Delete IFD Trainer and IFD100 apps before Installing New Versions of IFD Trainer and IFD100.

An existing forum post details troubleshooting a crash that occurred after installing the new IFD Trainer app:

If you download a chart, the chart gets stored in the App Group, and then the chart is immediately available to all the related apps. The App Group also stores common settings used in the apps. The problem occurred because the format for some of these settings differ between app versions. For this reason, the App Group must be removed. Because the App Group remains until the last of the apps that reference the App Group are deleted, all apps must be deleted before installing the new versions.

Until this problem is corrected through an app update, the solution is to remove all apps and then install the new versions.
