  • So far so good.

    Used this application on android for work and loved it. Seems to work much better than the default email app and outlook. Finally I can push folders and get notifications.
  • Very promising, needs improvement

    First, Nine email is my absolute favorite email client for Android. When I saw this for iOS I was very excited. Frankly, my following complaints are most likely due to iOS but here goes. First: I experience frequent out of sync issues. Emails showing as unread and actually read on my PC. I have to manually mark them as read on the Nine email app. Second: emails are delayed or do not actually PUSH. Some days things work great, others not. I'll open the app and I'm flooded with new emails. I'll check the default iOS Mail app no issues. Granted this is a common occurrence with other iOS mail apps. Suggestions: Allow default browser and maps selection. Allow for either a separate calendar app or allow for a shortcut icon on home screen. I have high hopes for this app and the continued development. Already spent the money for lifetime subscription. Keep up the good work.
  • Push not working consistently

    I have used this app on Android for years and it has been solid. I recently got an iPhone to replace my android and this was the first app I installed. I am currently on the trial period since I could not transfer my android license over. As of right now I will NOT be purchasing this app. I am constantly not getting new emails via PUSH. I have the iOS mail client co figured as well and that works without issue. I can’t use this app with fear that I will not be notified that I received an email message unless doing a manual refresh. I have uninstalled the app and reinstalled with the same issue. Also I have had to re logon to my office 365 account a few times in the past few days. For some reason this app is not keeping the connection to my office 365 account. I am happy to keep the app on my phone until it is all fixed and then pay but unfortunately once the trial ends the app becomes useless to me and I will uninstall. I get error -5508 a lot
  • Functionally limited and buggy

    By Catbingo920
    Compared to the Android version, which I love, this version basically has no features at all in comparison. Ex: you can't set it so the app will only notify you certain days of the week. Also, email push doesn’t seem work unless I go into the app and sync my emails manually, and even then it might take a few minutes for my emails to actually show up. Do yourself a favor and just download Outlook.
  • No gmail support

    By Jerry7709
    This is the only email I’ve seen that doesn’t support gmail. I won’t buy the app until it’s supports gmail. Looks like a great email client will pay once I can add gmail.
  • After latest update...

    By That'sMyStory
    Notifications for email are working well, calendar alerts rarely work. I'm really starting to like this program, but the calendar alerts being unreliable really needs to be addressed. Also, how about showing the number of messages unread in the folder list? This is also badly needed.
  • Great app

    By Zaerion
    Latest update fixed the push issue I was seeing. Thanks!
  • Keep loosing data

    By karu_a
    Constantly getting logged out of the app. Will have to re-setup my account everytime at least once or twice a week. I loved the client on Android but the iOS version can't compare. I love the all the bells and whistles this app has but it's unusable when I realize my mail hasn't been syncing for a day or two because everything has been lost.
  • Battery drain

    By DougKmcse
    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!
  • Worth the fee

    By tjcostello6u7
    As a heavy user of email this app has it all and was from me worth the purchase. You can view your email in a multiple of ways and it syncs over multiple devices. It allows those who want to test it a 14 day free trial with all the functionality of a purchase so I knew exactly what I was getting.
