Right, so I get into the "private beta" and go to the link in the email. It gives me a popup saying, "Please use an iPhone to install this app."
Meanwhile, on their homepage: > Access from anywhere - on mobile, email, or the web
If having an iPhone is a requirement of using your website (which I assume functions perfectly well on its own), you're doing it wrong. If the website is merely a way to view (but not edit) your content, then you're REALLY doing it wrong.
Also, why are people still developing exclusively for iPhone? Last quarter there were four times as many Android phones sold as iPhones.
