Never lose another file. Catalog your email attachments for fast and easy access to the files you need in a hurry.

Works with Gmail, Apple, MS Outlook and other IMAP based email providers. The email list is straightforward without any gimmicky features. A throwback to more simpler times, see each message as it comes in and swipe left or right to mark read/unread, flag or delete messages.

Getting to documents, photos and links is fast and easy in the visual library. Whether you’re looking for an important PDF, a link to an interesting article or a funny YouTube video, you can count on seeing it quickly with large thumbnails in the library.

You can even create your own boards - we call them cubes - to save important documents, photos and links for easy access when you’re on the go.

With select push notifications, you’ll never miss an important attachment or link while cutting through the clutter of all your incoming emails.

Give it a try today, we would love to hear your thoughts and suggestions!

Can't select & delete multiple messages at once.


Would be nice to be able to select multiple messages and delete all of them at once.

App Keeps Crashing

Bobby Vendini

Keeps crashing. Looks nice, but doesn't work.

Update: unprofessional ::: Redesign is smooth / intuitive, but sketchy privacy


Update down two stars.

Forcing you to share the app on your Facebook or Twitter in order to change your signature from their self-promoting signature is wildly unprofessional and not cool. Instant delete of app. Had great potential. No other email client does this. Combined with sketchy privacy policy and I wouldn't touch this with a ten-foot pole.

Fantastic job on the redesign. The UI and functionality is perfect. Love the one gesture functions and even read/unread from list view. After much searching, and buying/using every email app in the store, this would take the cake, but I need two things. 1) Passcode entry option. 2) The privacy policy. It implies in vague terms that they keep email/personal info for whatever they deem necessary, even after you delete your acct, unless you go through a written process. Say what? Just delete all my info like CloudMagic and Accompli assures they will do immediately. And they do not need to store credentials with gmail. Privacy policy is pretty loose in terms of what they can do with your info. I am not confident to hand over my top email keys to them.
