# OLED Clock vs Desktop Flip Clock

The clearest difference is rating: Desktop Flip Clock at 4.6 against OLED Clock's 3.9. Desktop Flip Clock also leads on ratings volume (191 vs 15) and iOS requirement (9.0 vs 12.0). OLED Clock's advantage is in-app purchases (none vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Desktop Flip Clock sells 1 one-off in-app purchase. OLED Clock asks for nothing beyond the download.

Desktop Flip Clock holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Desktop Flip Clock has 191 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 79% of OLED Clock's written reviews are positive against 74% of Desktop Flip Clock's, so the app with the better star average is not the one people write more warmly about.

OLED Clock ships an update every 4 weeks, Desktop Flip Clock every 3 weeks. The most recent releases landed on September 20, 2026 and September 22, 2026 respectively.
