  • I would be face down in the gutter without this app. I use it on both my work (email and calendar) and personal (calendar only) phones via the exchange server at work. Only part I am not crazy about is the calendar widget which I live on from my personal phone. The widget only let's you see two weeks at a time and only let's you create a new appointment, that is fine if you are trying to set something up that isn't a month out. Instead you have to launch the app, find the calendar icon and search from there. The function is more of a hassle than anything else, it would be nice to open the app and be able to have the calendar be the default view instead of an empty work email inbox. In an attempt to keep a work life balance I can't have the emails sync.

  • Nine is a great email app. It has flawless support for Office365 / Exchange \n' + 'accounts - email, calendar, and contacts. It also works well at combining \n' + 'that with IMAP and Google accounts. Clean UI, Nice customization for each \n' + 'account, and it is easy to use. Previously, this app was fairly battery \n' + 'hungry, but recent releases have improved significantly in that area. I \n' + 'highly recommend Nine.

  • Awesome for business. Support is awesome and responsive. Let e know once IMAP is supported please. EDIT: this app is so good that I have actually leave their name in my email signature. EDIT 2: Hey 9, Chrome OS and Chromebooks are getting more and more popular. You know that android apps will be possible to have on Chromebook soon. Do you intend create app for Chromebook? This would be huge guys. Just huge! I would buy it immediately.

  • Hi 9Folders, I have a quick question and i didnt see it in your FAQ area. Is there a way to enable being able to see notes on tasks instead of just making new ones? Should probably state that i love the app as well and with the new 3.0 features i can now finally replace my task system and move everything to Nine however having the feature above would help a ton

  • This is a top tier email client, and I've used the lot on Android - trying to find a serious way to tame a work Exchange inbox. The only other client I've found that was close is TouchDown, and it's been sadly neglected for a long time. No such problem here - the devs seem right on the ball. Highly recommended.

  • Great UI! I love the integration with existing calendars. I like the option to apply the security settings at application level. It is all that I've been looking for in an office client. EDIT: their customer support is quick to respond as well. It continues to be a 5-star high quality app.
