Pretty self explanatory. Tap the eraser to enter eraser mode, then tap it again to enter pen mode. If you want to clear the screen, than hit the “Clear All” button and answer “Yes”. If you want to use a black pen, click the button that says “black pen”, and to go back to rainbow, click it again. See? Not that hard. Press the “Close Dashboard” button to open and close the tabs and stuff.
I got the idea from Rainbow Oof Painter (for the rainbow pen), but that is it. Recommended pen size is 15. Some things you can try: • Draw a double helix. • Make a new thumbnail for your profile. • Set the pen size to 100 and drag your finger slowly across the screen. • Set the pen size to 100, put one finger on the screen, another on the pen/eraser size scale, and slide the lever all the way down, making a rainbow cone-like shape.
