# K vs IDOLYN

The clearest difference is iOS requirement: K at 13.0 against IDOLYN's 15.1. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. K sells 9 one-off in-app purchases and IDOLYN sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
