# Sixfast vs KanCN

The clearest difference is update cadence: KanCN at every 5 days against Sixfast's every 3 weeks. KanCN also leads on iOS requirement (12.0 vs 15.0). Sixfast's advantage is review sentiment (76% vs 61%) and device support (4 vs 2). On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. Sixfast sells 19 in-app purchases, starting at $5.99 per month and KanCN sells 4 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

KanCN holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 220 and 304 respectively. Written reviews complicate that: 76% of Sixfast's written reviews are positive against 61% of KanCN's, so the app with the better star average is not the one people write more warmly about.

Sixfast ships an update every 3 weeks, KanCN every 5 days. Both last shipped on September 25, 2026.
