Truskawka - Offline Bluetooth Messenger
Private peer-to-peer messaging over Bluetooth for places where Wi-Fi and cellular data are unavailable or overloaded.
Offline-first Bluetooth messaging
Truskawka connects nearby devices directly over Bluetooth. No Wi-Fi, no cellular data, no cloud relay, and no servers in the message path.
How it works in 3 steps
Download the app without registration or a phone number, enable Bluetooth, and start chatting with people nearby.
