BillionGraves provides an app for smartphones so that users can take photos of gravestones at any cemetery worldwide and upload the photos to the BillionGraves web site. Users can then transcribe the gravestone information from the photos online. Use of the site is free. You can either earn or purchase extra features such as the "Record Watch" that will alert you when a specific search term of yours comes online. Earn some of these features through participation in the BillionGraves project by uploading and transcribing photos.
