Verdict
The clearest difference is price: Reaction Time Test at Free against SafeCracker's $0.99. Reaction Time Test also leads on update cadence (every 3 months vs every 19 months). SafeCracker's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.6). On in-app purchases and device support there is nothing between them.
