I would give this zero stars if given that option. The description mentions your lock screen once. You don't the lockscreen has no way to permanently disable the lock screen. That is a huge strike against your app. You need to explicity state that you app requires the use of a lock screen that can't be permantly disabled. Not just a passing mention of a lock screen in a sea off repeating info in your description. The ability to disable the lock for a max of 4 hours doesn't cut it. Fix the issue.
