Coursion Studio logo
An independent software studio

Small apps,
built with care.

Coursion Studio designs and ships focused native software for Mac, iOS, and the web. On-device by default. No accounts where none are needed. Buy-once where a subscription would be greedy.

Part 02 5 apps

On iOS.

Focused mobile apps built with Expo and React Native. Small ideas, sharply executed.

Four principles. No fine print.

A handful of rules we keep returning to whenever we sit down to build something new.

01

On-device first

If a task can be done on your Mac or phone, that's where we do it. Your files, your data, your machine — no detour through a server you didn't ask for.

02

Native feel, every time

SwiftUI on the Mac. React Native and Expo on iOS, with Swift, Kotlin, and Java dropped in wherever a real platform API is the only honest answer. Whatever the stack underneath, the app on top should feel fast, quiet, and at home on the system it runs on.

03

Buy once when we can

One-time pricing wherever it makes sense. We don't put a meter on tools that should simply work — and we never charge twice for the same feature.

04

Range over a single bet

One studio, many apps — across utilities, health, lifestyle, productivity, and developer tools. Ideas worth building rarely live in one category, and shipping across them keeps the work honest.
