It offers a fully functional email solution (email, calendar, contacts), but with the added benefits of PGP encryption support (you can handle the keys or let them do it). It also allows you to send links to people who don't use PGP if you want to send private messages. For the encryption, it's a bit like Protonmail. For everything else, it's like a privacy-respecing Gmail alternative. JohnFastman • Dec 2016 Disagree   Agree

App ever coming? Tutanota is way ahead

Comment by Robino
about ProtonMail and Tutanota Apr 2015

Protonmail is promising apps since its start a year ago. They even made it part of their crowdfunding campaign. Where did the money go? There's still no apps! I'm tired of waiting, switching to Tutanota now.
