An app to send and receive JUST urgent messages. If it’s not a Mayday, it’s not important. We want you to find time for yourself, to be focused, to relax from all the media, and own your time. • ONE MESSAGE, ONE ANSWER. Limited messaging: Mayday is only to communicate urgent situations. You can keep talking in other apps. • MESSAGES ARE DELETED AFTER 24H. We don’t want your data. Mayday messages are encrypted, and we don’t store them: they will be erased 24 hours after they get a reply. • STAY FOCUSED. Give your notifications a rest, knowing that if there’s something important you need to be aware of right now, you will. This is the first version and we are still polishing things up, so stay tuned for exciting updates!
