New version is good

Any chance you could make the touch area bigger for switching turns easier?

Newest version broke the timers accuracy. The tenths of a second doesn't work now

Nice application, but please add penalty time

The application works well. Both the analog and digital interfaces look fine, although they could use slightly larger displays. It's easy to change the time limits, and it's nice to have a game timer in my pocket all the time. However, I really hope that the developer adds an option to have the timers continue to run after time has expired. In chess it doesn't matter, but scored games, like Scrabble have point penalties for every minute over, not an automatic loss. That feature would make the clock usable in a greater variety of games, and it seems like it would be simple to implement. Otherwise, nice app at a nice price.

I had been using the digital timer almost exclusively, but the analog timer DOES have the feature I sought. I'd still like it implemented for the digital timer, but Scrabble (and other games) players can use this timer and keep track of penalty time.

It just boggles the mind

I fail to understand why the concept of a simple chess clock is so hard for any develop to implement competently. Seriously. It's. A. Timer.

And yet, of about the three features that this one does, it fails spectacularly in one of them: setting a custom time. If you try to change the time using the standard iPhone number dials and click save... nope. Doesn't work. There's no way to change the time using the dials (for anyone interested, I actually did end up trying to press cancel to see if the labels on the buttons were reverse but that didn't work either).

It really makes you wonder if some of these developers have opened their app a single time.
