# Rhythm vs HeyFast

The clearest difference is in-app purchases: Rhythm at none against HeyFast's 3. Rhythm also leads on ratings volume (458 vs 27). HeyFast's advantage is update cadence (every 2 weeks vs every 13 months) and review sentiment (100% vs 89%). On price, rating, ads and device support there is nothing between them.

Both are free to download. HeyFast sells 3 in-app purchases, starting at $1.99 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 4.8 for HeyFast. That said, the two scores are not equally well evidenced: Rhythm has 458 ratings behind it against 27, 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 100% of HeyFast's.
