Zero Inbox

Their settings had two icons and a button labeled, “Connect”, which was unresponsive. I think this app is phishy.

As a user of Inbox by Gmail I was not happy with Google discontinuing the app, and have been trying out numerous other email apps. There are many apps that offer a lot of features and integrations but have a steep learning curve. This app is dead simple and focuses on your inbox, and allows you to process your email without a lot of extra steps. The app allows me to see the tire email without showing me all the controls. The email processing controls are hidden but easy to get to with a simple swipe. If you are looking for a simple email app this is perfection.
