# Clock vs Fullscreen Clock

The clearest difference is in-app purchases: Clock at none against Fullscreen Clock's 1. Clock also leads on ads (none vs shown) and review sentiment (84% vs 76%). Fullscreen Clock's advantage is update cadence (every 9 days vs every 12 months) and rating (4.7 vs 4.4). On price and device support there is nothing between them.

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

Fullscreen Clock holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Fullscreen Clock has 2.2K ratings behind it against 152, so its average is the more settled of the two. Written reviews complicate that: 84% of Clock's written reviews are positive against 76% of Fullscreen Clock's, so the app with the better star average is not the one people write more warmly about.

Clock ships an update every 12 months, Fullscreen Clock every 9 days. The most recent releases landed on October 13, 2026 and October 15, 2026 respectively.
