Verdict

The call

The clearest difference is review sentiment: Tone generator at 67% against Clear Waves's 0%. Tone generator also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (155 vs 17). Clear Waves's advantage is ads (none vs shown) and update cadence (every 2 days vs every 5 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Clear Waves holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Tone generator has 155 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 67% of Tone generator's written reviews are positive against 0% of Clear Waves's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Tone generator ships an update every 5 months, Clear Waves every 2 days. The most recent releases landed on October 30, 2026 and October 22, 2026 respectively.
