Where to find a list of all apps

Hi all, relative new to this platform. I found lots of articles hinting to the fact that there are over 600 apps (and various analysis initiatives) using the open data of TfL in one way or another. Is there a central place where these apps and initiatives can be found? I would like to understand what kind of initiatives and unique services are created on top of this treasure trove of data.

Thanks in advance for any hint.
