# Pinarify AI vs KADROX

The clearest difference is update cadence: KADROX at every 2 days against Pinarify AI's every 4 days. KADROX also leads on iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Pinarify AI sells 6 in-app purchases, starting at $9.99 per 7 days and KADROX sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
