# Function Health vs Ruby Pilates

The clearest difference is monetization model: Ruby Pilates at free against Function Health's subscription. Function Health's advantage is update cadence (weekly vs every 10 months) and ratings volume (25K vs 1). On price, rating, 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.

On the App Store both sit at effectively the same score — 4.9 for Function Health against 5.0 for Ruby Pilates. That said, the two scores are not equally well evidenced: Function Health has 25K ratings behind it against 1, so its average is the more settled of the two.

Function Health ships an update weekly, Ruby Pilates every 10 months. The most recent releases landed on October 13, 2026 and October 9, 2026 respectively.
