# Tone generator vs Sound Generator

The clearest difference is rating: Tone generator at 4.0 against Sound Generator's 2.5. Tone generator also leads on ratings volume (152 vs 2). Sound Generator's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Tone generator sells 3 one-off in-app purchases. Sound Generator asks for nothing beyond the download.

Tone generator holds the better App Store score, 4.0 against 2.5. That said, the two scores are not equally well evidenced: Tone generator has 152 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Tone generator's written reviews are positive against 100% of Sound Generator's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 months. The most recent releases landed on September 17, 2026 and September 9, 2026 respectively.
