# Sigma vs Dance Minder

The clearest difference is rating: Dance Minder at 4.7 against Sigma's 4.4. Sigma's advantage is ratings volume (54 vs 3) and update cadence (weekly vs every 3 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

Dance Minder holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Sigma has 54 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 87% of Sigma's written reviews are positive against 86% of Dance Minder's, so the app with the better star average is not the one people write more warmly about.

Sigma ships an update weekly, Dance Minder every 3 weeks. The most recent releases landed on October 20, 2026 and October 22, 2026 respectively.
