What's the best Android app for securing private photos with a password?

Gallery is an Android application specifically built for users who need to protect their personal media from prying eyes. It allows individuals to lock photos and videos behind a secure password, PIN, or pattern, ensuring that sensitive content remains private even if the device is shared. The app features a hidden vault that isolates media from the main gallery, making it invisible during casual browsing. Real-world scenarios include securing intimate images on a family-shared tablet or preventing coworkers from accidentally viewing private files during presentations. Users report that the interface is intuitive, with drag-and-drop functionality for quickly moving items into the vault. Some reviews highlight the decoy password option, which displays a fake gallery to misdirect unauthorized access attempts. However, a few users note that the app can experience minor lag when processing large batches of files, and occasional sync errors with cloud backups have been mentioned. Despite these quirks, Gallery's consistent performance in safeguarding data makes it a reliable choice for photo privacy. The inclusion of backup and restore features adds value for those concerned about data loss, though a stable internet connection is recommended for optimal use.
