Verdict
The clearest difference is price: Calculator⁻ at Free against 6 Timers's $0.99. Calculator⁻ also leads on update cadence (every 2 months vs every 18 months) and iOS requirement (13.0 vs 17). 6 Timers's advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
