Stupid question: what is JOIN?

JOIN cycling app

Hi everybody, feels kinda weird to ask this on the Trainerroad forum, but I’m really curious. Laurens ten Dam has this new podcast about training, which is sponsored by (or you might say its just one big ad for) JOIN. I never heard of this app before but it claims to use machine learning to provide cyclists with personalized training. Seeing as how Trainerroad is working on this too, and is obviously relying on their big dataset, I was wondering if anybody here has used JOIN and how it compares…
