Three numbers, kept honest

Every appliance you add is tracked at the unit that matters for it.

kWh

Scan the label, skip the typing

Point your camera at the barcode or the energy label and WatchYourWatts pulls in the appliance's power rating for you.

p / kWh

Costs that move with your tariff

Set your unit rate once. Running costs recalculate whenever your rate changes, so the figures never go stale.

£ / month

A monthly target you can hold

Choose what you want to spend. Track it daily. Get a nudge while there's still time to do something about it, not after the bill arrives.

Start with one appliance

Add the thing you suspect is costing you the most. You'll know in a minute whether you're right.
