Verdict

Both are free to download. BMS Tool sells 1 one-off in-app purchase. EnerKey asks for nothing beyond the download.
BMS Tool holds the better App Store score, 3.9 against 3.0. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 71% of BMS Tool's written reviews are positive against 75% of EnerKey's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 16, 2026 and June 1, 2026 respectively.
