## What is Igloo Signer?

Igloo is a mobile companion for Frostr threshold signing on Nostr.

With Igloo, your iPhone can operate as a signing node in a threshold group. The app focuses on clear onboarding, signer visibility, and day-to-day operational safety.

Key features:
- Import credentials using QR scan or manual entry
- Run your phone as a threshold signer node
- View peers and check connectivity
- Monitor signing sessions and logs
- Use Demo Mode to explore the app without production credentials
- Store credentials on-device with platform secure storage

Important notes:
- Igloo responds to valid threshold signing requests from your peer quorum.
- Igloo does not independently initiate signatures.
- iOS uses a background audio/soundscape mechanism to keep signer processing active when the app is backgrounded.
