Catchbook

Works surprisingly well and is pretty intuitive. The drag/snap functions are really smooth and accurate. I drew up a couple of quick concept ideas and they turned out like I wanted without too much extra adjusting. I would like to see support for Ctrl-C/Ctrl-V instead of having to use mouse-clicks but the software is pretty young so I expect the functionality will improve. This is a great effort by Siemens and I hope it is well received. I do a lot of drawings to show concepts/ideas and there isn't a great product that does quick and nice at the same time until now. I hope that Catchbook will be able to replace PowerPoint because it is so much faster. It fills a really good need for using the tablet to do quality drawings.

Best drawing app on the windows store period. Only thing I would improve is when I export my drawings that the lines would be as clean as in the program. Other than that best program ever!

This app is great for drawing things and visualizing your ideas. It is sort of frustrating when you try to delete something because it has no eraser tool. Instead, you scribble whatever you want to erase. Another problem is that it has no ruler tool. It would be really helpful if it had some sort of ruler to guide your lines.

Great tool that takes what would be napkin sketches and automatically changes your "sketches" into lines, arcs and spines that can be used directly in your design systems (CAD).

This is really a very simple but powerful tool. Very useful for making accurate sketches. I use it to make simple design of experiments for myself and communicating with my group. Possible improvements: 1. Switchable grid lines, 2. Layers.

Looked great until it dumped an hour and a half of work. Autosave? Apparently not.
