On the Verbum 5.1.0 app, on a Samsung S5 mini, I tried out the new Prayers feature and was able to repeatedly crash the app doing the following:
1. Delete all your prayer lists, so all you see is "Today's Prayers - 0"
2. Tap on "Today's Prayers"
3. Tap the + button to add a new prayer
4. Tap on "Lists - Untitled Prayer List" to try to create a new prayer list. The app crashes immediately every time.
