Downtime Pro

"Downtime is a fun way to challenge yourself and see how long you can last without checking your phone!

Here’s how it works:
Just use your device as you normally would. Downtime will keep track of your usage and display your top 3 records for leaving your screen off. If you don’t feel that a record should count (if you were asleep, for example), you can remove it and it will be replaced with your next best time. Compete against yourself to set new records and share on facebook and twitter to challenge your friends.
