New app lets you "Scribble" on the HTC One (M8)3
Scribble will even allow you to create a "to-do list," although whether or not you really get around to doing all of those projects is your responsibility. The app will work with a stylus pen made for a capacitive screen. Or, you can use your finger to write and draw with.
HTC Scribble was actually available last year on the HTC One max, and is now available for free from the Google Play Store. If you like to show off your creative side, this could be a fun app to download.
