# Calm Cloud vs Mossi

The clearest difference is update cadence: Mossi at every 5 days against Calm Cloud's every 3 weeks. Calm Cloud's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Calm Cloud sells 10 one-off in-app purchases and Mossi sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calm Cloud ships an update every 3 weeks, Mossi every 5 days. The most recent releases landed on September 15, 2026 and September 29, 2026 respectively.
