Of course, there is also the desktop version of FamilySearch that is available to everyone for a very reasonable cost of free! LDS members [members of the Church of Jesus Christ of Latter-Day Saints] get bonus complimentary account access to the big three commercial genealogy/family history sites: Ancestory, findmypast, and MyHeritage.
On the desktop version you can upload photos/documents, video, audio and add family stories - which then are available to your mobile apps (and attached to your FamilySearch people). Sweet.
You have to have taken the photo first outside the app and have it in your photo album or on the web somewhere (like on Google Drive). I found the upload function a bit flaky with selected upload sometimes just disappearing or getting posted to an unexpected person in your file. With some perseverance I was able to upload some test pictures and remove the unexpected ones. I expect this to resolve itself as the app gets tweaked and updated.
Can't wait to try out the FamilySearch Memories app when it becomes available for my Android device!
I have installed FamilySearch Family Tree app on my Android tablet. It is somewhat interesting as it permits me to show off my current tree .. but does not really let me update it on FamilySearch .. it has menu buttons for Stories and Audio but does not appear to let you create content here .. just view what FamilySearch has. The new FamilySearch Memories app looks more promising for creating content - with a voice recorder, add photos and documents, and create stories functions, but alas (for now) it only exists for ios7+ (apple devices) for now. Some hints about an Android version perhaps being made available for end of this year .. wouldn't that be a nice Christmas present!
