It's simple to use, no need of any kind or configuration required! Just add it in you app as an SDK & start using gaze features right away with one line code - everything is done automatically by gazebot library which makes integration super easy even if I didn't know about how these things work before hand because that part was so well documented (see documentation section).
The only thing i dislike from this tool but not enough reason why should be removed/changed from its existing version :-p Is there anything left? This has been my best discovery while working on new feature recently implemented into our application called "Eye Map" where user can see his current position within specific area mapped out earlier just like google maps does when hovering over different areas.
