Verdict
The clearest difference is rating: QFit at 3.3 against RDFit's 2.8. QFit also leads on iOS requirement (9.0 vs 13.0). RDFit's advantage is in-app purchases (none vs 3) and ratings volume (3.1K vs 49). On price, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. QFit sells 3 one-off in-app purchases. RDFit asks for nothing beyond the download.
QFit holds the better App Store score, 3.3 against 2.8. That said, the two scores are not equally well evidenced: RDFit has 3.1K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 45% of RDFit's written reviews are positive against 24% of QFit's, so the app with the better star average is not the one people write more warmly about.
RDFit ships an update fortnightly, QFit every 2 weeks. The most recent releases landed on October 29, 2026 and October 22, 2026 respectively.
