Not worth it
When you have the app activly recording, it will show a red bar across the top of your iPhone the entire time.
You have to pay 99 cents for the app and it will give you the ability to save the last minute of "what just happened". If you want the full 5 minutes itll cost you another 4.99. I understand this company has to make money, but that is asking way too much for something that is disruptive (red bar). I would say it would be reasonable to make this app free with one minute of recording and the 4.99 option for the full unlock, OR 99 cents for the full 5 minutes since you cant download it for free and you probably wont want to buy it after you see that red bar. At least you wont be upset about wasting a dollar.
