I want to love this...

I really want to love this app. I am an avid user of Boomerang on Outlook for Mac and i really want to be able to use it on my phone. This is the second chance I’m giving it but i still can’t transition from the native mail app because of the way the emails in threads are organized. It drives me insane. If I have more than one email in a thread I can’t find the right one to reply to, forward, or boomerang and it drives me nuts. Everything shows up at once in a long confusing list. I need clear navigation between particular emails and I have tried to adjust the mailbox settings but there are none. I like everything else about this app but this major issue is a deal breaker for me. I really hope it is fixed somehow.

I really want to like this app

I’ve taken a break from Outlook to try things out with Boomerang since it’s the hot new thing right now. I’ve installed a boomerang add-on to my gmail and it works perfectly. I think it’s a cool feature on any email platform.

But the email app... meh. Great interface and nice features. It’s good to look at but I’ve struggled with basic functions like: receiving my emails in a timely fashion or getting notified when said email finally comes in. A lot of the time I’d have to go into the app to refresh before discovering that I’ve missed several messages. Believe me, I’ve toyed with all the notification settings both on the app and on my phone to make sure that everything is turned on. There are no settings to control the frequency in which the app fetches. What good is having the bells and whistles if it cannot do the basic things you need it to do.

So... Outlook and I have worked things out. It is just a more reliable app. While not as attractive as Boomerang- Outlook is a better fit for my very basic needs.

Great app with a big flaw

I have always been on the hunt for a email app to replace the default apple mail app. I have used outlook, spark, Edison, airmail...along with many others. I really did like this email app. I thought the interface is simplistic, yet elegant. The email viewer doesn’t have a lot of fluff and is reminiscent of Spark, in that regards. I do like the “Brief Me” function, which is essentially like a calendar function. Some have noted the Boomerang only syncs with limited email clients and that doesn’t really bother me...yet, as it will likely add more. However, the app doesn’t tell me how many unread emails I have unless I open the app. Once I do that, the badge icon updates. But once I close the app again, then the badges disappears. I really don’t want to keep opening the app to check if I have received emails. For this reason, I had to stop using this app and refer back to Spark. If they get the issues with the badge resolved, I will like go back to using this email app

We appreciate the feedback! Can you please email us at We'd definitely like to get our notifications working for you - the behavior you described is not expected. Your badge should be updating in the background.
