One of the very few Solo playing apps on the market (and available on most platforms!). PUMC is not a Virtual Tabletop and does not want to be - it offers a very different, yet focused and versatile experience. You do not need to be a Solo TTRPG player at all to utilize it well - it is perfect for planning, world building and writing stories without the gaming aspect, too. The beautiful and customizeable layout makes for a comfy integration to keep you in a flow, spinning up new stories without interruptions.
At the core, PUMC is all about giving you the tools to easily write your Solo TTRPG story. It has everything needed to play a game system solo, coming with all the rules of the curent Unfolding Machines (PUM, SUM and GUM!) to emulate a Gamemasters decisions.
The options for managing world truths&events, characters and locations make it very easy to check up on your world building, switching characters to speak as is easy and comfortable and of course you can roll dice as well.
Concerning Updates, they are fast, frequent and bring new and useful features with every iteration. JV listens to his community keenly and you can give feedback and get involved as well (on Discord). For example, users requested custom tables and a tutorial for the oracles - both have been added in record time.
