Although it is draining the battery, it constitutes a good alternative to Norton and Samsung secure folder if you are using a Fairphone 5 (and cannot use these two app). It also seems to respect privacy (by comparison to other apps on the market).

Great app - simple, yet locks all you want locked, including Settings. Totally worth it. BUT: 1) In Samsung Note 9, if you lock Settings, Samsung Secure Folder fails. You must choose 'tween that & this app. I choose the app, coz SSF doesn't lock Settings. 2) Contacts has 2 access points - the Contacts icon, and the Contacts tab in the Phone app. When Contacts is locked, only the icon access is locked - access via tab in Phone is open 3) Hope you can include Password access - more secure

Not very impressed with this app lock. The fingerprint feature is nice and also very necessary because I'm constantly having to unlock an app with it- even if I've just used the app. Other lock apps have a feature that permanently unlocks a just used and unlocked app until the screen is shut off (at which point they'll lock again). Biggest con is that this app likes to close randomly by itself so all previously locked apps are now unlocked until you go back into this lock app and reset it again.
