    Providing a desktop-like experience, K-9 Mail supports most e-mail types

    • Clean and intuitive UI
    • Advanced e-mail settings
    • Issues with push notifications

    "A desktop-like e-mail client"


    K-9 Mail, from K-9 Dog Walkers, is an open-source application that allows you to sync your favorite e-mail right to the app. Supporting IMAP, POP3, and even Exchange 2003/2007, K-9 Mail provides tablet or mobile users with a desktop-like experience, allowing you to organize all of your accounts in one place, folder syncing, flagging, signatures, and more. If you happen to be an independent developer, K-9 Dog Walkers also allow you to join the app project in order to improve functionality.


    K-9 Mail offers a clean and intuitive interface that makes e-mail syncing a breeze. This app also provides advanced settings not found in other top e-mail apps like Gmail. Developers also respond fairly quickly with any issue you’re having with this app.


    K-9 Mail is not without its faults; if you’ve read an incoming mail through another app, K-9 Mail marks it as read. Also, this app may not provide instant push notifications when a new e-mail has been received.

    I just wanted to warn users that I spent an entire flight writing emails, saving in draft, and then when I landed and reconnected the app crashed and I lost them all.

    Fast and simple. No bloatware bells and whistles, it just does its job.
