Proton Mail’s offline mode
Proton Mail’s free apps for Android (www.snipca.com/55324) and iOS (www.snipca.com/55325) encrypt the emails you store on your phone or tablet, making them more secure than Gmail and Outlook. They’ve just been relaunched to work in offline mode, letting you read, write and organise emails without an internet connection. Your emails sync automatically once you’re back online (see screenshot).
