Verdict

The call

The clearest difference is review sentiment: 청연 at 94% against COMMAX's 35%. 청연 also leads on rating (4.8 vs 2.0) and update cadence (every 3 weeks vs every 4 months). COMMAX's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (10.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
