# ABC vs BMS

The clearest difference is rating: BMS at 5.0 against ABC's 1.8. ABC's advantage is ratings volume (24 vs 2) and iOS requirement (10.0 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.

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

BMS holds the better App Store score, 5.0 against 1.8. That said, the two scores are not equally well evidenced: ABC has 24 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 21% of ABC's written reviews are positive against 20% of BMS's, so the app with the better star average is not the one people write more warmly about.

ABC ships an update every 2 months, BMS every 6 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
