A daily check-in that stays simple.

The idea behind the daily check-in is older than the smartphone. Since the late 19th century, railway engineering has used what is called a "dead man's switch": the train driver has to press a pedal or lever at regular intervals. If that confirmation is missing, the train brakes automatically. The principle is simple — anyone who is able to act can give a quick signal. Corlo carries this idea from the technical world into personal safety: instead of a lever, one tap per day — and instead of an emergency brake, a notification to a trusted person. The person at the centre actively confirms that everything is fine, rather than being watched by sensors. That is also the difference from a classic medical alert pendant. A pendant waits for a button press during the actual emergency — exactly the moment when the person may no longer be able to press anything. A daily check-in inverts the logic: as long as the person can do the short tap, everything is fine. If the tap is missing, the notification starts in the background. Both approaches have their place, but for many people who live alone without acute care needs, the active routine is the better fit.
