Inbox by Gmail

ANDROID 4.1+

Leave it to the algorithm kings at Google to take a crack at antiquated inboxes with the sensibly named Inbox – an email app with a difference. It has built-in snooze and reminders, a powerful search function, and it’ll even bundle similar messages together, not just in chains but by category so you can clear your inbox with efficiency.

Throw in a nice highlights feature that shows vital info without opening the email, and this is an app with lots of nice surprises. Definitely worth the upgrade for Gmail users. FREE, INBOX.GOOGLE.COM
