# Muse Fit vs I

Muse Fit and I both sit at 5.0 stars, but that hides the real split: 100% of I's written reviews are positive against 35% of Muse Fit's. I also leads on iOS requirement (12.0 vs 15.0). Muse Fit's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (5 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 — 5.0 for Muse Fit against 5.0 for I. That said, the two scores are not equally well evidenced: Muse Fit has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 35% of Muse Fit's written reviews are positive against 100% of I's.

Muse Fit ships an update every 2 weeks, I every 2 months. The most recent releases landed on September 11, 2026 and September 8, 2026 respectively.
