# Build and Burn vs Undefined Athletics

The clearest difference is in-app purchases: Undefined Athletics at none against Build and Burn's 7. Undefined Athletics also leads on iOS requirement (11.0 vs 16.6). Build and Burn's advantage is rating (4.9 vs 4.6) and ratings volume (293 vs 9). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Build and Burn sells 7 in-app purchases, starting at $29.99 per month. Undefined Athletics asks for nothing beyond the download.

Build and Burn holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Build and Burn has 293 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 96% of Build and Burn's written reviews are positive against 100% of Undefined Athletics's, so the app with the better star average is not the one people write more warmly about.
