Viewing Family Tree and adding digital files has recently gone mobile! Two new apps, FamilySearch Tree and FamilySearch Memories, now make it easy to connect with your ancestors wherever you are. You can swipe, pinch, and tap to view your ancestors who are in Family Tree and to add photos, stories, documents, and something new—audio files. Best of all, these apps for handheld devices are available free of charge.
