Lock any app and keep private photos, videos and notes encrypted. Just say your secret phrase to open them. No account, no ads, nothing uploaded.
Lock any app with your voice, and keep your private photos, videos and notes in an encrypted vault.
Voice Unlock & App Locker puts a lock screen in front of the apps you choose. To get in, just say your secret phrase. Can't speak out loud? Face ID and a 6-digit PIN are always there as backup.
APP LOCK
• Choose any apps, app categories or websites to lock
• Opening a locked app shows a lock screen. Tap Unlock, then say your phrase
• The app opens for the time you pick (1 minute to 1 hour), then locks again automatically
• Built on Apple's Screen Time framework. Your app choices stay on your iPhone
UNLOCK WITH YOUR VOICE
• Choose a secret phrase of two or more words
• Say it once during setup so the app knows your iPhone hears it
• Recognition runs on your iPhone when your language supports it (English and Vietnamese)
PRIVATE PHOTO & VIDEO VAULT
• Move photos and videos from your library into the vault
• Photos and Videos each have their own tab
• View photos full screen with pinch to zoom, and play videos inside the app
• Share a photo or video when you choose, straight from the viewer
• Optionally remove the originals from Photos afterwards
• Every item is encrypted with AES-256-GCM before it's saved
SECRET NOTES
• Keep passwords, ideas and personal thoughts in notes only you can open
• Notes are encrypted too
BUILT FOR PRIVACY
• No account, no ads, no tracking, no analytics
• Nothing is uploaded: your vault lives only on this iPhone
• The encryption key stays in your iPhone's Keychain
• The vault locks when you leave and stays covered in the app switcher
• Forgot your PIN? Reset it with Face ID or your iPhone passcode without losing anything
GOOD TO KNOW
• Voice Unlock doesn't change your iPhone's own lock screen.
• A spoken phrase is convenient, not secret from people nearby. Use Face ID or your PIN when others are around.
• Your vault is not backed up to iCloud. Deleting the app deletes the vault.
• App Lock needs Screen Time permission. You can turn it off in the app or in iPhone Settings at any time.
