Verdict

The call

The clearest difference is monetization model: Days Matter Air at free with in-app purchases against OnClock's subscription. Days Matter Air also leads on ratings volume (335 vs 1) and iOS requirement (12.0 vs 18.0). OnClock's advantage is update cadence (every 11 days vs every 2 months) and rating (5.0 vs 4.7). On price, ads, in-app purchases and device support there is nothing between them.
