# Pepp vs Mellowsound

The clearest difference is review sentiment: Mellowsound at 60% against Pepp's 29%. Mellowsound also leads on update cadence (every 4 weeks vs every 6 months) and ratings volume (237 vs 5). Pepp's advantage is rating (4.6 vs 4.3) and iOS requirement (7.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Pepp sells 1 one-off in-app purchase and Mellowsound sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Pepp holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Mellowsound has 237 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 29% of Pepp's written reviews are positive against 60% of Mellowsound's, so the app with the better star average is not the one people write more warmly about.

Pepp ships an update every 6 months, Mellowsound every 4 weeks. The most recent releases landed on November 1, 2026 and November 4, 2026 respectively.
