Allow Grafio to become an extension of your fingertip. Draw a rectangle, circle or an ellipse and watch Grafio recognize and replace it with a perfectly looking shape for your diagram or schematic. Grafio has been around for 8 years already, polished, efficient and full of features achieved through more than 30 updates and free upgrades.

Drag and drop objects on the canvas for more complex diagrams. Make connections and add text and images. Everything you need for visualizing your idea.

The shapes you draw are automatically closed and straightened, all primitive shapes are instantly recognized. The lines you draw between shapes are automatically turned into connections thanks to our shape recognition algorithms.

Some diagrams require more advanced objects. Grafio provides hundreds of shapes you could easily drag in from the library. You could also insert images from your Camera Roll as shapes and connect them to your other shapes.

Recording audio notes to your shapes could be a way for you to collect your thoughts or you can use this feature for something more creative, like taking an interview or recording your riffs for example.

We developed а non-intrusive interface that will get you straight to the point. All advanced features you might need are also there hidden beneath the surface. To have all that power on your iOS Device at your fingertips is truly amazing!

Best app like this I’ve found, almost there

Does the job on the whole very well. Only annoying thing is the arrows never really work, or very sporadically, the shape recognition is about 90% consistent (pretty good and very quick to correct) and sometime when you want to move things it just doesn’t happen. That said it is quite impressive and by far the best flow chart app I’ve found.

Shape recognition doesn’t work well

I purchased this app to see if I could use it to replace TikZ and speed up my workflow using shape recognition. However, in my (admittedly rather short) experience, it simply does not. The shape recognition likes to give you very strange results if you attempt to draw things quickly and roughly. I think this would be acceptable if the results were close to what you actually drew, which strangely is often not the case - I’ve had drawings where bits get ignored or where points in a triangle get moved for seemingly no reason. This would all be acceptable, as I’m willing to put in the time to draw nicer shapes, but for some reason grid snapping just doesn’t work, at least for drawing. This is incredibly frustrating as I feel like this should be relatively simple to implement and it would save me from having to manually resize every shape I draw.

Developer Response ,

Thank you for the in-depth description of your needs. A new shape recognition engine will be provided in a future free upgrade as well as the ability to snap to grid more things than now.

Good app; well priced

Most similar apps use a subscription model or in the case of OmniGraffle a hidden subscription model where the developers bump the app version every year and force users to upgrade at great cost. This app is a pleasure to use and well worth the price.

Wish list for future versions:

1. It would be nice to be able to align and distribute objects evenly easier.

2. Be able to select an existing file when saving to DropBox. Currently you have to save to a new file every time.

3. iCloud support

4. Auto fit canvas to objects with the ability to set padding.

That said, great app and well worth the price.

Developer Response ,

Thank you for the kind words! Here is a rough overview of where we are according to your wish list:
1. Align/distribute is coming soon with Grafio 4, a special toolbar will help adjust everything down to a single pixel.
2. This will change with Grafio 4 too as it's using a standard file browser which allows you to use different cloud providers.
3. Same as above.
4. Auto fit sounds good, will put it into the feature request database for future versions.
