# Rhythm vs Fast

The clearest difference is in-app purchases: Rhythm at none against Fast's 8. Rhythm also leads on review sentiment (89% vs 75%). Fast's advantage is update cadence (every 2 months vs every 13 months) and ratings volume (3.3K vs 454). On price, rating, ads and device support there is nothing between them.

Both are free to download. Fast sells 8 in-app purchases, starting at $4.99 per month. Rhythm asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for Rhythm against 4.7 for Fast. That said, the two scores are not equally well evidenced: Fast has 3.3K ratings behind it against 454, so its average is the more settled of the two. Written reviews are what separate them: 89% of Rhythm's written reviews are positive against 75% of Fast's.

Rhythm ships an update every 13 months, Fast every 2 months. The most recent releases landed on October 8, 2026 and October 16, 2026 respectively.
