Little late replying to this -I'm the developer of Crystal.
Sorry for the silence, totally not intended, but there really hasn't been much to say while I've been developing it. I've been posting a lot to twitter, but nothing major enough to blog about.
As of right now it's mostly finished, apart from the UI design. Currently I have a limited amount of testers using Crystal, and I am letting a few more people in every day. You can find out a bit more about Crystal beta in
this blog post and sign up to become a tester. The first 1000 to sign up are guaranteed to get in once TestFlight is allowed for iOS 9 applications and there is a chance to be randomly selected to join the limited beta (limited to the amount of UDID's I can register on my dev account)
I made another update last night where I benchmarked 10 common websites and show how they perform with Crystal. You can find out more
here - TL;DR: On average,
pages loaded 74% faster with Crystal and used
53% less bandwidth.
Last thing - There is a small splash page I made for Crystal,
