# QdFitPro vs Clap Detector

The clearest difference is in-app purchases: QdFitPro at none against Clap Detector's 2. QdFitPro also leads on ads (none vs shown) and review sentiment (22% vs 11%). Clap Detector's advantage is rating (4.0 vs 3.8) and ratings volume (235 vs 28). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Clap Detector sells 2 in-app purchases, starting at $2.99 per 7 days. QdFitPro asks for nothing beyond the download.

Clap Detector holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: Clap Detector has 235 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 22% of QdFitPro's written reviews are positive against 11% of Clap Detector's, so the app with the better star average is not the one people write more warmly about.

QdFitPro ships an update monthly, Clap Detector fortnightly. The most recent releases landed on September 16, 2026 and September 8, 2026 respectively.
