About this app

You live alone and that is a good thing. But what if something happens and no one notices?

Corlo is a life-sign check-in app for your home. It reminds you of your daily check-in. One tap is enough. If you don't respond – for example because you are unconscious or need help – your emergency contacts are alerted automatically.

You might know the principle as a dead man's switch from trains and industry. In Corlo it's the other way round: you actively give a sign of life. Gentle, personal, no pressure.

NEW: SMS ALERTS ON THE LOCK SCREEN
With Family Mode + SMS, your emergency contacts also receive a flash SMS directly on their lock screen – even when they're not checking their inbox.

HOW CORLO WORKS:
• simple setup, no registration – no account, no login
• daily check-in with a single tap
• automatic alert if you don't respond
• personal message to your emergency contacts
• 2 alarm windows: 24 or 48 hours
• 100 % GDPR compliant, servers in Frankfurt

WHAT MAKES CORLO DIFFERENT:
Radically simple. Other life-sign apps offer NFC tags, widgets, quick actions, SOS buttons, medical profiles, intervals from 12 hours to a month – and setups that take half an hour. Corlo has two profiles and one tap. In an emergency, simplicity is a safety feature: an app you understand is an app that works when it matters.

No user account. You install, set up, done – no Apple, Google or email sign-in. Your identity stays on your device.

Escalation if the first contact doesn't react. In Family Mode, additional alerts are sent automatically after 2 and 6 hours – in case your first contact is asleep, at the cinema, or has the phone on silent.

WHO IS CORLO FOR?
• People who live alone (singles, students)
• Older adults and seniors who want to maintain their independence
• Solo travelers, backpackers, outdoor enthusiasts, and students studying abroad
• Family members who want a discreet safety net—without daily phone calls
• Anyone who wants to play it safe

ALTERNATIVE TO A HOME EMERGENCY CALL SYSTEM:
Traditional home emergency systems need a fixed base station, monthly fees and contracts. Corlo uses the smartphone you already carry – at home, outside, in the garden, on holiday. No hardware, no landline, no contract hassle. In the free version with no recurring cost at all.

PRIVACY:
No user account, no tracking, no ads. Your data stays in Europe.

Note: Corlo is not a medical device, an emergency service, or a substitute for calling emergency services or a professional in-home emergency response system. The app sends reminders and notifications to your saved contacts, but cannot guarantee assistance.

What’s new

In addition to email, your emergency contacts can now be alerted via text message - including as a flash SMS that appears directly on the lock screen.
Available as the new “Family Mode + SMS” subscription in Settings.
