Both are free to download. Muscle & Motion sells 3 in-app purchases, starting at $15.00 per month and FlexiTrace Posture Analysis sells 9 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Muscle & Motion holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Muscle & Motion has 681 ratings behind it against 31, so its average is the more settled of the two. Written reviews complicate that: 77% of Muscle & Motion's written reviews are positive against 83% of FlexiTrace Posture Analysis's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Muscle & Motion ships an update monthly, FlexiTrace Posture Analysis every 10 days. The most recent releases landed on November 6, 2026 and November 12, 2026 respectively.
