Pretty good on iPad

The actual diagram creation functionality is great. Where I ran into problems (even after buying a license) was in the export/sharing. I used a big cloud to signify, you know, “the cloud” and then put some EC2 objects in it (top layer), a connection between them with a label, and a text call out. When I went to export/share my finished diagram I discovered that only the EC2 images within the cloud were visible. No amount of fiddling would get the link, text, and call out to appear (different export options selected, for example). Eventually I deleted the cloud and just used a group boundary box, and that worked fine. Also the transparency settings didn’t overlap with the selected object underneath well and were unusable. Please fix these issues and I’ll change my rating to five stars.

Thank you for the feedback. We cant seem to replicate the layering issue you are experiencing. Could you please email us at with more details on the shapes used and the sequence of steps? Thanks again.

Good, simple flowchart and diagramming app

Updated review. This is a good, simple diagramming app for IOS. I often end up creating diagrams and flowcharts and this is one of the better apps out there for IOS. Intuitive and easy to use with fingers or a stylus. I also managed to import icons and diagrams freely available on the web. This is a good capability because apps often do not have everything you want.

Some suggestions for improvement:

1. An ability to at least EXPORT or SAVE AS Visio .VSD files.
Obviously it is better if you can read (IMPORT/OPEN) and write to .VSD
2. An ability to alter the TRANSPARENCY LEVEL of a shape.
3. An ability to add in shadowing or 3D bevels on a shape.
4. SAVE AS or EXPORT to JPEG (.JPG) should probably not be in the SHARE Menu.
5. An ability to SAVE AS or EXPORT to .PPT
6. An ability to SAVE AS or EXPORT to .PDF should probably not be in the SHARE Menu.
7. Coloring of lines needs to be easier. Right now you have to create the line, select it and change the color. It is useful to have another option to select a color and draw.

This app does, in all fairness, make drawing arrowed lines, etc between objects very easy by selecting an object, tapping on the chain icon, selecting what point you want the arrow to start from on your object or shape, and then selecting a point to connect to on one of the other shapes. It is an extremely good interface.

These is an ability to export files, but it is unexpectedly hidden in the SHARE menu, which you reach by the path MENU>SHARE>(select file export type)

SHARE is usually used as a menu choice in most apps to send information via email, post to a site, etc. I did not expect to find file export capabilities there at all. Usually that is in a SAVE AS menu, but SAVE AS in this app is only for saving a copy of the drawing under another name. There is nothing wrong with doing it this way, but the developer may want to consider just renaming this to EXPORT.

PDF, JPG, PNG, SVG and GSP are presently supported. If you needed to bring the drawing into PowerPoint or Visio, you could export them to a format and insert them as JPG, etc. so a workaround is provided, but it would still be useful to work with these files directly or have some sort of add on app that just converts files between Visio VSD formats and the native file formats used by the app.

Thank you for the feedback and suggestions.
The diagram can be exported to JPG and PDF using the share button from the pop-up menu and selecting the JPG or PDF option.
Thanks again for the feedback.

Great app but text editing inoperable

The app is fantastic. However, trying to edit the text is making me want to throw my phone out the window. I am about a day away from deleting it and starting over with another app instead. When you try to edit existing text, you can’t choose where the cursor goes. So you press in one spot and it puts it in another. It wouldn’t be a problem if you could actually get to the text you need to edit, but they don’t give you away. So if I have a block with say 100 words, I have to delete it and start over. If there was a way to communicate via the app or their website I probably wouldn’t be writing this on a review. I like how easy it is to add blocks and connect them.
