What if something happens to you — and no one notices? Swan Signal is there, always and everywhere. Your contacts get alerted, by email and SMS.
If you don't check in, your loved ones will know.
Swan Signal is your daily life-sign service - a digital dead-man switch for people who live alone, travel alone, or simply want someone to notice when something is wrong.
HOW IT WORKS
1. Pick up to 3 emergency contacts from your iPhone address book.
2. Confirm once every 24 hours with your 4-digit code that you are fine - then no message goes to your contacts.
3. If the confirmation is missed for 24 hours, your contacts are notified automatically by email and SMS - with your last known location.
WHY SWAN SIGNAL
> The alert goes out - no matter what happens.
Battery dead? Phone lost? App deleted? The protection on our servers keeps running - 24/7.
> Your contacts don't need the app.
Emergency contacts receive the alert as a regular email or SMS. Nothing to install, nothing to sign up for, nothing to configure. Works on any phone, any computer, anywhere.
> Location included.
With location sharing enabled, every alert message contains a Google Maps link with your last known position. Help knows exactly where to go.
> Emergency button for instant help.
Acute emergency? Tap the emergency button, confirm with your code - alert goes out immediately. No 24-hour wait.
> Danger Zone for high-risk situations.
Climbing, diving, walking home alone, first date, solo trip? Activate the Danger Zone for 1-6 hours with a shortened countdown.
> Pause Mode when you don't need protection for a while.
Pause 1, 3, 7 days or indefinitely.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New: Choose your terminal!
• A second design, "Radio Station" – the warm amber terminal of a broadcast station, as an alternative to the classic "Bunker," the green terminal deep underground. Switch anytime – from the welcome screen or in Settings.
• Reworked color-blind mode for more distinguishable colors.
• Polished sounds and animations.
"Bunker" stays the default – nothing changes if you love it.
