# SRNE vs BMS

The clearest difference is rating: BMS at 5.0 against SRNE's 4.2. SRNE's advantage is update cadence (fortnightly vs every 2 months) and review sentiment (40% vs 20%). 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 4.2. That said, the two scores are not equally well evidenced: SRNE has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 40% of SRNE'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.

SRNE ships an update fortnightly, BMS every 2 months. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
