NoteDex allows you to add digital 'ink' to a card - both on front and back.
You can activate Ink mode in 2 ways - by touching the card with an active stylus pen (for example if you are using a Surface, iPad or Samsung Galaxy tablet with their respective digital pens), or by clicking the ink icon with your mouse. Then you can draw on the card and use all the extensive pen features.
To get back to Text mode from Ink Mode make sure to click the Ink icon that is in blue.
