Read full descriptionHide full description
Your memo. Yours alone. LockMemo is a private, on-device encrypted vault for passwords, 2FA codes, secure notes, file attachments, and recovery seed phrases. There is no LockMemo account, no LockMemo cloud holding your vault, no ads, and no analytics or crash-reporting SDKs. ONE VAULT FOR SENSITIVE DATA • Passwords and logins with custom fields, tags, and fast search • TOTP authenticator codes with QR scanning and Google Authenticator import • Private Markdown notes • Images, PDFs, and other file attachments encrypted inside your vault • BIP39 recovery seed phrases with extra safeguards when viewing PRIVATE BY DESIGN • AES-256-GCM encryption with Argon2id key derivation • Your master passphrase never leaves your device • Works fully offline • Face ID, Touch ID, and device biometrics for quick unlock • Auto-lock, clipboard auto-clear, and app-switcher blur for sensitive views • No advertising SDKs or behavioral tracking YOUR SYNC, YOUR CHOICE By default, your vault stays on your device. Optional LockMemo Premium unlocks backup and sync through a Git repository you control—GitHub, GitLab, Bitbucket, or your own server. The Git remote—whether a hosting provider or your own server—receives only encrypted data and obfuscated file names; it cannot read your vault. Premium is a one-time purchase, not a subscription. The local vault works without it. IMPORTANT SECURITY NOTE Your master passphrase cannot be recovered. If you forget it, no one can recover your vault. Keep a safe, independent backup of your passphrase and critical recovery information. Keep your passwords, codes, notes, and private files under your control.

Verdict
The clearest difference is update cadence: LockMemo at every 2 weeks against Authenticator's every 5 weeks. LockMemo also leads on iOS requirement (16.0 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.
