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.

They don't accept new users because they haven't got enough servers. Hope it'll be fixed soon!
