Verdict
The clearest difference is in-app purchases: Calculator with reverse screen at none against HourChime's 1. Calculator with reverse screen also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (15.8.3 vs 17.0). HourChime's advantage is ads (none vs shown). On price and device support there is nothing between them.
