Called Moment, the app can track how much you use your phone, and where you use it - and suggest when it might be time to put it away.
"I built Moment to help nudge me in the right direction by automatically tracking my daily iPhone use and giving me a warning when I'm on it for too long," wrote app creator Kevin Holesh on his blog post.
The iOS app automatically tracks how much you use your phone each day and if you are using your phone too much, you can set daily limits on yourself and be notified when you go over.
You can also set up reminders when you reach 50 percent of your alloted time, Daily Mail reported, citing Holesh's blog post.
"My goal was to find a balance of connected and disconnected that was right for me. Moment has helped me gain another 35 minutes every day to take my dogs for a hike or do a quick workout instead of mindlessly scrolling through Twitter," Holesh said.
"Moment is helping me find that balance," he added.
