## Description

A simple knock to check in on the people you care about.

  - Hardware-Secured Identity
  Every response is signed by a cryptographic key stored in your device's secure hardware chip (Secure Enclave).

  - One Tap, Instant Peace of Mind
  Worried about a parent who lives alone? Send a knock. If they tap back, they're okay. If they don't, you know to check in another way.
  No calls, no typing — just a tap.

  - Built for Families
  Create a group for your family or close circle. Invite members with a QR code — it takes seconds. Up to 6 people per group.

  - Simple Mode
  A single large button designed for anyone who finds smartphones overwhelming. Perfect for elderly parents or grandparents.

  Joining a group is free.
  Creating a group requires a one-time purchase.
