Not sure if this is because I only tried the free version for a month. Features seem good and handled multiple accounts from different sources. However logging in the first time I used a complicated secure password. After 48 hours was logged out. Looked like my settings had all gone. Logged in and all my accounts reappeared so not much of a problem. 48 hours after that I have 32 notification from emails to check and I have to log in again. Seems every time I close the app, it loses my login.

I love this app on iOS. This version is clearly watered down, with less resources allocated to it's development and improvement. Sad as I am a paying customer. For example, why is Helvetica not a font option? You have to choose between a small list of obscure fonts. There is a bug with the unread emails. You read them on your iPhone or desktop and they still show as unread hours later on the Android app. Please fix these annoying bugs.

In theory should be a lovely app and I've been willing to pay for the app for the last two years. However, I'm starting to question this as it's really quite buggy and slow to load emails - every time it opens takes 4 or 5 seconds to go from you've reached inbox zero to opening the emails. Often when copying in text it then struggles with keyboard placement and you have to type almost blind. And in the last few days the app keeps crashing. When the basics are wrong. Hurts everything.
