Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

iTuner ships an update every 4 months, Tone Scan every 7 months. Both last shipped on November 2, 2026.
