# Sound Generator vs Tone Gen Pro

The clearest difference is rating: Tone Gen Pro at 4.5 against Sound Generator's 2.5. Tone Gen Pro also leads on ratings volume (48 vs 2). Sound Generator's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 75%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Tone Gen Pro sells 1 one-off in-app purchase. Sound Generator asks for nothing beyond the download.

Tone Gen Pro holds the better App Store score, 4.5 against 2.5. That said, the two scores are not equally well evidenced: Tone Gen Pro has 48 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Sound Generator's written reviews are positive against 75% of Tone Gen Pro's, so the app with the better star average is not the one people write more warmly about.

Sound Generator ships an update every 5 months, Tone Gen Pro every 3 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
