# Fsolar vs BMS

The clearest difference is rating: BMS at 5.0 against Fsolar's 3.5. Fsolar's advantage is review sentiment (47% vs 20%) and ratings volume (37 vs 1). On price, ads, in-app purchases and monetization model 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 3.5. That said, the two scores are not equally well evidenced: Fsolar has 37 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 47% of Fsolar'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.

Fsolar ships an update monthly, BMS every 2 months. The most recent releases landed on October 13, 2026 and September 23, 2026 respectively.
