CheckOnce – Minimalist daily check-in app with automatic alerts

Summary: CheckOnce is a daily check-in app designed for people living alone or away from loved ones. Users tap a button once per day, and if no check-in occurs within 48 hours, emergency contacts receive an automatic email notification. It operates without location tracking or intrusive monitoring.

What it does

CheckOnce provides a one-tap daily check-in with a 48-hour countdown timer and sends automatic email alerts to emergency contacts if the user misses a check-in. It includes optional daily reminders and prioritizes user privacy by avoiding location tracking.

Who it's for

It is intended for solo travelers, digital nomads, elderly individuals living independently, and anyone living alone or far from family.

Why it matters

CheckOnce addresses the challenge of ensuring safety without intrusive check-in calls or surveillance by notifying contacts only after prolonged inactivity.
