GPS & fleet tracking
Trackers connected over MQTT, live map, trip playback, geofences and vehicle telemetry such as ignition, speed and battery.
When your software has to work with real devices.
Most of our systems don't stop at the screen. We connect software to the hardware it depends on: 4G GPS trackers streaming over MQTT to a live fleet dashboard, Bluetooth ESC/POS receipt printers and cash drawers at the till, camera barcode scanning, tills that pair with each other over Bluetooth and Wi-Fi Direct, and Android phones or PCs running as local servers so a site keeps working offline.
What we deliver
Point-of-sale hardware
Bluetooth ESC/POS receipt printers, cash drawers and camera barcode scanning on Android tills.
Device-to-device sync
Tills and tablets that find each other over Bluetooth LE and sync over Wi-Fi Direct when there is no internet.
Offline hubs
An Android phone or Windows PC acts as the local server for a school, shop or field team and syncs to the cloud later.

Frequently asked questions
Can you build GPS tracking for our vehicles?
Yes. We have built fleet tracking on 4G GPS trackers that report over MQTT, with a live map, trip playback, geofences and telemetry dashboards.
Do you supply the hardware?
We help you choose suitable devices (trackers, printers, scanners, tablets) and integrate them with your system.
