# FlowFast vs Kaiten

The clearest difference is ads: Kaiten at none against FlowFast's shown. Kaiten also leads on review sentiment (24% vs 0%). FlowFast's advantage is rating (3.4 vs 3.1) and monetization model (ad-supported vs free with in-app purchases). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

FlowFast holds the better App Store score, 3.4 against 3.1. Both are backed by a comparable volume of ratings — 5 and 8 respectively. Written reviews complicate that: 0% of FlowFast's written reviews are positive against 24% of Kaiten's, so the app with the better star average is not the one people write more warmly about.

FlowFast ships an update weekly, Kaiten every 5 days. The most recent releases landed on June 1, 2026 and September 22, 2026 respectively.
