Profile

I built this for myself after realizing that as someone who spends time alone, there was no simple way to ensure someone would be notified if something happened to me.The idea is straightforward: you check in on a schedule you set (daily, weekly, or a custom interval). If you miss your deadline, the system automatically notifies your emergency contacts via email and SMS. You control the grace period before alerts go out.It's a Node.js/Express backend with a PostgreSQL database, PWA frontend, and Web Push notifications. No app store required.It's in early beta — invite only for now while I work out the kinks.Happy to answer questions about the technical implementation or the product itself.

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

The company is listed at the Show HN launch stage of development.
