# Calu vs モグダイエット

The clearest difference is update cadence: モグダイエット at every 5 days against Calu's every 11 days. モグダイエット also leads on iOS requirement (15.1 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Calu sells 3 in-app purchases, starting at $9.99 per month and モグダイエット sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Calu ships an update every 11 days, モグダイエット every 5 days. The most recent releases landed on October 17, 2026 and October 25, 2026 respectively.
