Olkano

Olkano is a daily "I'm OK" check-in for people who live alone. Set a time, tap once to confirm you're OK, and if you miss a check-in your trusted contacts get an alert. No location tracking, no wearables. Works in reverse of emergency buttons: it acts on the absence of a check-in, not a press during a crisis. Free with one contact, Plus for unlimited. iOS and Android.
