# QCY vs M

The clearest difference is rating: QCY at 2.8 against M's 2.3. QCY also leads on ratings volume (320 vs 19). M's advantage is review sentiment (38% vs 18%) and device support (4 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

QCY holds the better App Store score, 2.8 against 2.3. That said, the two scores are not equally well evidenced: QCY has 320 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 18% of QCY's written reviews are positive against 38% of M's, so the app with the better star average is not the one people write more warmly about.

QCY ships an update fortnightly, M every 2 weeks. The most recent releases landed on October 17, 2026 and October 12, 2026 respectively.
