Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

Dr.Oracle AI Medical Assistant holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Dr.Oracle AI Medical Assistant has 1.1K ratings behind it against 50, so its average is the more settled of the two. Written reviews complicate that: 74% of MRI MASTER's written reviews are positive against 56% of Dr.Oracle AI Medical Assistant's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

MRI MASTER ships an update every 2 months, Dr.Oracle AI Medical Assistant every 5 weeks. Both last shipped on October 27, 2026.
