Email App Concept

A quick look at something we've been working on last week. We're still not sure whether this is something we want to build or not.

It's a simple idea. Usually our inboxes are a big mess. We receive everything from anyone. Our idea is to create an app that allows you to create folders based on your contacts. Basically we want users to organize their emails and give them a better sense of what is important.

What do you guys think? Do you like the idea?
