Social media links should be at the bottom of the page. They are a type of call-to-action and having folks click on them is a type of conversion. Ask them to make that decision after figuring out what your app is about.
I like the layout of the product shot on the left, but the scaling is all wrong. It looks blurry.
Your tagline should give people a general idea of what your app does.
Clicking a link to a blog article should not be the main conversion on this page. I also shouldn't have to read the blog article to understand what your app does. Instead, this page should have already taught me as much as I need to know about your app to determine whether I want to keep updated on it's progress. If I do, you should be taking my email address at this point.
After reading all the copy on the page, I still don't have any idea what the app does.
I hope that helps. :)
