This is just a suggestion to add to 'taking photos' information. For over a year I've tried to figure out why I couldn't get my iPhone's camera to open when I opened the app and clicked on 'Take Photos'. I finally went to my phone's settings and the BillionGraves program. I found that I needed to allow access to my camera while using the app (apparently that doesn't automatically happen when you download the app?). I clicked on the button to allow camera access and ta-da now I can take photos at the cemetery. Such a simple thing that I had no idea needed to be done.
