Voice Lock: Speak to Unlock

Your private apps should be easy for you to open and harder for others to browse.

Voice Lock: Speak to Unlock lets you unlock selected apps with a spoken password. Say your secret phrase, read the four numbers shown on screen, and get back to your app. From personal chats to your gallery and email, add a layer of privacy to the apps you want to keep to yourself.

Whether you are showing someone a photo, lending your phone to a friend or sharing it with family, Voice Lock helps you keep control of what they can open.

Speak to unlock your apps

Make your voice part of your everyday app access. Choose a secret phrase, check it during setup and use it as your voice password. Each voice unlock asks you to say your phrase followed by the four numbers displayed for that attempt.

Voice Lock checks the words you say rather than identifying who is speaking, so choose a phrase you can remember and keep it private.

Choose what stays private

Use this app lock for Android to protect selected messaging, social, gallery, email and other supported apps. Choose apps individually or manage them by category, then adjust the selection whenever your needs change.

Want a gallery lock when someone borrows your phone, or an extra step before opening your messages? Protect the apps that matter to you without adding the same interruption to everything on your device.

Keep access convenient

Decide when your apps should lock again. Relock when you leave an app, or keep it unlocked for a set time so you can switch between tasks without repeating your password every time.

You can also lock apps again when your phone locks. When you are about to hand your phone to someone else, use Lock all to end unlocked sessions and restore your selected app locks.

A separate PIN when you need it

Prefer to stay quiet in public or having trouble speaking? Use your backup PIN to open a locked app. You set this PIN for Voice Lock separately from your phone's screen lock.

Your app locker gives you a choice: speak your password when it is convenient, or enter your PIN when it is not.

Know when someone tries the wrong password

See alerts for failed passphrase attempts, including which app was involved and when the attempts happened. Check recent activity from the home screen to stay aware of attempts to open your private apps.

Check your protection status

See how many apps are locked and whether protection is running. Guided permission setup explains what each permission does, while protection checks help you spot settings that may interrupt app locking, such as battery restrictions.

Voice Lock uses the microphone during voice input. Speech is processed on your phone, and the app does not save voice recordings. Offline voice unlock requires a supported speech recognition service and the appropriate language resources on your device.

Quick controls, your own style

Add a home screen widget to view your lock status, lock all selected apps or start voice unlock. Add the Lock all tile to Quick Settings for convenient access.

Personalize your voice screen with themes and wallpapers, including aurora, neon, minimal and wave styles.

Get started in a few steps

Choose the apps you want to protect, follow the permission guidance, set your secret phrase and create your backup PIN. Then speak to unlock when you need access and lock everything again when you are done.

Voice Lock protects access to selected apps and does not replace your Android screen lock. Keep your device PIN, password or biometrics enabled for phone protection.

Give your private apps an extra layer of privacy, with the convenience of opening them by voice.
