Verdict

The call

ToneDetector Lite and Ka both sit at 5.0 stars, but that hides the real split: 97% of Ka's written reviews are positive against 33% of ToneDetector Lite's. Ka also leads on update cadence (weekly vs every 30 months) and ratings volume (663 vs 2). ToneDetector Lite's advantage is in-app purchases (none vs 3) and iOS requirement (14.0 vs 16.1). On price, rating, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ToneDetector Lite holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Ka has 663 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 33% of ToneDetector Lite's written reviews are positive against 97% of Ka's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ToneDetector Lite ships an update every 30 months, Ka weekly. Both last shipped on October 30, 2026.
