Verdict
The clearest difference is rating: iTuner at 4.4 against Tone Scan's 3.2. iTuner also leads on ratings volume (116 vs 6) and iOS requirement (10.0 vs 15.5). Tone Scan's advantage is review sentiment (50% vs 11%) and monetization model (free with in-app purchases vs subscription). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. iTuner sells 3 in-app purchases, starting at $0.99 per year and Tone Scan sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
iTuner holds the better App Store score, 4.4 against 3.2. That said, the two scores are not equally well evidenced: iTuner has 116 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 11% of iTuner's written reviews are positive against 50% of Tone Scan's, so the app with the better star average is not the one people write more warmly about.
iTuner ships an update every 4 months, Tone Scan every 7 months. Both last shipped on November 2, 2026.
