# EVSEMaster vs B

The clearest difference is review sentiment: B at 67% against EVSEMaster's 23%. B also leads on ratings volume (57 vs 4). EVSEMaster's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 7). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. B sells 7 in-app purchases, starting at $0.99 per month. EVSEMaster asks for nothing beyond the download.

EVSEMaster holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: B has 57 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 23% of EVSEMaster's written reviews are positive against 67% of B's, so the app with the better star average is not the one people write more warmly about.

EVSEMaster ships an update every 5 weeks, B monthly. The most recent releases landed on October 15, 2026 and October 23, 2026 respectively.
