App lock - FingerprintApplock for Android

Quick summary

App Lock — Fingerprint & Applock is a privacy utility for Android that helps you prevent unauthorized access to chosen apps and conceal sensitive files such as photos, videos, and messages. It supports biometric and code-based entry methods and includes several options to help you manage when and how apps are protected.

Protection methods available

• Use biometric verification (fingerprint) or traditional credentials (PIN or pattern) to open locked apps.
• Multiple lock modes are supported so you can pick the authentication style that fits your needs.
• Configure schedules and automatic locking rules so apps lock or unlock at times you specify.

Privacy and file hiding features

• Create a secure vault to store private photos and videos out of sight.
• Apply strong encryption to media and other files so they remain unreadable without the correct credentials.
• Restrict access to social and financial apps (for example, messaging platforms and payment apps) to keep personal data private.

Additional security functions

• The app can take photos of anyone who tries to unlock your phone with the wrong credentials.
• A disguise or stealth mode hides the app’s true purpose, helping avoid drawing attention.
• Options like temporary lock suspensions and custom lock durations give you more control over when protections are active.
• Real-time monitoring helps ensure your chosen protections stay in effect while you use the device.

How to get started

1. Install the app and set up your preferred unlock method (fingerprint, PIN, or pattern).
2. Select the apps and file types you want to protect and move private media into the vault.
3. Enable extras you want, such as intruder photos, disguise mode, or scheduled locks.

Considerations and alternative options

If you need different functionality or want a second opinion, look for other app-lock solutions that emphasize lightweight performance, strong encryption, or specialized features (for example, cloud backup for encrypted vaults or deeper integration with device security settings). Compare based on lock types offered, privacy extras, and user reviews to find the best fit for your needs.
