I think that link is referring to going for a workout with just the monitor itself to record your heart rate - no other devices present. You can use/build your own mobile or desktop apps without needing their software if that's what you're wondering.

I think you should read 10% Happier by Dan Harris. He's a news anchor that tried meditation after having a panic attack on air. He's doesn't oversell the benefits (he says he feels about 10% happier) and he covers his journey from skeptic to practicing every day

freeCodeCamp is surprisingly good and teaches you a lot about modern web development
