Verdict

The call

The clearest difference is review sentiment: Oxun Rowing at 100% against Spren Body Composition Scanner's 46%. Oxun Rowing also leads on monetization model (free vs free with in-app purchases) and device support (3 vs 1). Spren Body Composition Scanner's advantage is rating (4.7 vs 4.0) and ratings volume (1.5K vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Spren Body Composition Scanner holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Spren Body Composition Scanner has 1.5K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Oxun Rowing'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

Oxun Rowing ships an update monthly, Spren Body Composition Scanner every 9 days. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
