Mac: If you’ve ever been curious about just how much time you spend in an app, Usage is a simple little utility that will track just that.
Usage does pretty much exactly what the name suggests and that’s about it. It tracks app usage by day, showing you how much time you spend in each app. That’s it. It doesn’t dump that data into a time tracking app or cut you off when you hit too many minutes, but the data alone can be useful if you’re unclear where you’re spending (or wasting) time.
