# Rhythmushi vs U

Rhythmushi and U both sit at 3.3 stars, but that hides the real split: 64% of Rhythmushi's written reviews are positive against 18% of U's. Rhythmushi also leads on in-app purchases (none vs 3) and ratings volume (21 vs 3). U's advantage is update cadence (every 2 months vs every 141 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. U sells 3 in-app purchases, starting at $4.99 per month. Rhythmushi asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 3.3 for Rhythmushi against 3.3 for U. That said, the two scores are not equally well evidenced: Rhythmushi has 21 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 64% of Rhythmushi's written reviews are positive against 18% of U's.

Rhythmushi ships an update every 141 months, U every 2 months. The most recent releases landed on November 10, 2026 and November 11, 2026 respectively.
