Verdict
Kalkyl and MD Calculator both sit at 4.5 stars, but that hides the real split: 75% of Kalkyl's written reviews are positive against 60% of MD Calculator's. Kalkyl also leads on ratings volume (714 vs 78) and iOS requirement (15.6 vs 17.0). MD Calculator's advantage is update cadence (fortnightly vs every 5 weeks).
