# Muscle & Motion vs Vector

The clearest difference is ratings volume: Muscle & Motion at 681 against Vector's 5. Vector's advantage is review sentiment (100% vs 77%) and update cadence (weekly vs monthly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Muscle & Motion sells 3 in-app purchases, starting at $15.00 per month and Vector sells 3 in-app purchases, starting at $59.00 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Muscle & Motion against 5.0 for Vector. That said, the two scores are not equally well evidenced: Muscle & Motion has 681 ratings behind it against 5, so its average is the more settled of the two.
