RedReader vs FairEmail

The app is completely free and there is no tracking through advertisement since there are none. For those that are security conscious on their devices this makes a great choice for a Reddit app.

Scrolling and swiping actions make for an intuitive interface that is easy to control.

RedReader is completely open source meaning the code is available for anyone to look at or use. It's a completely open environment for understanding the app if one is so inclined.

The user interface is simple in its layout making it easy to read and use.

No ads, open-source.

Multiple identities per account, notifications per account or contact.

It is actively maintained. The used libraries are up to date and bugs are fixed quickly.

There are no trackers within the app and trackers sent with mails are disabled by default. This app lets you read and compose emails with your privacy in your very own hands.

Privacy features are excellent.

~ 20 MB.

Supports both OpenPGP and S/MIME encryption for total privacy.

Allows to configure maximum size of email downloaded immediately.

Some HTML mails may show different links and link texts, this app however will show you the real link before opening, protecting against phishing and scams

Some domain names may use non-ASCII characters looking similar to the latin alphabet (e.g. some cyrillic characters). This app will show you the punycode representation of the domain, if that is the case and thus protect you against phishing and scams.

Some HTML mails may include ressources that can track you. This app doesn't load them by default, but reformats the text, increasing both privacy and readability.

There are open standards for any email provider to show how an email client should connect to the server. This app supports both RFC 6186 as well as Thunderbird Autoconfiguration standards.

Supports authenticating with the mail server using OAuth, thus increasing security.
