ResQMesh
Radio mesh for emergencies
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Network key and encrypted private messages for 868 MHz boards. In an emergency, call 112 first: ResQMesh supports your team where there is no coverage.
ResQMesh lets a team keep in touch where there is no mobile coverage. Your iPhone connects over Bluetooth to a small LoRa radio board, and the boards pass messages, positions and ALERTs from one to another, building a mesh with no network, no SIM and no Internet.
IN AN EMERGENCY, CALL 112 FIRST
Or your local emergency number. ResQMesh is a support to communications, not an emergency service, and must not be your only way to ask for help. Messages, positions and ALERTs depend on terrain, batteries and on other boards being in range and switched on: delivery is not guaranteed.
THE ALERT
Hold the ALERT button for three seconds: your position goes to every board on the mesh, and your board repeats it until another board confirms it. You see who confirmed, and the others see where you are, with distance and direction. The ALERT is always free: you can send it, receive it and confirm it without a licence. It can also start from the Action button, from Shortcuts and from the Apple Watch.
FREE, WITHOUT A LICENCE
- The ALERT, sent, received and confirmed
- APRS on 433 MHz: beacons, APRS messages and the stations your board hears, also on the map
WITH THE YEARLY LICENCE
- Channels and private chats, with delivery confirmation and ready replies
- Encryption on 868 MHz: network key and private messages encrypted by the app
- The team on the map and in the network list, with how each board was heard
- The network profile as a QR code: the whole team on the same radio settings, channels and network key in a few seconds
- The channel check, to choose a quiet frequency before going out
- LoRa APRS stations around you from the Internet
- Apple Watch, CarPlay and Siri: read and send messages, follow an ALERT
ENCRYPTION ON 868 MHz
The team leader creates a network key and shares it with the network profile: the boards encrypt channels, private messages and positions, and boards without the key cannot read them. Private messages can also be encrypted by the app for the operator they are written to. ALERTs and Emergency-Net always stay in clear, so that anyone in range can read them. On 433 MHz encryption is not allowed and everything travels in clear.
MADE FOR THE FIELD
- Works with the phone locked: notifications, Live Activity on the Lock Screen and in the Dynamic Island
- Widgets for the board, active ALERTs and unread messages
- History synchronised with iCloud between your devices, with private messages kept encrypted
- The user guide is inside the app and can be read with no network
- English and Italian, following the language of your iPhone
- Try it without a board: the demo board shows the whole app with simulated traffic
