I don't mean to be abrasive, but landing page could not be less informative. I'm a full-time developer and a big believer in code review, but I have no interest in downloading the app based on the website -- I don't know what it is, really. I think you are going to convert a lot better by actually explaining why I should download the app, rather than just providing a link. Why is this better than current tools? Does this integrate with Github? Bitbucket?
