Thanks! This is actually already available, and a demo of our new Gyroscope Pro offering, which is $7 a month and includes things like this new theme, custom domain name support (which is how I have it going to aprilzero.com), our healthkit iPhone app to power it, etc. Check it out at https://gyrosco.pe/
We want to build this as something that anyone can just go and sign up for and start using. I would love to get more athletes using this. We recently released a running app powered by the Gyroscope data — (see gyro.run) — and it's been really exciting to see people use it to share marathons, training, etc. We still don't have a good solution for things like gym training, which are hard to passively track, but that's something we're definitely thinking about.
