Independent software studio
Apps that stay on your device.
We make small, focused apps for iPhone, iPad and Apple Watch. No accounts, no subscriptions, no data collection. Download for free, pay once if you want more.
The apps
One job each, done properly.
OpenCube
Scan, solve and learn the cube.

See the shot before you take it.
Marginalia
Ask the page a question, in your own handwriting.
Punch
Bag work, counted by your watch.
TempoMaster
A steady putting stroke, from your wrist.
How we build
The same four rules in every app.
On device, always
Camera, LiDAR and motion data are processed on the phone or watch and never uploaded. Every app works in airplane mode.
No accounts
Nothing to sign up for, nothing to remember. Open the app and use it.
Pay once
Each app is free to try and has one purchase that unlocks it forever. No subscriptions, no ads, no tip jars.
Native to Apple platforms
Built with Swift and SwiftUI, using the sensors and frameworks each device already has. Fast, small and at home on your device.
