# Flow vs KMSKA

The clearest difference is in-app purchases: KMSKA at none against Flow's 5. KMSKA also leads on rating (4.6 vs 4.1) and iOS requirement (15.0 vs 17.0). Flow's advantage is update cadence (every 6 days vs every 6 weeks) and ratings volume (7.2K vs 17). On price, ads and device support there is nothing between them.

Both are free to download. Flow sells 5 in-app purchases, starting at $3.99 per month. KMSKA asks for nothing beyond the download.

KMSKA holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Flow has 7.2K ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 24% of Flow's written reviews are positive against 0% of KMSKA's, so the app with the better star average is not the one people write more warmly about.

Flow ships an update every 6 days, KMSKA every 6 weeks. The most recent releases landed on November 4, 2026 and November 3, 2026 respectively.
