My feeling is that there is just a bit too much motion happening at once. I think the issue is that as you scroll (I’m on an iPhone) your eye is drawn to the content that has just scrolled into view but the content below then starts to animate too early, so you’re distracted by the motion happening below the content that you’re trying to read.
This happens multiple times (for each content block…)
I think you probably just need to delay the start of the next animation until you’ve scrolled down a bit further, and perhaps even reduce the amount of movement? It doesn’t need much motion to still give that dynamic feel.
It’s so close to being quite an awesome landing page otherwise!
Edit: also while we’re all here playing backseat designer…. The first animation of the iPhone showing some sort of archiving sequence seems to run too early for me - I don’t really understand what it’s demonstrating. By the time I’ve scrolled the iPhone into view, the archive overlay has already popped out and I didn’t get chance to see what the screen before that was showing. So it’s slightly confusing (though it looks nice!)
