# BMS vs Buknuwo

The clearest difference is rating: BMS at 5.0 against Buknuwo's 1.7. Buknuwo's advantage is update cadence (fortnightly vs every 6 weeks) and review sentiment (29% 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 1.7. Both are backed by a comparable volume of ratings — 2 and 7 respectively. Written reviews complicate that: 20% of BMS's written reviews are positive against 29% of Buknuwo's, so the app with the better star average is not the one people write more warmly about.

BMS ships an update every 6 weeks, Buknuwo fortnightly. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
