SayLatch: Voice Lock Screen

SayLatch adds its own lock screen to your Android phone and opens it with a phrase you choose. Keep a PIN, pattern or fingerprint ready for quiet places, and give the lock screen a look that fits you.

Voice unlock
Pick a short phrase and say it during setup. When the SayLatch lock screen appears, tap the mic and say your phrase to open it. You can pick from 36 recognition languages. SayLatch uses the speech recognition service on your phone, so the languages that work depend on that service. Unclear speech does not count as a wrong try.

You can add more than one voice and pick the active one. Turn on Listen when the screen turns on, and the mic starts as soon as the lock screen appears, so you can speak without tapping.

Optional AI check
Basic voice mode checks that you said the right phrase. It does not check who is speaking. Turn on AI check when you want more: after a one-time model download, you record three short phrases, and from then on SayLatch compares both the phrase and your voice. AI check runs offline on your phone and is available in 11 languages: English, Spanish, Portuguese, French, German, Italian, Dutch, Polish, Russian, Turkish and Vietnamese.

Other ways to unlock
• PIN with 4, 5, 6 or 8 digits
• Pattern on a 3×2, 3×3, 4×4 or 5×5 grid
• Fingerprint on supported devices
• Recovery question to get back in and reset a forgotten PIN, pattern or phrase

From the fifth wrong try, the lock screen asks you to wait 30 seconds, and 30 seconds more for each further wrong try.

Make the lock screen yours
• 12 wallpapers in three sets: Waves, Fields and Places
• 6 lock styles, each with its own colors
• Your own photo from the gallery, cropped to fit
• Preview a look with voice, PIN or pattern before you apply it

Clear about how it works
SayLatch shows its own lock screen on top of other apps when your screen turns off. It does not replace Android's lock screen, so keep your phone's screen lock on for full protection. SayLatch needs microphone access and permission to display over other apps. Notifications tell you when the lock screen is on or paused.

The app is available in 16 languages, including English, Spanish, Portuguese, French, German, Hindi, Japanese, Korean, Arabic and Chinese.
