I have been using the K-9 mail application on Android for some time now. I have noticed that it has made some major improvements throughout the years. I would have to say that I am most impressed with their latest release. Their interface has always been subpar when you compared it to some applications on the market. For example the Google gmail application has always been really slick and interactive interface. Now with the latest release of K-9 which I downloaded yesterday on my phone seems to be catching up. They have updated their icons to be more modern. It also seems like they have spent a lot of time improving the interface and making it more usable. It’s always been a great application for managing multiple email providers and now it has a nice interface too.I would recommend this application to anyone who needs to manage multiple emails under one client.
