I'm Jordan and I recently launched Untitled UI.
I've made a free version for anyone to download. I've had some really positive feedback so far, so hopefully it's helpful for you too!

We're using the full version of Untitled to build out version 2 of Himalayas and I can vouch that it has sped up our design process significantly!
Disclaimer: Jordan is a co-founder of Himalayas so my opinion might be a little bias :)
