TimeSync has been updated to version 1.3 and has been submitted to the App Store today. It will be available for download shortly.
In this free update, when the lap timers are disabled and only the TOD clock is displayed, you can tap the screen to freeze the TOD clock. Tap the screen again to resume displaying the current Time Of Day.

I used your application for the first time this weekend at a local TSD rally. Very nice app! Simple and uncluttered, perfect for in-car navigator use. I have two feature requests. One, can you offer the option to pause the TOD display with the timers present? As I understand it, the pause option is only available without the timers. And two, can you allow even more timers on the screen or, perhaps, log the previously captured timer(s) and display them on the screen? For instance, when I stop a timer I’m given the option to save the time as a leg and this saved time is displayed on screen. Just a thought. Thanks for building a great app! -David
