Everyone is trying to reinvent email ever since its existence. Along the way a countless number of services have been able to add new features to email and make the experience itself more pleasant to use.
The app has a beautifully simple design which tries to limit what buttons you see so you use gestures instead. With these gestures you can archive, delete and put them away into folders.
One feature which they are prominently showing off is "snooze". This enables you to take an email in your inbox and be notified about it at a later date. And yes, it does support push notifications.
The app will be available in the New Year for iPhone. You can go over to their site and sign up to be notified when it's released.
