Hi John, the app is not intended to be a replacement for the VTT but a companion to it. Check out the wiki for more information: Roll20 wiki says: Roll20 for iPad and Roll20 for Android are free-to-use mobile tablet applications focused on player-specific portions of Roll20. The simplest summary of what these applications are aimed to do would be "things you hold in your hand" at an in-person gaming table. That includes: digital dice, character sheets, handouts, and rules (compendium). To tie these features together, there is also access to Roll20's text chat features. Not included in the applications are tokens, maps, voice chat, video chat, and other tabletop functionality. Roll20 for iPad and Roll20 for Android are usable both at a physical table and with the Roll20 virtual tabletop. If you are wanting to run the VTT on a tablet I'd recommend using an internet browser like normal (remember that only chrome and firefox are supported at this time).
