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!

Ratings and Reviews

Definitely not for Gmail, but...


I like this app too much &, contrary to my initial review, it's cooperating nicely with GMail. It's so simple and straightforward, and that's how email should be. No convoluted workflow processing, there's enough apps for that but few offering what this one does: a good interface, sufficient features and functions to receive, response, and process email. Now, if only the gang would keep the tool growing and not obligate us to use Cubes. I just don't get it, why do developers do this!

...maybe for Outlook 365? I'm testing this, against the multitude of other emails to enhance my productivity tools suite. Completely out of synch with Gmail but am giving it a try per others' comments for other services. I like the UI simplicity; as a minimalist and clutter/noise freak, this is key for me. Keep it sensible, efficient, and save me time/energy. Next review will be post Outlook test phase.



Not easy to add email
Waste of time....
