Hi I would like to suggest using HTML 5 instead of flash I think it is to display the current tree view.  I use an iPad almost exclusively to view the site and can't see the tree view.  I have downloaded the mobile app but don't like it as I can only view the tree and not make changes to it.

Im testing this product out and it does have some nice features over ancestor.com however, there is opportunity in the heritage product to make it more end user friendly such as editing people (make it easier) and adding people (when I'm reviewing a smart match make it easier to add relatives of the smart match to my tree like ancestor.com).

This program has a lot of potential - make a slick GUI interface that is easy to navigate and edit.
