ReceptionRating · Positive reviews · Number of ratings

WattWise holds the better App Store score, 4.3 against 3.0. Both are backed by a comparable volume of ratings — 4 and 5 respectively. Written reviews complicate that: 50% of WattWise's written reviews are positive against 100% of Epoch X's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency
