# Rebuild Training vs Functional Bodybuilding

The clearest difference is in-app purchases: Functional Bodybuilding at none against Rebuild Training's 3. Functional Bodybuilding also leads on rating (2.9 vs 2.6) and ratings volume (146 vs 8). Rebuild Training's advantage is review sentiment (40% vs 26%) and device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.

Both are free to download. Rebuild Training sells 3 in-app purchases, starting at $29.99 per month. Functional Bodybuilding asks for nothing beyond the download.

Functional Bodybuilding holds the better App Store score, 2.9 against 2.6. That said, the two scores are not equally well evidenced: Functional Bodybuilding has 146 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 40% of Rebuild Training's written reviews are positive against 26% of Functional Bodybuilding's, so the app with the better star average is not the one people write more warmly about.

Rebuild Training ships an update fortnightly, Functional Bodybuilding weekly. Both last shipped on October 24, 2026.
