Verdict

The call

The clearest difference is review sentiment: Guide Dose at 86% against MedCalX's 46%. Guide Dose also leads on update cadence (every 5 days vs every 5 months) and iOS requirement (15.5 vs 17.0). MedCalX's advantage is monetization model (free with in-app purchases vs subscription). On price, ads, in-app purchases and device support there is nothing between them.
