StayFree is an excellent time optimization tool if you want to manage the time you spend on your smartphone. Specifically, you can control how much time you spend on each of the apps you have installed.
StayFree is especially useful if you feel that you spend too much time on your smartphone or simply want to track how much time you spend on each app. StayFree tracks the time you spend with an app open. It also tracks how many times you unlock your Android smartphone, as well as how many times you turn it on. On the other hand, this tool tells you the average amount of time people spend on each app, so you can see if you're above or below average. It also tells you if you've reduced the time you spend on each app, and finally, it lets you create alarms that warn you when you've spent more time than you intended on a particular app.
Another feature StayFree offers is a breakdown of the type of information you spend your time on by category. Basically, it classifies your apps into entertainment, utilities, education, social networks, health and fitness, and system apps. The point is to give you a clear idea of how much time you spend on each thing and, if you don't like the result, to help you change your habits.
StayFree is a good app for detoxing from your smartphone and reducing your screen time, or at least better understanding how you spend that time.
