Beta Testers wanted for my 3D GPS track visualizer

I'm working on a Strava like web app and I'm looking for Beta testers: https://cubetrek.com/

It's a hobby project of mine, because I wanted to build an app to track my hiking and skiing activities in a way I like it, including 3D visualization (I live in Switzerland, so it's usually always either up or down and that's hard to visualize on a 2D map) and easy comparison of past efforts on the same track.

You're more than welcome to try it out! Any feedback is welcome.
