Fuming! I've had the paid ad free version of this app for over 2 years, and now, all of a sudden, there are ads everywhere, and it's become a subscription service. That is beyond ridiculous that someone can pay full price for a service, and then it's completely changed. I don't understand why previously paid ad free accounts were not left as such. Will be deleting and DO NOT RECOMMEND!!!!

Downloaded this to fingerprint lock individual apps. It worked great for months, did exactly what I wanted it to do, however, it has since started asking me to "boost", and the "spy camera" although a great idea, goes off with a notification every single time I unlock my phone even though the app is recognizing my fingerprint & unlocking... A very frustrating experience given that it was a great app before the update.

Awesome app! It's definitely free and easy to use (despite the premium version)! Definitely recommend it. Though, I only wish to have more fake app icons OR be able to upload one and change the name, as well as more natural fake error messages (an error message that looks like a standard error message depending on phone model)
