Definitely worth it considering the added value to the project and the fact that it's free and still looked-after. Saves us a lot of time by running scheduled tests and reporting findings.
New version has some issues I hope to see solved in the next update.

This application allows to make some test in mobile or reactive applications?

Originally I rated this a 2/5 because there was little documentation and it was a bit confusing to know what the configuration items were for and how to get going.  I changed my rating to 5 because the Indigo team immediately reached out and offered to help me get it setup.  Once everything was configured properly the tool worked and worked well.  A great product with even better support!
