Sorry ;)
Yes, recording is only possible on mobile devices, because otherwise it's far too easy to reach long distances. It's very easy to bypass scrolling on a workstation! And yes, some people have scrolled for an hour and a half :P
Tbh, I tried to fake the scrolling as well :D First with the infinet scrolling wheel on my mouse, then with a short console script :D But well played with mobile only recording! You are also totally right with the comparison to instagram scrolling. Same useless thing. Thank you, your "app" is great!
Thank you so much for your feedback ;) I really appreciate it! And yes, that's the goal, to criticise endless scrolling on social media. Thank you for your kind words.
The punchlines are there mostly to make the empty scroll a bit more entertaining while you go down. But you're right that nothing really scrolls by in the traditional sense.
The idea is more about measuring how far your thumb travels than about browsing actual content.
