Quick thing to fix:

When the page loads in my browser (1366x768 resolution), it automatically scrolls me down the page a bit, enough so that I cannot see the EasyCal logo without scrolling back up.

This is because of the auto-focus on the email address text field under "Interested in using Easy Cal?". Maybe remove that and only apply it when "I want to try it!" is clicked?

Kareem, I may not be the intended audience for your webapp but I couldn't figure out what the term 'booking' calendar meant. May be you could put up a few situations when someone would use your app to help understand your app better.

The blue is really strong, but other than that, I think it looks fine.
