# 摩刻健身 vs Sigma

The clearest difference is review sentiment: Sigma at 87% against 摩刻健身's 0%. Sigma also leads on update cadence (weekly vs monthly) and ratings volume (55 vs 1). 摩刻健身's advantage is rating (5.0 vs 4.5) and device support (4 vs 2). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

摩刻健身 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sigma has 55 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of 摩刻健身's written reviews are positive against 87% of Sigma's, so the app with the better star average is not the one people write more warmly about.

摩刻健身 ships an update monthly, Sigma weekly. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
