A direct line
You talk to the people who design and write your app, not to a relay of account managers.
iOS · iPadOS · Android
Mobile apps, put into practice.
We are a compact product team that takes an app from a rough idea to a dependable release on the App Store and Google Play — and keeps it in shape long after launch day.
01 — Services
What we take on
A product built start to finish, or a specialist hand on an app you already run. Pick the part you need.
-
01
Native iOS & iPadOS
Swift and SwiftUI applications that respect Apple’s conventions, from the smallest iPhone to the largest iPad.
-
02
Native Android
Kotlin and Jetpack Compose apps, tested across screen sizes, pixel densities and the long tail of Android versions.
-
03
Product & UX design
User flows and clickable prototypes that are tried out on real devices before a line of production code is written.
-
04
Subscriptions & billing
Trials, subscriptions and one-off purchases with StoreKit and Google Play Billing — and pricing screens that are easy to read.
-
05
Quality & release
Automated and on-device testing, beta distribution, store listings and careful preparation for app review.
-
06
Long-term care
New OS versions, crash and performance monitoring, security fixes and a steady roadmap for apps already in the stores.
02 — Process
How a project runs
Four stages, each ending with something you can hold in your hand and judge for yourself.
-
01
Scope
One focused workshop: the problem, the audience, the must-have features — and what can wait for version two.
-
02
Prototype
A clickable prototype you can try on your own phone before development begins.
-
03
Build
Two-week iterations, each closing with a fresh test build and a short demo.
-
04
Release & care
Store submission, a staged rollout, then monitoring and regular updates.
03 — Stack
Two platforms, two native codebases
Each app is written in its platform’s own language and interface toolkit, so it gets that platform’s speed, look and accessibility features from day one.
| Area | Apple | Android |
|---|---|---|
| Language | Swift | Kotlin |
| Interface | SwiftUI, UIKit | Jetpack Compose |
| Purchases | StoreKit 2 | Google Play Billing |
| Testing | XCTest, XCUITest, TestFlight | JUnit, Espresso, Play test tracks |
| Accessibility | VoiceOver, Dynamic Type | TalkBack, font scaling |
| Release | App Store Connect | Google Play Console |
04 — Principles
How we like to work
Native first
Platform components and conventions before custom widgets; custom interface only where it genuinely helps.
Data minimalism
An app should collect only what it needs to work — and say so in plain words.
Goals per sprint
Every iteration starts with an agreed goal and ends with a build you can install and judge.
05 — Next step
Have an app to build — or one to rescue?
Send a few lines about it. We will come back with questions, a first plan and an honest estimate.
