ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
