Publisher Description

** SigmaUnlock Free have Adds, if you want to delete them, enjoy the launch offer! Download SigmaUnlock Gold version for just 1.99€! ** SigmaUnlock incorporates artificial intelligence technologies that check if the graphical password has been done by the phone owner or an impostor. This can be done because SigmaUnlock learns the dynamic parameters of the graphical password; i.e.: instantaneous speed, acceleration, pressure, etc.
SigmaUnlock does not compare graphs. It compares the way a person draws the graph, which is very difficult to imitate. In this way, if the graph is done by an impostor, the phone remains locked. Otherwise, SigmaUnlock unlocks the phone.
After installing SigmaUnlock, your phone will be better protected than ever, since a graphical password is much more difficult to imitate than a numeric password or pattern.
• SigmaUnlock learns dynamic characteristics of the graphical password as position, velocity or pressure stroke every few miliseconds. For this reason it is very difficult to imitate the graphical password.
• Protect your phone better than a numeric password or unlock pattern.
• Customize your unlock screen easily.
• Enjoy the app without adds (Only available in Gold and Silver versions).
• Change the graphical color and the clock color on your unlock screen (Only available in Gold version).

Advantages of SigmaUnlock Gold:
• No adds.
• Offers more customization options.
