# Moo FM vs Zenith

The clearest difference is rating: Zenith at 5.0 against Moo FM's 4.4. Zenith also leads on review sentiment (100% vs 67%) and update cadence (every 4 days vs every 4 weeks). Moo FM's advantage is ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Moo FM sells 1 one-off in-app purchase and Zenith sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Zenith holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Moo FM has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 67% of Moo FM's written reviews are positive against 100% of Zenith's.

Moo FM ships an update every 4 weeks, Zenith every 4 days. The most recent releases landed on October 21, 2026 and October 19, 2026 respectively.
