Keanwatt: Prepaid Meter Log

Prepaid electricity and water meters only tell you one number, and utility apps only sell tokens. Keanwatt tells you what that number means: how fast you are burning units, how many days you have left, and the date you will run out. Log each token you buy (what you paid and the units you got) and read the meter now and then. Keanwatt works out your average daily use from the readings, counts every top-up in between, and keeps an estimate of what is on the meter right now. A big dial shows units left against your last top-up, and a warning lights up when you are down to your last few days. • Multiple meters: home and shop, electricity (kWh) and water (m³) • Log token purchases: amount paid, units received, date • Log meter readings in seconds • Average daily burn worked out from your readings • Estimated units left now, days left and run-out date • Low-units warning before the lights go off • Cost per unit on every token, with the change since the last one • Monthly spend, monthly average and total spent • Chart of units over time with a projection to empty • Full history per meter, swipe to delete a mistake • Works with any prepaid electricity or water meter • 16 currencies including UGX, KES, TZS, RWF, NGN, ZAR, USD, EUR, GBP Works offline. No account, no ads, no tracking. Your data never leaves your phone.
