CalcuLuz

CalcuLuz es una aplicación sencilla y fácil de usar, que te permitirá llevar adecuadamente un historial de lecturas de tu medidor de luz, para que sepas con exactitud la cantidad de kWh que has consumido dentro de un periodo de tiempo determinado. De igual forma, podrás ir agregando las lecturas de tus recibos de la CFE para saber hasta que fecha se esta contabilizando el cobro de tu consumo y que puedas compararlo con tus lecturas individuales para evitar posibles errores que existan del lado de comisión. Si tienes un sistema fotovoltaico (paneles solares) con interconexión a la red de CFE (medidor bidireccional), esta aplicación te permitirá saber con exactitud la cantidad real de kWh que se cobrarán en tu próximo recibo al momento de la lectura. Esto es muy útil para detectar problemas con la eficiencia de nuestro sistema generador de electricidad y saber si éste funciona adecuadamente.

Verdict
The clearest difference is in-app purchases: CalcuLuz at none against iDOCTOR's 1. CalcuLuz also leads on iOS requirement (9.2 vs 15.6). iDOCTOR's advantage is update cadence (monthly vs every 2 months). On price, ads and device support there is nothing between them.
