SaveMyTime - Time Tracker is a free time tracker app that helps you keep track of what you're doing in the moment. It's a simple time tracker for Android devices, and the best part is that it doesn't require any setup or sign in. Simply install the app, turn it on, and start tracking.

Once you start using the app, it'll start asking you what you've been doing lately. It will then give you an average time per day and per week, as well as how much time you're spending on a particular activity. You can even set a goal and track your progress.

You can also set an activity category, so you can track everything in one place. And you can add more than one activity to a single day, so you can track multiple activities at once.
