Native Android studio

Hand‑stitched Android apps that only use what they need

At TYMCK we build every app the same way: offline‑first, no trackers, no advertising ID, and careful attention to detail.

Our stack

Standard, well‑supported tools – nothing exotic, easy to hand over.

Kotlin

Kotlin – concise, null‑safe code that’s easy to review.

Coroutines & Flow

Coroutines & Flow – smooth background work and state handling.

Jetpack Compose

Jetpack Compose – adaptive, declarative UI for phones and tablets.

Room

Room – typed local database for offline storage.

WorkManager

WorkManager – reliable jobs that respect battery limits.

Hilt

Hilt – dependency injection that keeps modules testable.

Gradle CI/CD

Gradle CI/CD – repeatable builds and checks on every change.

Play Console

Play Console – staged rollouts, vitals and release tracking.

Our work

From an empty repo to a maintained release on Google Play.

Native Android apps

Kotlin from day one. Apps feel at home on Android and run smoothly on modest devices.

Compose interfaces

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

Offline data handling

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

Battery and performance

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

Accessibility first

TalkBack labels, high contrast and large‑text support are built in, not added later.

Long‑term care

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

Our process

A short, predictable path from idea to released app.

  1. Discovery

    We define the problem, target users, and strict limits on app behaviour.

  2. Architecture

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

  3. Build

    Kotlin, Compose and tests delivered in small builds you can install and try.

  4. 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.

FAQ

Short answers about how we work.

What does TYMCK do?

TYMCK designs, builds and maintains native Android apps, focusing on offline use and user privacy.

Which platforms do you support?

Android only. We go deep on one platform instead of spreading thin.

What do you do with user data?

Our apps keep data on the device. We do not run analytics or ad SDKs, and we do not sell data.

How can I contact you?

Write to tuqokirafo575@gmail.com or use the contact form on this page.

Do you support apps after release?

Yes. We ship fixes, adapt to new Android versions and keep dependencies current.

Where we don't compromise

What stays the same across every app we build.

Zero tracking by design

We add no analytics, ad SDKs or fingerprinting.

On‑device by default

All data is processed and stored on the phone.

Battery discipline

Background work and wake‑ups are measured and kept minimal.

Accessible interfaces

Screens work with TalkBack, large text and sensible contrast.
