Crashes using iOS 7.0.2

Update: The app author responded quickly to the problem shown below when I used the in-app "Contact Us". The simple solution was to delete the app and download it again. Works great again now, even with iOS 7.0.3.

I really like the app and have used it frequently for various conversions; however, since upgrading my iPhone 5 to iOS 7.0.2, the app crashes on launch. It still works okay on my iPad 2 also running 7.0.2. Ill update the star rating if the bug gets fixed.
