ReceptionRating · Positive reviews · Number of ratings

Function Health holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Function Health has 25K ratings behind it against 149, so its average is the more settled of the two. Written reviews complicate that: 81% of 5Strands's written reviews are positive against 62% of Function Health's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

5Strands ships an update every 5 days, Function Health weekly. The most recent releases landed on September 29, 2026 and October 2, 2026 respectively.
