If you're constantly battling to keep your email account(s) at inbox zero but find Mailbox a bit too feature-heavy, Triage for iOS could be worth a look. Think of the app as an even more simplified version of Dropbox's recent acquisition. Both share the same overarching mission: they aim to help users speed clean an overloaded inbox. But whereas a large part of Mailbox's allure is its "snooze" functionality — which temporarily removes selected messages from your inbox only to bring them back at a specified time — Triage's "first aid" approach to email presents you with just two choices: archive or keep. Emails are displayed in a card-style view in the middle of the screen. You can't see the entire body of a message (that requires a tap), but Triage displays enough to provide the gist of an email's importance.

It's not going to replace your primary email client

Flicking a card up will archive it, whereas throwing it to the bottom of your iPhone's screen will keep it in your inbox. Kept messages are marked as unread so you won't forget about them later, but you won't be seeing them again within Triage. Once you've made a decision on a card, that's it. The up-flick can also be toggled between designating an email as read or deleting it altogether.

We don't expect Triage to be for everyone; some users may find it takes simplification to the extreme. You won't find signatures or a unified inbox experience here. There's no support for labels or folders, nor does the app provide push notifications. To be fair, the app's developers clearly state Triage isn't meant to replace your desktop email client. And importantly, it offers more flexibility than Mailbox, with support for Gmail, Yahoo, iCloud, and most IMAP email accounts. But unlike Mailbox, this app isn't free. Triage is available as a $1.99 download from the App Store now.
