Verdict
The clearest difference is in-app purchases: Shop Calc at none against Digital Simple Clock's 1. Shop Calc also leads on ads (none vs shown). Digital Simple Clock's advantage is update cadence (every 3 days vs every 11 months). On price, device support and iOS requirement there is nothing between them.
