Great concept, no updates.

Still love the Unibox concept but the app just does not work well. Slow to update, emails not syncing, infrequent developer updates to the app and notifications that simply don’t work. I don’t use anymore but keep it around just hoping someday the updates will fix most of the issues and get push notifications working. If you are coming from the Mac app that also has many issues, I would save yourself $5 and walk away.

Version 1.1 update:
Had deleted the previous version as the updating just did not work for me. I still use OSX version and love the concept. I want to like the iOS version. The search function is much improved and also spotlight search is a great addition. For this to be my everyday email client, and I really want it to be, I need them to add an option for push notifications. I simply have to many emails that need to have attention quickly. I will keep using it, but still some bugs to work out. Overall good improvement from V1. Hoping for more updates with a quicker timeline than 1 per 8-9 months.


Icons/grouping great; replying/forwarding clunky

The icons and the grouping are great and make searching through your email to prioritize what you want to look at easier. However answering and forwarding emails is a little clunky, so I generally go over to my other email program to do that.


Best so far

I’m trying to find a reasonable Email program where I can organize things so far I haven’t found anything much better than this
