Congrats on building this!<p>Initial feedback:<p>That circle is gargantuan, focusing on it takes no significant mental bandwidth. Yes, that's the point of meditation, but if you challenge people a bit, it makes it easier for them to stay focused, especially for beginners. (Or maybe it's a mobile page and I just shouldn't watch it on my desktop monitor?)<p>Like the pulse in general, but maybe a bit too fast. Absolutely hate the coloring - black is having a mood impact, and washed out grey is just meh. That's probably a personal reaction, but worth keeping in mind if you want to build on it.<p>Having a clearer indication of time left might be helpful for people beginning to meditate. (If I'd built it, I'd progressively make the focus object vanish until it's gone at the end, but, again, that might be personal preference.)
