Native Android studio

Hand‑crafted tiny Android utilities that run locally on your phone

At HENRI'S LTD we build offline‑first Android tools in Kotlin and Compose. No trackers, no ad IDs, no hidden behaviour after install.

What we build

Full‑cycle Android utilities, from sketch to release, with the boring bits handled correctly.

Native Android utilities

Kotlin from day one. Small tools that feel at home on any Android device.

Compose‑based interfaces

Declarative UI using Material 3, adaptive layouts and smooth motion.

Local‑first data

Room and DataStore keep everything on the device, so the app works anywhere.

Battery‑aware performance

We profile start‑up, jank and background work, then monitor Android Vitals.

Built‑in accessibility

TalkBack labels, high contrast and scalable text are included from the start.

Release & maintenance

Signed builds, staged rollouts on Google Play and ongoing updates.

How we build

Four clear steps from first call to long‑term support. Each stage leaves a tangible output.

  1. Discovery

    We define the problem, target users and hard limits.

  2. Architecture

    We sketch screens, data flow and permissions before any production code.

  3. Build

    Kotlin, Compose and tests delivered in small installable builds.

  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.

Tools we trust

A compact, plain toolbox that keeps our apps maintainable.

Kotlin

Concise, null‑safe Kotlin code that's easy to review.

Coroutines & Flow

Coroutines & Flow for clean async and state handling.

Jetpack Compose

Jetpack Compose for adaptive, declarative screens.

Room

Room provides a typed local database for offline storage.

WorkManager

WorkManager runs reliable background jobs within battery limits.

Hilt

Hilt supplies testable dependency injection.

Gradle CI/CD

Gradle CI/CD guarantees repeatable builds and checks.

Play Console

Play Console handles staged rollouts and vitals.

What we promise

Four non‑negotiable rules for every project.
