You may be aware that Ancestry.com developed a mobile app. The Ancestry app (Android, iOS; free) is essentially a bridge to your online Ancestry family trees (public, private, and those share with you). It’s a good app, and mimics the look and feel of your online tree. You can view your tree, add to it, and edit information.
