# Weight Tracker vs Spren Body Composition Scanner

The clearest difference is rating: Spren Body Composition Scanner at 4.7 against Weight Tracker's 4.4. Weight Tracker's advantage is review sentiment (64% vs 46%) and device support (4 vs 1). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Weight Tracker sells 13 in-app purchases, starting at $4.99 per month and Spren Body Composition Scanner sells 14 in-app purchases, starting at $10.49 per month. Whichever you choose, the download price is not the number that matters.

Spren Body Composition Scanner holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 1K and 1.5K respectively. Written reviews complicate that: 64% of Weight Tracker'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.

Weight Tracker ships an update weekly, Spren Body Composition Scanner every 9 days. Both last shipped on November 1, 2026.
