After taking a 5 second look:

My guess is that the calendar invite includes a link to the site. I've known people who will block out periods of time for "Deep Work" sessions on their calendar. Could just be a convenient way of helping people schedule those and drive them back to the app. You def. don't need to use this feature.

you are exactly right: scheduling a calendar invite just reminds you not to forget to play Endel during your scheduled deep work session

But that doesn't explain why you can't just start a session.

[stvtsk]

why can't you just start a session? Click "Play" and Endel will start playing

lol, totally didn't realize either that the play button wasn't just there for show.
