ReceptionRating · Positive reviews · Number of ratings

WikEM holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: WikEM has 4.7K ratings behind it against 68, so its average is the more settled of the two. Written reviews complicate that: 63% of USPSTF Prevention TaskForce's written reviews are positive against 54% of WikEM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

USPSTF Prevention TaskForce ships an update every 3 months, WikEM every 5 days. The most recent releases landed on October 12, 2026 and October 13, 2026 respectively.
