Verdict
The clearest difference is price: OpenEvidence at Free against DermAssist's $4.99. OpenEvidence also leads on chart position (#34 vs unranked) and update cadence (weekly vs fortnightly). DermAssist's advantage is iOS requirement (13.4 vs 15.1). On ads, in-app purchases and device support there is nothing between them.
