Filecrypt is a free Android app developed by XtrasZone that allows users to lock their files and folders quickly with high security. It offers a range of features such as fingerprint and PIN lock, 1 tap unlock, and fake crash, among others.

One of the standout features of Filecrypt is its super-fast file lock/unlock speed. It also supports folder lock, making it easy to secure multiple files at once. Users can open and share files without unlocking them, which can save time and effort.

Filecrypt provides high-security options, including fingerprint and PIN lock, and a fake login feature that won't show actual locked files and settings. Additionally, the app captures intruder selfies secretly when someone tries to log in with the incorrect PIN.

Finally, Filecrypt has no ads, making it a seamless and uninterrupted user experience. However, it does offer In-App Purchases for additional features. All locked files and folders are stored in the hidden folder: .FilecryptVault, so users should avoid deleting this folder to avoid losing their important files.

Overall, Filecrypt is an excellent choice for those who want to secure their files quickly and easily.

Please note that the developer encourages users to purchase the pro version and leave a 5-star review if satisfied with the app.
