ReceptionRating · Positive reviews · Number of ratings

Letsfit holds the better App Store score, 4.2 against 3.7. That said, the two scores are not equally well evidenced: Letsfit has 6.3K ratings behind it against 269, so its average is the more settled of the two. Written reviews complicate that: 34% of iTech Duo's written reviews are positive against 25% of Letsfit's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iTech Duo ships an update every 2 months, Letsfit every 5 weeks. The most recent releases landed on October 29, 2026 and November 2, 2026 respectively.
