Got this app when I started getting worried my two-year-old was getting too good with my phone... sometimes you just want to fool around with your sig other and not have it pop up by accident when your kid presses the wrong button, or when you carelessly let your coworker scroll through baby pictures on your phone "oohing" and "awwing" until something else actually makes them actually pause :-D
Used it for a month now. Very intuitive, easy to use, and no BS so far, and gives peace of mind to career-conscious perverts and responsible but horny parents!
