need/ please help identifying trail photo program

i watched a Youtube video a few months ago. it was about a program which issues a stand for a smart phone. subscribed members of this group would put their phone into the stand (which assured all photos were taken from an identical point of view), take a photo, and upload the picture to a central, sponsoring website. the resulting string of photos would offer information how the view changed.


Q: anyone know of, or have a link to this service?

thanks
