Apps

Small, focused iPhone tools that run entirely on your device.

No accounts. No logins. No analytics, advertising, or tracking. Anything you create stays on your phone, or in your own private iCloud where HeadBartender syncs between your devices. None of them send anything to us — barcode recognition in HeadBartender runs against a database built into the app, so a scan never leaves your device. This is described on its page and in the Privacy Policy.
