K-9 mail is a very good email app. It's easy to set up, and has all the options the average user needs. Could it use a few changes? Yes, instead of using the bottom of the screen for downloading the entire message, I believe the delete button at the bottom would be more useful and easier to use than having it offset at the top of the screen. I've used canine mail many years ago and lost track of it. I'm glad that I have found it again. Great job developers!

Thanks for the nice review, Tim. And also for your feedback about the placement of the delete icon.

It crashed many times during setup. Can't get passed setup. Edited: After numerous attempts I identified the step at which the setup was crashing. After typing the password to log into my email account, making the PW visible would crash the app. Finally, I set it up. Nice app, simple, not many bells and whistles, works well with Google, Microsoft.

For me one of the fewer emails cliënts that pretty much always work AND has a nice UI. There was 1 thing that didn't work recently tho. I wanted to add a couple of photos to an email, but everytime i tried that, the app stopped working. It was litterally impossible to add. Everything else worked, and i gave the app all permissions required to add photos. Is this a bug or have i missed something?
