Building an encrypted calendar is at the top of our to-do list right now as we desperately need a solution to schedule and share calendar entries securely ourselves. However, first, we have to finish the new client to push it our of beta and update the Tutanota Android and iOS apps so that you can use your encrypted mailbox with very good speeds and many more features on all your devices.
