Verdict
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.
