Great idea for an app, but it is majorly flawed. It prevents you from authenticating payments in apps as it pops up and once you've entered your fingerprint /code the authentication option has disappeared. Additionally, it was still popping up even after I removed it from banking apps. I had to uninstall it as it was making transactions unusable.

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)

Don't buy this app, it's not worth it. I disable it when at home and enable it when I go out. 50% of the time I can still open apps with it enabled when I'm out and about (all my apps are set to be locked when enabled). I always make sure it's set to enabled and apps still open. I really don't have any confidence with this, and I feel well and truly ripped off. Considering I paid £50 for it when my anti virus costs a lot less and covers multiple devices, it truly is not worth the money.
