App Lock - Applock Fingerprint

Lock private apps on a shared phone

App Lock - Applock Fingerprint adds a separate barrier to selected Android apps. It suits anyone who shares a phone, lends it to family members, or wants extra control over access to personal content. You can protect social apps, messaging, contacts, photos, payment apps and other installed software with a PIN, pattern or fingerprint.

What it protects

• Lock individual apps such as WhatsApp, Instagram, Facebook, Gallery, Contacts and Messages.
• Hide private photos and videos in a vault that is separate from the normal gallery view.
• Use relock options for leaving an app, turning off the screen or waiting for a chosen period.
• Enable protection for newly installed apps, helping you remember to secure them.

Extra privacy controls

The app can record an intruder selfie after repeated incorrect unlock attempts, giving you a record of someone trying to open a protected app. It also offers a hidden pattern path, a random keyboard and an option to disguise the app icon. A recovery email can help reset the password if it is forgotten. Some functions, including hiding files, require broad file access permission, so this is an app to review carefully against your own privacy preferences.

Grade and reach

Grade: A+ — Its 4.69 rating from 607,204 reviews places it firmly in the highest band, with a clear gap between this score and a merely adequate utility. The 100,000,000+ install count shows that Trusted Tools’ approach has reached a very large Android audience. It is a focused productivity tool rather than a general security suite: its main job is controlling access to apps and selected private media.
