Grapholite is an all-in-one diagrams designer aimed to create all types of business graphics and technical drawings from simple drafts and sketches to complex professional looking documents. Despite the fact that app was designed with low-end tablet devices in mind it contains all features that can be expected from the mature state-of-the-art diagramming solutions like Visio: a rich set of built-in themes and styles, sophisticated connection auto-routing algorithms, dynamic snap grid and integrated spline editor. The unique “sketch” mode allows single-click styling of any figure as if it is sketched by hand. You can create basic shapes and connections very quickly thanks to the freehand drawing recognition. For complex drawings, there are hundreds of ready-to-use stencils on the toolbox that can be easily dragged to the canvas.

You have to pay to group items. :(

No obvious way to print or share the work you do. Tools are relatively simple to use and fairly effective for simple drawings.

I cannot select some items in the drawing. I draw a line, and then cannot select it. Sometimes I can, select a line, but I cannot fathom what allows or disallows it. Also, the snap to and grid is confusing at best. It appears to be close to useful, but at this stage, I cannot do anything. Maybe its me. Also, in the tutorial, it states the zoom is always active. It isn't when drawing lines. And, since there is no grid scale on the screen, you have to guess distances until something is drawn. As I cannot edit (select items) I can't draw reference lines. Also it crashes quite a bit and once killed the OS.

this program creates very poor quality work without purchasing all the possible add ons and even then it is only fair. Pick points are rarely generated at the location of the object being modified making it very difficult to do any real edit other than coordinate based. The final failure is the constant crashing of the main screen causing me to restart the program.

Its a great app for basic drawing, some features are needed, and a way to work without internet would be the best thing now

Overall, a very nice app. Only problems are that it sometimes lags a lot and I have to close the whole app and restart it. Also, it sometimes randomly shuts down, so I am forced to save my work after everything I do.

Was kinda tough figuring out scaling but once I did it works very well. Not very friendly with windows 8 though. Likes to jump between my app homepage and the app itself.

Probably the best beta app I have ever used. Easy to learn, to use very intuitive. All the things I want a cad program to do. thank you for providing this.
