Verdict
The clearest difference is rating: iChecker at 5.0 against UltraConvert's 4.0. iChecker also leads on update cadence (every 11 days vs every 6 months) and ratings volume (11 vs 1). UltraConvert's advantage is ads (none vs shown) and device support (3 vs 1). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
