Your phone knows when to stay quiet.

Quiet at the right moment
Four signals. One smarter routine.
Create only the automations you need, pick the DND behavior for each one, and keep alarms or priority callers available where appropriate.
Place aware
Use a saved point or your own map keywords and radius. Android geofences help detect entry and exit in the background.
Schedule aware
Set recurring quiet windows for sleep, prayer, focused work, or any routine—with your chosen days and times.
Driving aware
Android movement signals prompt short GPS speed checks, helping Driving Mode respond without continuous GPS polling.
How it works
Set it once. Stay in control.
Smart Engine evaluates your enabled rules and changes Android Do Not Disturb only when a rule needs it.
01
Create a rule
Choose calendar, place, schedule, or driving and set its trigger.
02
Choose who can interrupt
Select Full Silent, Alarms Only, or Priority mode with the callers you allow.
03
Let Smart Engine handle transitions
DND activates for a matching situation and normal sound returns when the app-owned session ends.
Built around your choices
Automation without losing control.
Change DND yourself when plans change. Smart DND keeps app-owned automation and your manual actions separate.
Keep alarms, contacts, starred contacts, or everyone available when a Priority rule is active.
Pause automatic checks for 30 minutes, one hour, until morning, or until you decide to resume.
Local-first privacy
Your rules belong to you.
There is no Smart DND account, advertising profile, or Vianex cloud database. Rule settings and activity remain on your device. Limited location information is sent only when needed for place lookup, as explained in our policy.
