How it works
Three steps, then you stop looking at your phone.
-
Pick a contact or a group
Choose the people who matter: Mom, your partner, the kids' school, or a whole group like Family or Work.
-
Give them a pattern
Use a built-in pattern, tap out your own rhythm, or turn a word into Morse code. Feel each one before you choose.
-
Feel who's calling or texting
When they call or message you, Avibrim plays their pattern. Everyone else gets a basic buzz, or nothing at all if you prefer.
Features
Made for a phone that lives in your pocket.
Everything is about telling calls apart by touch, in meetings, at school pickup, on the train or on silent.

Tap or hold the circle to record a rhythm. Touch higher for a stronger vibration.

Missed-call reminder PRO
Missed a call from someone with a pattern? A minute later, their pattern plays once more.
Skipped during calls and quiet hours
Repeat callers get through PRO
If the same person calls again within 3 minutes, it plays at full strength, even during quiet hours.
For the call at 2 a.m. that matters
Pause in one tap
Add the Avibrim tile to Quick Settings and pause for an hour. It turns itself back on.
No more "forgot to turn it on"
Share patterns by QR
Show a QR code, and a friend scans it to get your pattern. No accounts, no uploads.
Free for everyone
Quiet hours and Do Not Disturb
Pause Avibrim every night, follow Do Not Disturb, and still let starred contacts through.
Your rules, your hours
Backup, dark mode, five languages
Save patterns and assignments to a file for your next phone. Light or dark, in English, Spanish, German, Russian or Chinese.
Backup is free
Built-in patterns
Ten patterns to start with.
Each graph is the real pattern: gold is vibration, height is strength, and the length is shown in seconds.
Pulse, Swell and Ripple vary in strength. They need Pro and a phone whose motor can vary strength; elsewhere they play their plain rhythm.

Privacy
Your contacts and messages stay on your phone.
- No uploadsContacts, numbers and patterns never leave your phone. Sharing a pattern is a QR code someone scans from your screen.
- Messages: only the senderMessage vibrations look at who a new message is from, in your messaging apps' notifications. The message itself is never used, saved or uploaded. It's off until you turn it on.
- Only to pick the vibrationOn Android 10 and newer, Avibrim asks to be your caller ID & spam app. That's how Android tells it who is calling. It never blocks or rejects calls.
- No adsAvibrim is paid for by Pro, not by your attention.
Questions
Good to know.
Which phones does Avibrim work on?
Android phones running Android 7.0 or newer. Patterns with different strengths need a phone whose vibration motor can vary strength; most recent phones can, and Avibrim shows it in Settings → This phone.
Is there an iPhone version?
No, Avibrim is Android only.
Does it work when my phone is on silent?
By default Avibrim follows your ringer: on silent, it stays silent. Turn on "Vibrate on silent" in Settings and contacts with a pattern still vibrate.
Why does my phone vibrate twice?
Your phone's own call vibration can play on top of Avibrim's pattern. Turn off "Vibrate for calls" (sometimes called "Ring vibration") in your phone's sound settings. The setup guide in the app shows you where.
Why does Avibrim want to be my caller ID & spam app?
On Android 10 and newer this is how an app learns the caller's number. Avibrim uses it only to choose the right pattern. It never blocks, rejects or reports calls.
Which messaging apps work with message vibrations?
WhatsApp and WhatsApp Business, Telegram, Signal, Messenger, Viber, Google Messages and Samsung Messages. Turn it on in Settings → Messages and allow notification access. For best results, turn off the messaging app's own vibration so you feel only the pattern.
Why does Avibrim ask for notification access?
Only for message vibrations, and only if you turn them on. It's how Android lets an app see that a message arrived and who sent it. Avibrim ignores notifications from all other apps and never uses, saves or uploads what a message says.
How do I pause Avibrim for a meeting?
Add the Avibrim tile to Quick Settings (Settings → Pause from Quick Settings), then tap it. Avibrim pauses for an hour and turns itself back on. Tap the tile again to turn it back on sooner.
What happens when the Pro trial ends?
Avibrim goes back to Free. Your first 3 contacts and 3 custom patterns keep working, the rest are kept and marked Pro, and upgrading brings everything back.
I bought Pro before. How do I get it back?
Open Settings → Restore purchase while signed in to the same Google account. Pro also comes back by itself after a reinstall.
