Terrific start in providing a comprehensive Divine Mercy reference. Two suggestions for your first update: 1) Improve navigation between pages by including next and back buttons, so that the user is not always forced to return to a main topic in order to select another sub-item; and 2) Include the entire text of the Diary and Divine Mercy Booklet as in-app purchases, instead of just giving excerpts. These are both essential works that users would be glad to pay for to have on their devices.
