The feedback board is the best place — post it once, I read every one, and you can watch its status change from open to fixed.

For anything private — a licence question, or something you'd rather not post publicly — just drop me a line.

Every app is open source. File an issue or just see how it works.
02 Common questions
Installing an app
Download the .dmg from the app's page, open it, and drag the app into your Applications folder. The apps are notarized by Apple, so they open without an "unidentified developer" warning.
Getting updates
Most apps check for their own updates and offer to install them. You can also re-download the latest build from the app's page at any time.
System requirements
Each app's page lists the macOS version it needs near the top — have a quick look there before downloading.
Privacy
No accounts, no analytics, no tracking. The apps do their work on your Mac, and this site doesn't follow you around. The Imprint has the legal details.
What does it cost?
Nothing. Every app here is free — no ads, no paywalls. If one saved you time, a tip is always welcome but never expected.
Uninstalling
Quit the app and drag it from Applications to the Trash. No background services, no login items left behind.
