The studio

One developer.
A few apps, done properly.

Each app does one job and tries to do it well. Questions, bugs and ideas go straight to the person who builds them.

No ads, no accounts

You open the app and use it. Nothing to sign up for, and no banners between you and your data.

Your data, your iCloud

Apps keep what you enter on your iPhone and, where they sync, in your private iCloud. I can’t see it.

Built for iPhone

Widgets, Live Activities, Apple Health and the latest iOS design, used where they actually help.

Say hello.

Questions about any app, bug reports or ideas. I usually reply within two days.
