Yes it does look pretty cool!
Steve Neal sent an intro email connecting me to John Nichols from Velocity and it was obvious that this would be a good addition to the ecosystem. Velocity got the work done very quickly. I have been doing quite a bit of work to make integrations easier and 2-way sync seamless.
I have also been doing a lot of LinkedIn stalking, trying to get in contact with device manufacturers (Amazfit, Bryton etc.) to get Intervals.icu on their computers and watches. Not too much success so far. Also been contacting people with interesting apps badly impacted by the Strava API changes. The Intervals.icu API payloads are similar to the Strava API.
