My original iOS Chess Clock from 2008 is back... in all its old-school Skeuomorphic glory! Two clocks. Tap one to start the other counting down. Tap both to stop both. Tap the little clock icon to set the time, and the info button to change the settings. Chess Clock includes features found in competition chess clocks, including Fischer, Bronstein, and USCF ("Simple") delay modes, which work in both digital and the visually appealing analog mode. Also, since this version was rewritten entirely within the borders of Switzerland, I guess this might be the cheapest Swiss timepiece you can have. Features: • Analog flag movement that swings back and forth as it falls (which took me a silly amount of time to get right, but I like it) • Set each clock independently • Analog and digital modes • Adjustable time delay (Bronstein, Fischer, and USCF modes) • Highlights the currently running clock

Verdict
The clearest difference is ads: Blitz Clock at none against ChessClock's shown. Blitz Clock also leads on update cadence (every 3 months vs every 8 months). ChessClock's advantage is iOS requirement (15.4 vs 26.0). On price, in-app purchases and device support there is nothing between them.
