Best diagramming app on the AppStore


One of the most feature-packed and powerful diagramming apps you could ask for on a mobile device. So much so, that they have a very detailed and thoughtful tutorial explaining the drawing gestures and many features within the app. It makes the initial experience with the app much smoother if you take the time to read it. Once you have the basics down, it's very intuitive and easy to use. Extremely impressive app you've made here developers.



I have another vector drawing app that meets my documentation needs, and I was looking for something simple that I could use to rough out a diagram quickly. I think this meets both needs, and with it I can produce my final diagrams more quickly. I haven't put it to the test of actually producing diagrams for my documentation but it is so much fun I decided to go ahead and buy the full version.

Great diagramming app I have used so far


Wow. Simply amazing app. Shape recognition works like magic. Diagramming no more feels like tedious task. Shape recognition improves Diagram creation time by great extend.

But still some glitches present, like fill operation is bit confusing. Image export doesn’t seems to be working reliably.

Overall, great app worth spending time and money. Good job team!!
