# EE vs BMS

The clearest difference is rating: BMS at 5.0 against EE's 1.8. EE's advantage is ratings volume (9 vs 1) and iOS requirement (11.0 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: EE has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 13% of EE's written reviews are positive against 20% of BMS's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 4, 2026 and September 23, 2026 respectively.
