# X vs Ruby Pilates

The clearest difference is update cadence: X at every 3 weeks against Ruby Pilates's every 10 months. X also leads on ratings volume (440 vs 1). Ruby Pilates's advantage is monetization model (free vs ad-supported). 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 — 5.0 for X against 5.0 for Ruby Pilates. That said, the two scores are not equally well evidenced: X has 440 ratings behind it against 1, so its average is the more settled of the two.

X ships an update every 3 weeks, Ruby Pilates every 10 months. The most recent releases landed on October 11, 2026 and October 9, 2026 respectively.
