The clearest difference is ratings volume: The Clinical Problem Solvers at 204 against MD on Call's 1. The Clinical Problem Solvers also leads on chart position (#57 vs unranked) and review sentiment (90% vs 78%). MD on Call's advantage is price ($9.99 vs $14.99) and rating (5.0 vs 4.8).

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
MD on Call costs $9.99 and The Clinical Problem Solvers $14.99 up front. Neither carries in-app purchases, so what you see is what you pay.
MD on Call holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: The Clinical Problem Solvers has 204 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 78% of MD on Call's written reviews are positive against 90% of The Clinical Problem Solvers's, so the app with the better star average is not the one people write more warmly about.
MD on Call ships an update every 4 months, The Clinical Problem Solvers every 2 months. The most recent releases landed on October 29, 2026 and October 26, 2026 respectively.
