New in 2.2: • Away: going somewhere without signal? Pick the day you'll be back. Nobody is emailed before then, and daily reminders pause until shortly before. • Dead Man's Switch now speaks Spanish: the app, widgets, reminders and Siri. If you use the app in Spanish, your contacts get their alert emails in Spanish too. • Bigger text: Home and Settings follow your iPhone's text size, and the check-in button always stays on screen.
Dead Man's Switch checks that you're OK. Choose how often you'll check in, anywhere from once a day to once a year. Miss your deadline and your phone reminds you. Still no check-in after the grace window, and the people you chose get an email with the message you wrote. It's for anyone who lives alone, hikes or travels solo, has a health condition, or wants the people who care about them to know if something is wrong. CHECK IN WITH ONE TAP • From the app, a widget, a notification, Siri, Control Center or the Action Button • A live countdown shows exactly how long you have, down to the second • Every check-in is confirmed by our server, so what you see is what will happen KNOW WHAT HAPPENS, AND WHEN • See when your contacts would be emailed, and who • Reminders every day and before your deadline • A grace window before anyone is emailed • Send a test email so your contacts know what to expect • If you check in after an alert went out, your contacts get an "all clear" email YOUR MESSAGE, YOUR PEOPLE • Write one message for everyone, or a personal one for each person • Your contacts don't need the app. They just get an email AWAY MODE • Going somewhere without signal? Pick the day you're back, and nobody is emailed before then PRIVATE BY DESIGN • No account to create • No location tracking Available in English and Spanish. Dead Man's Switch is not an emergency service and does not contact emergency services. If you are in danger, call 911 or your local emergency number.
