For curbing a smartphone addiction
Moment tracks the time you spend on your iPhone or iPad each day and reminds you every time you log another hour. The $4 premium version enables you to set daily time limits, while Moment Family ($45 a year) lets you track and limit your kids’ screen time.
Mute is a newer iOS app that works a lot like Moment, though its timekeeping is less dependable—and it’s “all too eager” to shame you for being online too long, even when it’s wrong. It will congratulate you, though, when you manage to go phone-free for long periods.
Forest emphasizes positive reinforcement, which seems a better way to go. Each time you launch the app—and thus stay off others—it grows a virtual tree on your screen for as long as you leave the phone idle. Stay off your phone long enough and an entire digital forest will bloom.
