When opening Mariner Calc, the screen goes black, then crashes.
With version 1.1, you will need to delete the app from the iPhone in order to resolve the current problem.
Then to get it back onto your iPhone, connect the sync cable, select the iPhone in the sidebar in iTunes. Then go to the Applications tab on the right side of your iTunes screen and scroll down to Mariner Calc in the list and select the check box beside Mariner Calc. Click "Apply" in the lower right corner of the screen.
When iTunes syncs with the iPhone, Calc should should end up back on the iPhone. Unfortunately, you will have to re-upload your files to the iPhone. We have resolved this issue in version 1.2.
