We would like to state that we have no commercial or scientific interests. All we want is to help the community to improve research and in this way help conservation of endangered species. We do this (in our spare time) simply because we enjoy it and want to contribute.
All work is done for free, but as owners of small enterprises, working on the tool also means no income whatsoever. Donations or grants for future development are most welcome.

You can use all versions of I3S free of any charge. You are allowed to modify it, copy it, and distribute it under the GNU Public License v2. Please feel free to contact the I3S team if you need adaptations of the tool for your research. Any feedback on the tool is welcome and we are happy to help you. For instructions on how to make pictures that are well enough to be used in I3S, please read the FAQ.
Version numbers are related. All major releases (of Classic, Pattern, Spot and Contour) will have the same and latest features and improvements (if applicable). Usually new features or improvements are developed upon a specific request or if certain bugs are noticed in a particular version of I3S. These are all taken into account for all versions of I3S in the next major release.
Check for more video tutorials of all applications on our I3S Channel on YouTube on a regular basis! We strongly recomment to read the manual and have a look at the instruction videos.
