Verdict

The call

The clearest difference is price: Medtimer at Free against Coma scales's $0.99. Medtimer also leads on review sentiment (40% vs 0%) and update cadence (every 3 months vs every 10 months). Coma scales's advantage is in-app purchases (none vs 1) and iOS requirement (9.0 vs 17.6). On ads and device support there is nothing between them.
