Verdict
The clearest difference is in-app purchases: Stopwatch Challenge at none against Color Hoop Stack's 1. Stopwatch Challenge also leads on ads (none vs shown) and update cadence (daily vs every 4 months). Color Hoop Stack's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 17.0). On price there is nothing between them.
