CoMon
CoMon helps you track your electricity, gas and water meters, log readings, and stay on top of your supplier contracts — all in one place.

Add devices for electricity, gas or water and keep all their identifiers and attributes in one tidy place.
Record meter readings as often as you like and watch the usage history build up over time.
Provider, contract number, pricing, run-time — always know which contract is currently active.
Daily averages and end-of-period projections help you spot anomalies before the next bill arrives.
Categories, recurring items and a yearly overview — then drill into any month to see exactly what a cost is made of.
Scroll to see every section come alive.
Your customizable overview — key stats, recent contracts and a chart per device, all in one place.
