Verdict
The clearest difference is price: Time Duration/Add Calculator at Free against Scan's $0.99. Time Duration/Add Calculator also leads on iOS requirement (13.0 vs 15.0). Scan's advantage is ads (none vs shown) and update cadence (every 2 days vs every 9 months). On in-app purchases and device support there is nothing between them.
