Copic Colour DB is an Android app for managing an inventory of markers using the Copic colour code system.
To add a colour to your inventory, simply tap the square labeled with the appropriate colour code. To remove it, simply tap it again. To mark a colour as needing a refill, long press its square, and check "Needs Refill" in the dialogue.
Use the navigation drawer to either view all colours, only colours that you currently have in stock, or those that need refills.
