Overview
Rollplay lets you build your own mobile character sheet for whatever you're running. Drag & drop to create a layout, setup your own attributes and dice formulas, create items and conditions that actually update stats when your players use them. No code. Share the game and your table plays it on their phones.
If you just wanna play one of the existing games, you can try some of the character sheets already in the app.

Nimble https://groupfinder.eu/library/nimble and others await you to create characters, homebrew weapons or share your creations.
Rollplay is built around automation, so homebrewing something ambitious doesn't mean a spreadsheet full of manual math. Design a race, class, item, or a whole new system: set the rules once and let the app run them. Share it with your table, and your players don't have to learn your system to enjoy it; they just play, while your rules quietly do the work behind the scenes. It's the easiest way to make your homebrew feel as polished as anything official.
For Players
Auto-Calculated Attributes
Stats update automatically as you level up, equip gear, or gain new abilities.
Automated Effects
Items, classes, and conditions modify your stats on their own, and unwind cleanly when removed, even through deeply nested chains.
Equipment & Inventory
Equip and manage items in one place, with carry weight and currency tracked for you.
3D Dice Roller
Roll skill checks and weapon hits with a single tap, with explosive dice, rerolls, and advanced roll mechanics.
For Creators
No-Code System Creation
Build a complete custom game system: attributes, formulas, effects, dice, and content, no programming needed.
Custom Rules
Define your own attributes, dice pools, and formulas. Rename core concepts like Race or Ancestry to match your setting.
Drag & Drop Sheet Builder
Design your character sheet layout visually with modular building blocks.
Share & Iterate
Push your system to your players directly, with draft and published versions so you can update it without breaking their games.
