I recently finalized an update to Dice Tracker for iPad, and it's on its way. The interface and interactions have changed slightly, and the visuals are now more aligned with iOS7. I added some indicators for alternate dice modes, and also included a "stack" counter for both of the stack dice modes.
Another big update is that all the features of the app will be free going forward. No more in-app purchases.
I'll post note once the update is live in the app store.
[UPDATE]: Just received app store approval, and it should be live in the App Store later tonight (February 19, 2014).
