Verdict
The clearest difference is review sentiment: C at 100% against APECS's 18%. C also leads on rating (5.0 vs 1.7) and update cadence (every 5 days vs monthly). APECS's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price, ratings volume, ads and in-app purchases there is nothing between them.
