Cubeventory is a helpful Dungeons and Dragons 5th Edition tool to help track players inventory and encumberance without all the math that comes with it. The idea comes from Zee Bashew and his video on the topic (embeded below).
Each square is equal to 1 lb. Add items with the searchable combobox. Items will appear in the area on the bottom. They can be dragged with the mouse. Right-clicking an item gives options to rotate, flip, clone, or delete and these controls are avalible in the header. Your inventory will be saved when leaving the page, but can also be saved manually with the button in the sidebar. You can also save your inventory to a file to be used on a different device.
If you try to spawn an item not found in the list, you can create an item (from the result in the searchable combobox or the button in the sidebar.)
Welcome to Cubeventory on mobile! Drag items around with one finger and move the grid around with two fingers.
