# OLED Clock vs Flip Clock

The clearest difference is in-app purchases: OLED Clock at none against Flip Clock's 3. OLED Clock also leads on iOS requirement (12.0 vs 17.6). Flip Clock's advantage is rating (4.3 vs 3.9) and update cadence (every 4 days vs every 4 weeks). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Flip Clock sells 3 one-off in-app purchases. OLED Clock asks for nothing beyond the download.

Flip Clock holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Flip Clock has 490 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 71% of 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, Flip Clock every 4 days. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
