The clearest difference is rating: THINKWARE iVolt at 3.7 against ANCEL BM300 Pro's 2.8. THINKWARE iVolt also leads on iOS requirement (12.0 vs 15.6). ANCEL BM300 Pro's advantage is review sentiment (37% vs 8%) and ratings volume (23 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

THINKWARE iVolt holds the better App Store score, 3.7 against 2.8. That said, the two scores are not equally well evidenced: ANCEL BM300 Pro has 23 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 8% of THINKWARE iVolt's written reviews are positive against 37% of ANCEL BM300 Pro's, so the app with the better star average is not the one people write more warmly about.

THINKWARE iVolt ships an update every 6 weeks, ANCEL BM300 Pro monthly. The most recent releases landed on October 29, 2026 and October 21, 2026 respectively.
