Like the Peb-L-Sketch watchface the Peb-L-Sketch App is inspired by an Etch-a-Sketch however the app allows you to actually draw on the screen!
Download here at MyPebbleFaces.
Use the Up and Down arrows to draw on the screen. To change to Right and Left press the middle select button to swap the orientation (Up becomes Right, Down becomes Left).
To start over simply Back out of the app and go back in.
** Version 1.2 released April 20, 2013: Fixed bug that was causing dots to appear on the right side of the sketch area. Also some memory optimization.
** Version 1.1 released April 20, 2013: This version allows you to draw diagonally. Just press and hold the Select button and it'll switch to diagonal mode where you can draw NE/SW and NW/SE directions. To go back to normal mode just press and hold Select again. There's also a basic instructions screen on startup now that'll display for 10 seconds or until you press a button.
