After latest update...

Haven't seen an update in quite some time, are there plans for any to be released??

Tried performing a search for email and the program crashed, now I can't get the app to run at all. Since I'm tired of being forced to uninstall the app and reinstall, and spend hours setting presences and accounts back up, I've temporarily abandoned Nine hoping an update would get the program working again while preserving my settings.

I prefer Nine to any of the other options, but these quirks are VERY frustrating!

Replaces Symantec Work Mail (Touchdown)

This app is great for those who need to use their phone for work and manage productivity in a meaningful way. Functions much like Outlook with email, contacts, and calendar. It does not currently sync with tasks or notes. Allows the user to sync multiple folders which is critical for those of us who use rules to file emails automatically. You can see your inbox and sub folders all in one place with the All Emails view. Tech support has been very responsive to making fixes. I have put in two requests and both have been addressed/responded to within 24 - 48 hours.

Battery drain

Update after losing my profile for the 4th time I can no longer recommend this app. I have a lot of folders to sync and having to reset them one by one every time Nine decides to remove my profile has become very time consuming!

Update! nine works great after iOS upgrade 11.3.1 Since update and paying the one time fee. Now my iPhone 7 battery drains down in half the time. I un install 9 iPhone battery works as expected. Re install 9 and the battery drains down very quickly. 9 worked great while I used the free version. What happened. I will give 9 5 stars when the battery drain is resolved.
Other wise this app works great the only email app that has a true unread folder that shows all unread email no matter what folder it has been moved to by rules!

Developer Response ,

Today Nine for iOS v.1.3.1 is officially approved to become available on the App Store. In this version, the important feature in the aspect of UX is included to the Calendar app so that you can change an existed events to other time bands using drag and drop. Besides of this, interesting sounds for notifications for alerts and head-ups are added. Now Nine for iOS is continuing to develop new features to rival anything you can see in the Android version of Nine. For all users for Nine, let's update your Nine with this version.
