# Performance Timer vs Fullscreen Clock

The clearest difference is in-app purchases: Performance Timer at none against Fullscreen Clock's 1. Performance Timer also leads on ads (none vs shown) and iOS requirement (8.0 vs 15.0). Fullscreen Clock's advantage is ratings volume (2.2K vs 59) and rating (4.7 vs 4.5). On price, review sentiment and device support there is nothing between them.

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

Fullscreen Clock holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Fullscreen Clock has 2.2K ratings behind it against 59, so its average is the more settled of the two. Written reviews complicate that: 83% of Performance Timer'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.
