This is one of the internal tools that we built at Mobile Jazz as we always had the problem of being a remote team and therefore physically detached from our clients. Many times they had problems that we couldn't reproduce on our devices. With Bugfender we now can get access to their device's app logs and figure out what's wrong.
From being initially just a clunky internal tool, Bugfender is now a whole platform with a nice admin interface and many filtering and search options. The result is great and we're having quite some success with as not only we, but also the whole mobile developer community really loves it. And that is what makes us proud! :-)
