# Tani vs CK

The clearest difference is update cadence: CK at every 4 days against Tani's every 2 months. Tani's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Tani sells 6 in-app purchases, starting at $2.99 per month and CK sells 3 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Tani ships an update every 2 months, CK every 4 days. The most recent releases landed on October 24, 2026 and October 18, 2026 respectively.
