## What is Zero?

ZERØ’s email client has been engineered to help lawyers work less and bill more. With ZERØ, lawyers can:

·         Predictively file messages to their document management system or to their corresponding email folders.
·         Sort their inboxes by parameters such as importance and sender.
·         Receive a warning in real-time if they are about to send a message to a potential wrong recipient.
·         Automatically and contemporaneously capture the time spent interacting with client messages from their mobile devices.

### 5/5 — Designed for attorneys and professionals with Document Management Systems

*2019-03-20*

This email application is designed for attorneys and professionals who are familiar with and use Document Management Systems and Time Entry Systems, and is an easy to use (and highly sophisticated) AI-powered email application. The Zero email application is not engineered for the average consumer who has a Gmail or iCloud email account.

### 1/5 — Better when it was for non attorneys

*2018-12-13*

This was by far the best email app I’ve ever used until it was completely unusable one day.  I found out why... it switched its platform over to only be used for attorneys.  Now I use regular gmail.  I’m extremely disappointed.

### 1/5 — Requires an account before using with no way of signing up

*2018-10-24*

Unusable

### 1/5 — Nothing

*2017-10-09*
