# Spren Body Composition Scanner vs AVIX

The clearest difference is rating: Spren Body Composition Scanner at 4.7 against AVIX's 4.3. Spren Body Composition Scanner also leads on ratings volume (1.5K vs 272). AVIX's advantage is review sentiment (58% vs 46%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Spren Body Composition Scanner sells 14 in-app purchases, starting at $10.49 per month and AVIX sells 13 in-app purchases, starting at $6.99 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 4.3. That said, the two scores are not equally well evidenced: Spren Body Composition Scanner has 1.5K ratings behind it against 272, so its average is the more settled of the two. Written reviews complicate that: 46% of Spren Body Composition Scanner's written reviews are positive against 58% of AVIX's, so the app with the better star average is not the one people write more warmly about.

Spren Body Composition Scanner ships an update every 9 days, AVIX every 11 days. Both last shipped on October 22, 2026.
