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)

DO NOT INSTALL, I REPEAT, DON'T NOT INSTALL. Lately, due to using the free version, damn, it has become a nuisance of an app: showing ads I could not remove from the screen, sequence of opening WhatsApp is horrible. You get a video calling, you have to unlock to accept the call, then unlock WhatsApp itself, then find out that your video call has shrunk, you can't maximise. Monthly subscription is unreasonable for the function it performs.
