# OLED Clock vs Digital Clock

The clearest difference is rating: Digital Clock at 4.6 against OLED Clock's 3.9. Digital Clock also leads on ratings volume (377 vs 15). OLED Clock's advantage is in-app purchases (none vs 12) and ads (none vs shown). On price and update cadence there is nothing between them.

Both are free to download. Digital Clock sells 6 one-off in-app purchases. OLED Clock asks for nothing beyond the download.

Digital Clock holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Digital Clock has 377 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 64% of Digital 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, Digital Clock every 2 months. The most recent releases landed on September 29, 2026 and October 2, 2026 respectively.
