Roll20 for iPad and Android
From Roll20 Wiki
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.
