Overview

• The closed beta on Apple’s TestFlight filled its 10,000-user quota hours after launch.
• All messages are end-to-end encrypted and stored only on users’ devices by default, disappearing without ever touching central servers.
• Devices form a Bluetooth Low Energy mesh that relays messages within roughly 30 meters per hop and uses bridge nodes to link clusters.
• Users can create optional group chats called “rooms” that support hashtags, password protection, and store-and-forward messaging for offline participants.
• A future update will add Wi-Fi Direct support to expand range and boost data transfer speeds.
