# WattWise vs Epoch X

The clearest difference is review sentiment: Epoch X at 100% against WattWise's 50%. WattWise's advantage is rating (4.3 vs 3.0) and in-app purchases (none vs 2). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Epoch X sells 2 one-off in-app purchases. WattWise asks for nothing beyond the download.

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.

WattWise ships an update every 6 weeks, Epoch X every 3 weeks. The most recent releases landed on November 14, 2026 and November 4, 2026 respectively.
