# CassoFlow vs muse

The clearest difference is ads: CassoFlow at none against muse's shown. CassoFlow also leads on update cadence (weekly vs every 3 weeks). muse's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.6). On price and in-app purchases there is nothing between them.

Both are free to download. CassoFlow sells 3 in-app purchases, starting at $1.99 per month and muse sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CassoFlow ships an update weekly, muse every 3 weeks. The most recent releases landed on November 8, 2026 and November 6, 2026 respectively.
