The goal of this app is to improve your life, as a DnD Dungeon Master, or any RPG DM or GM for that matter. Currently still in alpha, but there are several working aspects as of now:
-Plot Hook Generator - Browse through hundreds of plot hooks to help keep your story interesting. You can even submit your own!
-NPC Generator - Randomly generate a very detailed NPC on the fly; your players will believe that this NPC has a purpose and is significant instead of a throwaway one-off forgettable character.
-Name Generator - With a growing list of races.
-Loot Generator - Configurable to a large variety of encounter types
-Unique Items, Riddles, Puzzles, Dungeons, and Battle Maps submitted and voted on by users.
-A convenient dice roller
-More than 120 "d100" lists - Have you ever needed to come up with a tavern name quickly? How about an interesting potion? Or the contents of a traveler's backpack? These lists contain 100+ different entries to quickly help you fill in the details of your world.
This app is open source: https://github.com/svenjoypro/RPGCompanion
and I would love any and all contributions. If you have little programming experience, but are still creative then the JSON files found here: https://github.com/svenjoypro/RPGCompanion/tree/master/app/src/main/res/raw might be more your style.
