I’m enjoying the app! I would give the app a 5 star rating if push notifications actually worked. I enabled it but the alerts don’t show up on my lock screen, nor do they show up on the notifications center. If you guys would get that fixed, I would be happy to change the rating from a 3 star rating to a 5 star! 🔥

Hi Korita,
thanks for the review. The push-issue has been haunting us for a while now, but we are on it!
Best, OX Mobile Team

Not bad but needs features to be useful

Everything there works for me- it's just that there's not a lot there. To be a daily driver it needs:

Integration with the iOS sharing API like pretty much all other email apps.

Ability to create/delete folders.

Turn on/off Conversation view.

Avatar service (Gravatar is probably most logical choice... this may be up to the OX instance administrator though)

Server-side search via some search api that streams matches to your device as they're found. Currently search only matches terms against what you've synced to your device - which is fast, but not terribly useful.

Some connective tissue to manage OX contacts, calendar, tasks and drive would be nice- preferably in the form of sibling apps to adhere to the "do one thing well" principle.

In short, it has much promise in the sense that what is here, seems solid enough. That's worth 4 stars in my mind. Solve the above issues and I think this would become a pretty competitive mobile email client.

Push notifications are 4x more

I don’t want to remove the email notifications but it’s getting annoying when I see the same email pushed 4x even when I’m opening the email. Other than that it seems fine. The storage isn’t really big so make sure you delete emails if you’re really expecting high volumes.
