Smartphones have long become our personal assistants. We trust them a lot of our personal information. We cannot do without them in many aspects of our lives. The smartphone has become an intermediary in such issues as work and business, communication with friends and relatives, personal hobbies, etc. Our desire to protect our privacy is natural. Fortunately, the phone’s functions allow you to do this with passwords, PIN-codes, lock patterns, etc. Moreover, you can protect a specific app by setting fingerprint protection on it. This is convenient in many moments, for example, when you give your phone to another person and worry that they can open something they shouldn't. Better safe than sorry.

This app provides you with many options, themes, and personalizations. For example, you can lock not only the apps but also Bluetooth or the screen of recently used apps

LoCKit - Pattern, PIN or Fingerprint Unlock
This app protects your files, photos, and videos. Keep in mind that you will have to face ads that will appear every time you unlock an app
