Ratings and reviews

Best app if you want simple and clean UI, with a ton of technical settings giving the user a very granular control over everything. The only thing that's missing is what I'm really looking for, ie. automatic sorting and prioritization of the emails based on sender, frequency of contact, etc. If you're looking for that, opt for other apps. Otherwise this is the best app. I tried like 10 of them.

Why have you gone and messed with the UI? I managed to get rid of the floating compose button, which is terrible, only to find that the text in the message list is a dull grey (I'm using dark mode). I also found that my home screen widget had been removed after the update. The pink highlights in the settings menu are terrible. I just uninstalled it, sideloaded 6.400, which is the most recent version without the UI changes, and imported my settings, which worked well.

I would have given more stars if the new version didn't introduce a lot of unused space above and below each message in the list. We're getting larger displays and better resolution every year and all UI designers do is add more whitespace everywhere.... UPDATE increasing to four stars due to the reply and the option that allows to choose yourself. But I don't know what research that is. Are people getting blinder and blinder or who is paying for that research.

What's new

Reverted changes to home screen widgets because apparently not every device vendor has incorporated the relevant fixes in Android 12+
