This is the way to turn your tablet into a productive diagram drawer. I tryied several apps and they were either too expensive for the service or too focused on the graphical appearance. This app gets 'to the point' resulting in a lightweigth, broadly compatible functional app. Thanks to the developer for its good job.

Brilliant! It's much easier, faster, and more fun drawing diagram shapes (and seeing them "magically" turn into precise ones) than having to pick each of them from a list. It couldn't be easier to use, as long as you take a few moments to look through the sample diagram that shows the gestures and features. (I have a feeling some negative reviewers here didn't bother doing that.) Thanks for this swell app! 😀👍

Thanks for your last updates. The app is very good, but it is missing font style as bold or italic or underlined.
