I like this app because it is very simple and only does basic graph paper. No fringes, no color, no extra’s. Just lines, dots and words. I love it for planning quilts that I’m trying to design. The only thing I would like to have is the option to print with the grid in the background on my drawing. Maybe I haven’t explored the options close enough but I can’t find the option. The app only prints the lines I drew on the paper so if I left 2 squares between lines or 3 squares between lines I never know unless I label the space. Not a huge problem to label things but it would help me in my situation to have those lines available.

Thank you for your review!Printing the grid lines is possible by using the Export-Command in the File-Menu. There, you can choose to print gridlines as well as a border for PDF and EPS.I am glad you like the basic approach. Hopefully you do not mind if the next version of the application includes colors. :)
I love this app

This is a great little app. What makes it great is what is not. It is not a photoshop, illustrator, visio, or even paint clone. It is a simple diagramming tool. It is minimalist which lets you work quickly without too much thought. I used it to design my new kitchen.I almost hesitate to suggest new features. It would be sad if this app became yet another bloated graphics app. I can see the author is very judicious in deciding what features to add. I would even hesitate to add color, because then you’re in the realm of color choosers, palettes, and other nonsense. About the only feature I’d consider requesting would be a choice of 3 line thicknesses: normal, thick, and dotted. But even that might be overkill.Thanks for making such a useful app!
Developer Response
Thank you for these words! You are right, I am restrictive with the features but feature requests are always welcome and noted. Development had been postponed for some time now but is in the process of being restarted. Colors have been an ongoing request. Line thicknesses is a new request, I would need to think about how to integrate it properly.
So far so good!

I recently downloaded this app and i love it. Its easy to use and it doesnt take a rocket scientist to use it. After i finshed my project i played with the print set up and got it perfectly how i needed it with a few clicks. Only thing i would like to be added would be click and drag to make circles or ovals the same way we can make squares and rectangles, Wouldve been the icing on the cake for my project. Other then that i like it and hope to use it for further projects.
Developer Response
Thanks! Circles and ovals have been a huge request and the next version would include that. Development had to be put on hold though for a couple of months. Stay tuned!
Very useful app!

Love using this app. You don’t have to be an engineer to use it. Simple and useful features. I use it on my wood working projects to help plan things out and develop cut lists. It turly is great for this. I especially like that you can export then print out your work in color while maintaining the graph. If I had to change anything it would add scaleable fonts and a circles or oval function.
Developer Response
Thank you for that review. Nice to see the app in practical use! About the circles: This has been a long requested feature but still needs some time to get implemented properly. The fonts have also been requested but will take longer still.
