Verdict

The call

The clearest difference is price: Spren Body Composition Scanner at Free against Bar Path's $4.99. Spren Body Composition Scanner also leads on rating (4.7 vs 3.0) and ratings volume (1.5K vs 5). Bar Path's advantage is in-app purchases (none vs 14) and chart position (#185 vs unranked). On review sentiment, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Spren Body Composition Scanner holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Spren Body Composition Scanner has 1.5K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 50% of Bar Path'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

Bar Path ships an update fortnightly, Spren Body Composition Scanner every 9 days. The most recent releases landed on September 6, 2026 and September 19, 2026 respectively.
