## What is Generator Fuel & Runtime Calc?

A generator's runtime is not a fixed number. It depends on how much load
you put on it, and that changes every time someone plugs something in.

GenRun takes your generator's tank size and rated output, adds up the
appliances you are running, and tells you how many hours the fuel in the
tank is good for — and the clock time you will need to refuel.

A Live Activity puts the countdown on the Lock Screen and warns you before
the tank runs dry, so the generator stops when you choose rather than in
the middle of the night.

Fuel burn is not proportional to load. A generator at a quarter load wastes
a large share of its fuel just spinning, so the app uses a load-dependent
consumption curve rather than a flat litres-per-hour figure.

Log real refuels and the app learns your machine's actual burn rate,
which drifts from the manufacturer's figure as an engine ages.

Petrol, diesel and LPG, in litres or gallons. Everything is an estimate to
help you plan refuelling, not a guarantee. Never refuel a running or hot
generator, and follow the manufacturer's instructions. All data stays on
device and no sensor is required.
