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 • On Apple Watch: see the time left on your watch face and check in from your wrist • 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 • Every day by a set time: pick a time, say 9 PM, and that's your deadline every day. Checking in early doesn't move it 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 • When you add someone, they get one short heads-up email from us, so a real alert is never a surprise (you can switch it off) TEXT ALERTS (US AND CANADA) • Your contacts can get a text as well as the email, once they say yes with one tap • Texts come in small packs.

A check-in needs an internet connection to count, because our server is what alerts your contacts if you go quiet, so it has to hear that you're OK. The app has been rebuilt since your review: it now tells you clearly when a check-in didn't reach us, keeps your deadline where it was, and lets you check in again with one tap from the app, a widget or a notification once you're back online. If you give it another try and anything goes wrong, please reach us at aaon.pro/support. aaon ## Frequently asked questions about Dead Man's Switch ### What is Deadman Switch used for?

A check-in counts once our server confirms it, just like on your iPhone. • Every day by a set time: one deadline at the same time every day, so checking in early doesn't move it. Choose it in Settings under Check in every. • Reminders first: when you turn the switch on, the app now shows you what a reminder looks like before iOS asks, so you don't miss a check-in by accident. If notifications are off, it tells you and opens Settings. • Let them know: when you add someone, they get one short email from us saying you listed them, so a real alert is never a surprise and they can make sure it doesn't go to spam. It's on by default; switch it off for anyone you'd rather tell yourself. • The widget is easier to read from across the room: a bigger countdown and a full-width Check in button. It also looks right on Tinted and Clear home screens. • Small grey text is brighter and easier to read, including the times on your timeline. • New at the bottom of Settings: More apps from aaon, the maker of Dead Man's Switch. • Now in French, Italian and Dutch too. • Uses UK words like Control Centre and Customise. ### 2.3 — 2026-10-14 What's new in 2.3: • Text alerts in the US and Canada: your contacts can get a text as well as the email. They say yes with one tap on a link you send them. Texts come in small packs; emails stay free. • Now in German and Polish too. • The widget's Check in button shows your new time right away. • Works better with VoiceOver: every screen reads the way you'd say it. ### 2.2 — 2026-10-08 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. ### 2.1.1 — 2026-09-29 You can now rate Dead Man's Switch from Settings.
