Most Unix timestamp tools are buried in a browser tab or wrapped in Electron. UnixTime is a native macOS app for the menubar that does one thing well: convert timestamps, fast & easy. Built-in timestamp math, full conversion history, unlimited custom formats with drag & drop ordering. No account, no subscription, no in-app purchases. Buy once, use on all your Macs. For developers who open a timestamp converter a dozen times a day and just want the answer immediately.
