Calculator Lock - Photo Vault vs Weave Vault

Calculator Lock - Photo Vault is an Android privacy vault concealed behind a working calculator and opened with a 4-digit PIN. It stores photos, videos, audio, PDFs, files, and Secure Notes in encrypted app-private storage. Different PINs can open separate vaults without a visible session switcher. Users can search and pin encrypted notes, organize items in built-in folders, and restore deleted media or notes from Trash. The app displays photos, videos, audio, and PDF previews; unsupported files can be unlocked, exported, or shared. The maker describes screenshot protection and clipboard cleanup on sensitive flows. The free plan costs nothing and allows up to two personal vaults, with ads possibly appearing. There is no cloud backup or PIN recovery. Optional Intruder Detection may capture a front-camera photo after repeated failed attempts.

Weave Vault is a mobile encrypted vault for private photos, videos, PDFs, and documents, available on Android and iOS. A pattern drawn on a 5×5 grid derives the key; an unrecognized pattern opens a fresh, empty vault rather than showing an error. The app supports files up to 16 GB and includes sealed folders, duress mode, and a camera that captures directly into the vault. Its security page says AES-256-GCM seals files, thumbnails, metadata, vault manifests, and key-wrapping headers. A 12-word recovery phrase appears once when a vault is created. If both the pattern and phrase are lost, the vault cannot be recovered. Optional encrypted backup requires Pro and stores ciphertext in the user's iCloud or Google Drive; restoring does not require Pro. Sharing sends a point-in-time copy that expires within at most 30 days and can be revoked earlier. The free plan allows up to three vaults and 50 files per vault. Annual, monthly, and lifetime Pro prices are shown in the app at purchase time; the annual plan includes a seven-day free trial for new subscribers.
