# Spren Body Composition Scanner vs Autus

The clearest difference is review sentiment: Autus at 100% against Spren Body Composition Scanner's 46%. Autus also leads on rating (5.0 vs 4.7). Spren Body Composition Scanner's advantage is ratings volume (1.5K vs 6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Spren Body Composition Scanner sells 10 in-app purchases, starting at $10.49 per month and Autus sells 5 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Autus holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Spren Body Composition Scanner has 1.5K ratings behind it against 6, so its average is the more settled of the two.
