  • 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.
  • Nine loosing all data

    By Cutiepie260768
    Happened twice after last two nine updates.... All mail and configuration disappears and application returns to first time install screen. When you attempt to reconfigure mail settings, the application crashes and closes. Only way is to delete and reinstall from app store. I have lots of folders to sync and it is a pain to set up all over Everytime.
  • Functionally limited

    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. Do yourself a favor and just download Outlook.
  • Delay in msgs

    By godo123
    Looks like this app works better in an android phone. I’ve experienced delay In getting messages these days in my iPhone. I like this app because you get notifications for emails with rule settings vs the mail and outlook apps.
  • NOT on par with Android version

    By Unafishet
    Started using after hearing amazing reviews from Android using co-workers about this app. Seems to be missing features and is far less reliable than the Android version. Email push seems to break randomly, no dark theme, and regularly becomes sluggish. I hope it gets better but not worth using right now.
  • Getting better all the time!

    By Leotue11
    This is hands down the best email & calendar app on Android and has the potential to do even better on ios since the native email app is just too limited for a business user. It still needs optimization and features to get to the same 5 star level it has for me on Android. My main issues are: - no exchange task management - very slow Keep those updates coming!
  • Syncing Notes

    By saurabhd99
    Hi Nine Team, Can you please add ability to sync/add notes and multiple calendar the way you have it on Android? Regards
  • Battery drain

    By DougKmcse
    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!
  • Why do I need to pay twice if I have the Android version?

    By Wg-avaldod
    Buying an app should be valid for any platform. I don’t need to purchase it again if I want to use it in my iPhone.
  • How did they mess this up?

    By DeadWolfSA
    The android version of this app is so good. When I switched to an iPhone I thought downloading this app was a no brainer. It feels like it is in early alpha. No dark theme. Notifications just don’t work. There are a lot of settings in the android version that are just missing. This app comes no where close to the greatness of the android version. If you are looking to connect to an exchange or o365 environment and are on iOS I suggest using outlook instead.
