ReceptionRating · Positive reviews · Number of ratings

IDSA Practice Guidelines holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: IDSA Practice Guidelines has 559 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 0% of IDSA Practice Guidelines's written reviews are positive against 57% of ACP MKSAP's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

IDSA Practice Guidelines ships an update every 7 months, ACP MKSAP every 10 days. The most recent releases landed on September 23, 2026 and September 14, 2026 respectively.
