Verdict
The clearest difference is rating: 챌린저스 at 4.6 against OntoFit's 2.8. 챌린저스 also leads on review sentiment (57% vs 28%) and update cadence (every 2 weeks vs every 3 months). OntoFit's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.
