# Muscle & Motion vs CoreCoach Biofeedback Training

The clearest difference is in-app purchases: CoreCoach Biofeedback Training at none against Muscle & Motion's 4. CoreCoach Biofeedback Training also leads on review sentiment (100% vs 77%) and iOS requirement (14.0 vs 18.0). Muscle & Motion's advantage is update cadence (monthly vs every 32 months) and ratings volume (681 vs 3). On price, rating, ads and device support there is nothing between them.

Both are free to download. Muscle & Motion sells 3 in-app purchases, starting at $15.00 per month. CoreCoach Biofeedback Training asks for nothing beyond the download.

Muscle & Motion holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Muscle & Motion has 681 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 77% of Muscle & Motion's written reviews are positive against 100% of CoreCoach Biofeedback Training's, so the app with the better star average is not the one people write more warmly about.

Muscle & Motion ships an update monthly, CoreCoach Biofeedback Training every 32 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
