Good idea but not recommended

this app is a great idea but it should work first try every time, or it is futile. why would i knock on my phone for five minutes when i can type my password in 5 seconds? Im tempted to ask for a refund unless they can improve this app. as of now, I DO NOT RECOMMEND IT. wasting your $
