Diesel Boss runs the pump on your farm tank. It measures every fill, films it and keeps the record, so nobody on the farm has to write anything down.
In development

Tag in and the valve opens. The pump runs, the meter counts, the camera records. Pull the nozzle and the fill closes as a record with a name on it. Try it.
A simulation of the sequence. Example figures.
Enrol your drivers and map who may refuel which machines. They tag in, they pull, and it is on the log with their name on it.
Footage is stored against the fill's log entry. When a machine's consumption looks wrong, go and look.
The diesel cart carries a tag and a level sensor. What went in is checked against what came out, and an alert is raised when they disagree.
Out of reception, Diesel Boss keeps every record on the unit and syncs to your phone over Bluetooth.
Interface concept. Example figures.

What we are working on now. Pilot farms help us shape it.
We are testing on our own farm until the hardware is up to scratch. After that, a handful of pilot farms close enough to Dundee to drive to. You run it, we build the next version with you.
Diesel Boss is in development. Nothing is on sale yet. App screens are concepts.
