# Clock mini vs OLED Clock

The clearest difference is rating: Clock mini at 5.0 against OLED Clock's 3.9. OLED Clock's advantage is in-app purchases (none vs 18) and review sentiment (79% vs 49%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Clock mini sells 18 in-app purchases, starting at $1.49 per month. OLED Clock asks for nothing beyond the download.

Clock mini holds the better App Store score, 5.0 against 3.9. Both are backed by a comparable volume of ratings — 4 and 15 respectively. Written reviews complicate that: 49% of Clock mini's written reviews are positive against 79% of OLED Clock's, so the app with the better star average is not the one people write more warmly about.

Clock mini ships an update every 5 weeks, OLED Clock every 4 weeks. The most recent releases landed on September 17, 2026 and September 20, 2026 respectively.
