Days to go, a clock that ticks down to the second, and one-tap check-ins confirmed by our server.
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. If you miss your deadline, we remind you on your phone. If you still don't check in, the people you chose get an email with the message you wrote.
• Check in with one tap: in the app, from a widget, a notification, Siri or Control Center
• A live countdown shows exactly how long you have
• See when your contacts would be emailed, and who
• Every check-in is confirmed by our server, so what you see is what will happen
• Reminders every day and before your deadline
• Write one message for everyone, or a personal one for each person
• If you check in after an alert, your contacts hear that you're OK
Use it for solo hikes and travel, living alone, health conditions, or peace of mind for the people who care about you.
Dead Man's Switch is not an emergency service. If you are in danger, call 911 or your local emergency number.
You can now rate Dead Man's Switch from Settings. If it's been useful, a rating helps other people find it.
New in 2.1: a calmer, clearer Dead Man's Switch.
• A new night-sky home screen: days to go, and a clock that ticks down to the second
• See exactly when your contacts would be emailed, and who
• Check in with one tap in the app, from a widget, a reminder notification, Siri, Control Center or the Action Button
• Every check-in shows the moment our server confirmed it. If one doesn't go through, you'll see that and your deadline stays put
• A push on your phone when your deadline passes, and a last call an hour before anyone is contacted
• If your contacts were alerted and you then check in, we email them that you're OK
• Send your contacts a test email so they know what an alert looks like
