For free thinkers

Great App. Does exactly what you need and quickly to project plan and to 'think with ink on paper'. Good job! Thank you!

UML quick and fairly easy

I will buy the full version in gratitude for such a simple UML sketching tool.
Creating an object diagram was as simple as sketching a few rectangles, dropping in the shape for active classes from the built-in photo gallery, double-tapping each box to add text and then sketching lines between them.
By tapping the lines, I was able to add the end symbols for composition and aggregation.
Finally, I exported it as a PNG into the camera roll and sent it by email ready to be included in my documentation file.
The free version has all features and is merely limited to retaining 5 diagrams.
