Like other dissatisfied reviewers, I should have read the reviews before buying. I thought this was an app that would "unblue" my whole phone at night. Instead it simply opens up a Google page with a yellow tint; it does not apply to my home screen or other apps. A complete waste of money and the app developers KNOW they are deceiving customers or they would have been more clear in the app description. Wish I could get my money back.
