Just a basic critique, but you should have a short description of what speedcubing is and what/how your software works (in general terms). I know this is probably niche software, but if people can see your vision a bit better, they might be more likely to contribute. Your current Description is pretty sparse.
"A speedcubing timer for the 21st century" doesn't really say much, especially since we live in a world where that lingo has become background noise, thanks to aggressive advertising.
I mean, people who find your software are probably looking for it, so they're probably your target audience, but you never know what might pique somebody's interest!
And maybe somebody out there has been living under a rock, has been doing speedcubing, but has no idea that's what it's called. You never know!
