# Spren Body Composition Scanner vs BuffMeter

The clearest difference is ratings volume: Spren Body Composition Scanner at 1.5K against BuffMeter's 7. Spren Body Composition Scanner also leads on rating (4.7 vs 4.4). BuffMeter's advantage is update cadence (every 4 days vs every 9 days). On price, ads, in-app purchases and monetization model there is nothing between them.
