iOS app Measuring User iPhone Usage

I have a "competition" going with a friend. He's a control freak, but rather than arguing with him telling him to delegate work, I want to show him. That's where you come in. He's an app developer that chooses to do everything himself. So I want you to work on the EXACT same app he's working on. Here's the app: - Welcome screen, - statistics page The stats should measure: 1. the number of times the phone was unlocked per hour(s) / day / week 2. the length of time of the phone stayed in the unlocked position per hour(s) / day / week 3. the average time of the unlocks per hour(s) / day / week Ex, user would know that they unlocked the phone 3 times in the last hour for 3 minutes total, 1 minute average So, submit your bid and be reasonable. Thanks!
