# ioio vs Kristoon

The clearest difference is rating: ioio at 4.8 against Kristoon's 3.0. ioio also leads on ads (none vs shown) and ratings volume (25 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ioio sells 6 one-off in-app purchases and Kristoon sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ioio holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: ioio has 25 ratings behind it against 1, so its average is the more settled of the two.

ioio ships an update every 4 days, Kristoon fortnightly. The most recent releases landed on August 15, 2026 and August 3, 2026 respectively.
