# SwiftFlow vs SMART BMS

The clearest difference is update cadence: SMART BMS at every 6 weeks against SwiftFlow's every 5 months. SMART BMS also leads on rating (2.1 vs 1.8) and ratings volume (76 vs 6). SwiftFlow's advantage is review sentiment (20% vs 11%) and iOS requirement (9.0 vs 11.0). 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.

SMART BMS holds the better App Store score, 2.1 against 1.8. That said, the two scores are not equally well evidenced: SMART BMS has 76 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 20% of SwiftFlow's written reviews are positive against 11% of SMART BMS's, so the app with the better star average is not the one people write more warmly about.

SwiftFlow ships an update every 5 months, SMART BMS every 6 weeks. The most recent releases landed on June 1, 2026 and September 14, 2026 respectively.
