# OLED Clock vs Digital Clock

The clearest difference is rating: Digital Clock at 4.4 against OLED Clock's 3.9. Digital Clock also leads on ratings volume (153 vs 15). OLED Clock's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Digital Clock sells 6 in-app purchases, starting at $1.99 per month. OLED Clock asks for nothing beyond the download.

Digital Clock holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Digital Clock has 153 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 65% 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 6 weeks. The most recent releases landed on September 20, 2026 and September 22, 2026 respectively.
