One of the best apps on the AppStore

Feature filled diagramming application. Be sure and take the time to follow the tutorial as it will make your initial experience much smoother. Once you have the basics down it’s actually quite intuitive. Great for any type of mind mapping/diagramming. The network diagramming is worth its weight in gold. I use it for planning network installations and mapping existing ones. Try the free version and get your bearings. Once you get the hang of it head back and purchase the paid version. Keep this baby alive by supporting the developers because there isn’t another one like it in the AppStore.

👍 Thanks for the pdf export!

Great even without Pencil support

Tried this out together with a bunch of other apps for drawing diagrams on iPad Pro with Pencil. This one turns out to be the most intuitive once I learned the few gestures, even though it doesn’t support Pencil.
I used to dread doing diagrams on PC/MAC, even with tools that are supposed to make it easier such as Visio. Now I do all my diagrams in this app and then export them.

This is also great for face-to-face discussions when, for example, there is a need to quickly come up with a sequence diagram or a flow chart. It’s as intuitive and fast as pen-and-paper, but with the ease of making modification on the fly.
I can honestly say that this is the app which makes me feel comfortable to just bring an iPad Pro to a technical meeting.

I’ve been using this for 6 months and I can’t praise this app enough. I just hope the developer will continue to improve it.

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.
