, each delivering a tangible outcome.

  1. Discovery

    Define the problem, target users and absolute limits.

  2. Architecture

    Sketch screens, data flow and permissions before coding.

  3. Build

    Kotlin, Compose and tests, delivered in incremental builds for testing.

  4. Release & care

    Staged rollout on Google Play, then monitoring, fixes and updates.

One-way data flow: the interface observes state, and the repository owns the data.
