Verdict
The clearest difference is rating: Derm DDx at 4.3 against Clinical Guidelines's 3.7. Derm DDx also leads on update cadence (every 5 months vs every 38 months) and iOS requirement (15.0 vs 17.0). Clinical Guidelines's advantage is in-app purchases (none vs 1). On price, ratings volume, ads and device support there is nothing between them.
