LockMyPix vs Obscura Photo Vault

LockMyPix is a mobile vault for photos, videos, documents, and other files on Android and iOS. The maker says imported files are encrypted with AES CTR in real time and kept on the device or an SD card rather than sent to its servers. For backup, LockMyPix Cloud can transfer files to the user's Google Drive or Dropbox account. Access can be protected with a password, PIN, pattern, fingerprint, or face unlock; face unlock depends on the device. The vault supports unlimited videos, including 8K video, and unlimited folders and subfolders. Premium features include a decoy vault, app disguise, intruder selfies, and SD-card storage. Free Basic Protection costs nothing, includes ads, and leaves some features to Premium. LockMyPix Premium costs $29.99, paid once and removes ads while unlocking premium features. The iOS listing requires iOS 15 or later; Mac support is listed for macOS 12 or later on an Apple M1 chip or later.

Obscura Photo Vault stores photos and videos in encrypted vaults on iOS. It uses AES-256-GCM and derives vault keys with 600,000 rounds of PBKDF2-HMAC-SHA256. The maker says the app functions without network access, has no server or account system, and gathers no installation, usage, or analytics data. It provides ten encrypted vault slots, Face ID and Touch ID unlocking, configurable auto-lock, delays after failed attempts, and memory clearing when a vault locks. Photo tools include editing, collages, tags, favorites, manual arrangement, duplicate detection, and Live Photo frame extraction. Users can import from their camera roll and export a vault as a password-protected encrypted.obscura file. Vault data is included in iCloud Backup by default and remains encrypted there. The maker says the indistinguishability property for hidden vaults applies only within stated threat-model bounds. The free plan allows up to 50 photos in one vault. Pro Monthly is $6.99 a month; Pro Yearly is $29.99 a year after a 7-day free trial; Pro Lifetime is $39.99, paid once payment. Forgotten passwords cannot be recovered.
