TableSync
One free app for fifth edition tabletop games, in five spaces you switch between with the logos at the top: Player (character sheets, dice and spells), DM (party, initiative, encounters and session prep), Solo (adventures to play alone, or write), Map (a battle map on the table at a true one-inch grid) and Codex (every SRD rule, spell, monster and item). It works offline in this browser and on Android, with no account, no ads and no tracking.
