# LOOP vs Crocodile Calendar

The clearest difference is ads: Crocodile Calendar at none against LOOP's shown. LOOP's advantage is update cadence (daily vs every 4 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

LOOP ships an update daily, Crocodile Calendar every 4 days. The most recent releases landed on October 2, 2026 and September 29, 2026 respectively.
