How it works
Three things to know.
-
Arm it before the crowd
Tap the big round button before the bus, the bazaar or the walk home. Lock your phone and put it away. A short buzz means it's watching.
-
Taken? It shouts
Pulled from your pocket or picked up off a table, it warns, then sounds a full-volume siren. Only your PIN, pattern or fingerprint stops it.
-
In trouble? Tap four times
With it armed, wake the screen and press volume up four times, quickly. It calls out for help, records, and texts your contacts where you are.
SOS
Four taps, and your people know.
The bus is packed and a man keeps pressing closer. You don't want to unlock your phone, find an app and type. You reach into your bag, wake the screen and tap volume up four times. By feel. Nobody sees you do it.
-
Right away, it gets loud
A shrill whistle and a voice shouting “Help! Stop it!” at full volume, even on silent (in Bangla, if your app and phone speak it). The back camera records video with sound.
-
Five seconds to change your mind
Tapped by mistake? Cancel on the screen and no message goes out.
-
Then your contacts hear from you
Up to five people you choose get an SMS with your location, plus an email if they have one. Its link opens a live map that follows you and plays the recording.
-
Unlock when you're safe
Everything stops. Stop within 15 seconds of the alert and they're told it was a false alarm.
Already sounding? If you grabbed your own armed phone and the theft alarm went off, tap 🆘 I need help on its screen, or the same four taps. It turns into an SOS, no unlock needed.
Also on the notification, a Quick Settings tile and the Home screen. The volume taps need one Accessibility switch, which the app helps you turn on.

Theft alarm
Taken from your pocket? It won't go quietly.
Rush hour at Farmgate. Someone's hand slides into your bag, and your phone is gone. But the moment it leaves your pocket, Pocket Guard knows it wasn't your fingerprint.
-
Quiet for you, loud for them
A gentle pull-out stays silent for its first second and a half, so taking out your own phone and unlocking it makes no sound. Otherwise: a warning, then the siren.
-
A siren they can't silence
Full volume through silent mode, volume buttons locked, the torch flashing and “THIS PHONE IS STOLEN” on the lock screen.
-
Photos of who's holding it
The front camera quietly takes two photos, kept in History for when you get it back.
-
A restart won't stop it
Switched off and on again, the alarm comes straight back, before anyone can unlock.
-
On the table, too
Lay it down at a café or tea stall. A slide, a lift or a tilt warns, while a bump or a cup set down doesn't.
And a few quieter helpers
- ScheduleArms itself at set times, like a Focus mode schedule. Every day 09:00–18:00, or Friday nights.
- Airplane modeTurned on while locked, the siren starts at once.
- Charger unpluggedCharging in a waiting room? Unplugged while locked, it warns.
- Earbuds disconnectYour phone walks away from your earbuds or watch: warning, then siren.
- HistoryEvery alarm with its photos, and your SOS videos to play, save or share.
Privacy
Nothing leaves your phone unless you call for help.
- No ads, no analytics. Nothing tracks what you do in the app.
- No account. No sign-up, no email, no password.
- Your photos stay yours. Intruder photos never leave the phone. They and your recordings stay in the app's private storage, out of your gallery, until you save or share them.
- SOS goes only to your people. Your location and video go to the contacts you picked and approved. The live link stops working a day after SOS ends, and the server deletes everything after 90 days. Prefer SMS only? Switch the live link off.

FAQ
Questions
Is it really free?
Yes. No price, no ads, no in-app purchases and no account.
Which phones does it work on?
Android 8.0 and newer. It needs a screen lock (PIN, pattern or password) and a proximity sensor, which almost every phone has. Some phones only report proximity while the screen is on; the Sensor check in Settings tells you in a minute. iPhone isn't possible: iOS doesn't let apps read sensors in the background.
Does it work without internet?
The theft alarm, siren, photos and SOS recording all work with no internet at all. The SOS text message needs only mobile signal, and the app retries if there's none. The live map link and the email need mobile data or Wi-Fi.
What do my emergency contacts get?
An SMS like “Nusrat needs help! SOS from Pocket Guard at 18:05. Location: …”, sent from your own number, in English or Banglish (your choice). With the live link on, it also carries a link to a map that follows you and plays the video, and contacts with an email address get it by email too. If you move, an update follows. You see and approve the exact messages when you add your contacts.
Can a thief just switch the phone off?
No app can block the power button. But if the phone is restarted during an alarm, the alarm comes back before anyone can unlock it. Many phones also have a “password to power off” setting; turn it on and the thief can't switch it off at all.
Will it go off when I take out my own phone?
Not if you unlock it. A gentle pull-out is silent for its first second and a half, so a quick fingerprint unlock makes no sound, and you have a few seconds (you choose, up to 15) before the siren. To stop it from going off at all, simply don't arm it, or let the schedule do it for you.
