knokkeroo

knokkeroo is the simplest way to tell the people who care about you that you're okay — and to keep a gentle eye on the people you care about.

Tap "Knok" once a day to check in. The people who watch over you see at a glance that you're fine. If someone you watch hasn't checked in within their chosen window, you'll know to reach out.

HOW IT WORKS • Tap Knok to check in — that's it. • Add the people you care about. When they accept, you watch over each other. • Everyone appears as a simple traffic-light tile: green (recently checked in), amber (due), red (overdue). • Set your own check-in interval and quiet hours, so you're never nudged at the wrong time. Each person's time is shown in their own timezone.

WHO IT'S FOR • Older parents and their adult children staying in touch. • Friends and family who live alone. • Anyone who wants a low-effort way to say "I'm okay" without a phone call.

PRIVATE BY DESIGN • No social feed, no ads, no tracking. • You only ever share your status with the people you approve. • Delete your account any time, right from the app — it removes your data and frees your number.

IMPORTANT knokkeroo is a personal check-in and communication tool. It is NOT a medical device, emergency response system, or a substitute for professional or emergency services. If someone is in immediate danger, contact your local emergency services right away.
