Weather radar and daily forecasts, with time drawn as one continuous ribbon. Live radar, storm alerts, hourly and 10-day forecasts, widgets and an AI weather assistant.
// 00 — hello, world
Small studio.
Concurrent ambitions.
CoroutineLab builds Android apps, React Native apps and websites — our own products, and products for teams who want to ship.

// 01 — about
$ cat about.md
We're a small team of mobile developers who build the apps we wish existed — and then build them for other people too.
Like a coroutine, we work on several things at once without blocking any of them: our own products on Google Play, and client apps and websites from first sketch to store listing.
// 02 — projects
$ ls ./projects
Apps we design, build and ship ourselves.
Focus Cat
A minimal, dark-mode focus app that blocks distracting apps while a cat keeps you company.
Clackulator
A calculator built like an old cash register crossed with a slot machine. The maths is a normal calculator's; the joy is all in how it feels: heavy keys, a pull lever for =, reels that land the answer, and a receipt that prints every sum.
Tip
A focus timer that turns your phone into an hourglass. Flip it to start, lay it flat to pause, shake to reset. Real sand physics, chained glasses, tags and a 52-week focus heatmap.
NurtureLog
A baby tracker built by new parents: mixed feeding, nappy alerts, vaccination reminders and multi-carer sync — for families in the UK, US, Australia and India.
// 03 — services
$ ls ./services
The same craft we put into our own apps, for yours.
$ cat android.md
Native Android apps in Kotlin and Jetpack Compose — fast, polished and built to the platform's grain, from MVP to Play Store launch.
$ cat react-native.md
One codebase for Android and iOS. Cross-platform apps that still feel native, shipped to both stores together.
$ cat websites.md
Marketing sites and landing pages for apps and studios — quick, responsive and easy to keep up to date.
