Verdict
The clearest difference is in-app purchases: Day Counter at none against OTB Clock's 1. Day Counter also leads on update cadence (daily vs every 2 weeks) and iOS requirement (13.0 vs 17.0). OTB Clock's advantage is ads (none vs shown). On price and device support there is nothing between them.
