ReceptionRating · Positive reviews · Number of ratings

Starrett System holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Dynamic Strength has 38 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 73% of Dynamic Strength's written reviews are positive against 0% of Starrett System's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Dynamic Strength ships an update every 3 weeks, Starrett System monthly. The most recent releases landed on October 13, 2026 and October 2, 2026 respectively.
