The call

THOR’S TRAINING APP also leads on in-app purchases (none vs 14) and device support (3 vs 1). Spren Body Composition Scanner's advantage is rating (4.7 vs 3.7) and ratings volume (1.5K vs 3). On price, update cadence and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Spren Body Composition Scanner holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Spren Body Composition Scanner has 1.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of THOR’S TRAINING APP's written reviews are positive against 46% of Spren Body Composition Scanner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

THOR’S TRAINING APP ships an update weekly, Spren Body Composition Scanner every 9 days. The most recent releases landed on October 25, 2026 and October 22, 2026 respectively.
