Just a quick note: I'm not affiliated with the app or its creators in any way, but I have been a beta tester for it, and it's working pretty well (the app is bootstrapped so far). The Kickstarter is to add integration with other email providers (Exchange, etc.) and to create a web app that integrates with it.
That is correct. The iOS app will go live in October and folks are welcome to wait for that if they'd like. We're hoping to raise funds for expansion of engineering into web and android platforms via Kickstarter.
