How Sona works

Tap to connect. Alert when it matters.

    Activate in the Sona app. Your pet's name stays off the tag.

  2. Finder taps

    Any phone opens the passport — photo, notes, how to reach you.

  3. You get alerted

    A scan notification when someone opens the finder page.

  4. Report missing

    One tap reaches opted-in neighbors nearby.

  5. Home safe

    Clear alerts and mark found when everyone's reunited.
