# iO vs Climb Fling

The clearest difference is rating: Climb Fling at 4.6 against iO's 3.7. Climb Fling also leads on ratings volume (647 vs 19). iO's advantage is ads (none vs shown) and update cadence (every 6 weeks vs every 14 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. iO sells 1 one-off in-app purchase and Climb Fling sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Climb Fling holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Climb Fling has 647 ratings behind it against 19, so its average is the more settled of the two. Written reviews split almost evenly too, at 71% and 71% positive.

iO ships an update every 6 weeks, Climb Fling every 14 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
