# Pinyin Chart vs ToneDetector Lite

The clearest difference is review sentiment: Pinyin Chart at 82% against ToneDetector Lite's 33%. Pinyin Chart also leads on update cadence (every 2 months vs every 30 months). ToneDetector Lite's advantage is rating (5.0 vs 3.0) and in-app purchases (none vs 10). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Pinyin Chart sells 10 one-off in-app purchases. ToneDetector Lite asks for nothing beyond the download.

ToneDetector Lite holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 4 and 2 respectively. Written reviews complicate that: 82% of Pinyin Chart's written reviews are positive against 33% of ToneDetector Lite's, so the app with the better star average is not the one people write more warmly about.

Pinyin Chart ships an update every 2 months, ToneDetector Lite every 30 months. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
