Keep coming back...


I have done extensive trials with most of the other email apps out there, spark, hop, airmail, etc. But this is the email app I keep coming back to, both in my Mac an iOS devices.
I keep searching because I wish unibox had a few features that I miss from the others: 1. Calendar recognition as link and better integration of invitations. 2. Color coding of different email accounts. 3. More swipe command options. 4. Better signature platform that allows images and font changes.
Why 5 stars? Because this is the best of what is available and I can survive without my wanted features. I just hope they deliver in a future version.

Great alternative email app


I have tried all the major email apps and while they are all reasonably functional for my needs, none fit my workflow or had the visual appeal I was looking for. That is until I came across Unibox. It was not until I tried this app that I realized that grouping emails by sender instead of a chronological list of emails like other apps not only fit better with my workflow, but made me realize that this is what I was looking for all along. Kudos to the developers for creating refreshing and efficient way of working with email. Looks like my search is finally over.

Five stars if I could get integration with cloud storage and other apps like to do apps.

Buggy lately and still no dark option but I bet I can get a vhs version


Update: Noticed an update was I tried it again. A little more buggy and still no modern dark mode to save it from being a blinding battery killer. Still unusable. Great concept with not so good implementation. Original: Lately it has been buggy and cannot view email threads properly. It is also one of the few apps that still doesn't offer an alternative to the battery-draining hard-to-read white-washing theme. These days, not providing a dark theme is like offering today's new movies in vhs format. Time for the developer to catch up with consumer demands and modern times.
