A Tool Prototype for Free-Form Sketching and Flexible Modeling

If you have a mobile or tablet device running Android 3.0 or newer, you can try out FlexiSketch for free! Choose one of the two options below. If you only have a PC/Mac, see the second option. You can learn more about the theory behind FlexiSketch here.

—— Early but stable prototype ——

The prototype can be found on Google Play under this link. (Alternatively, just enter "FlexiSketch" as search term on Google Play.)

If it is not available on Google Play, you can download the same version from here. On your Android device, go to the Settings, then to "security", and activate "Unknown Sources". Then, you can install the app by tapping on the downloaded file.

—— More recent, work-in-progress prototype ——

You can find the FlexiSketch version that was demonstrated at ICSE 2015 and presented at RE'15 at this link. Important: this is a work in progress prototype, use at your own risk! This version has more features and includes a collaboration mode (collaboration mode needs a PC/Mac with Java installed, in addition to Android devices). The PC/Mac version does not include all features.
