Verdict
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.
