  • •PWA + Web Push means no app store friction, works across devices
Weaknesses
  • •Invite-only early beta provides no signal on actual product-market fit or retention
  • •Regulatory uncertainty: SMS/email alert delivery, emergency contact liability, GDPR compliance unaddressed

Post Description

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.

DayTap – A privacy-first dead man's switch iOS app

The UX is delightfully minimal — one big "I'm OK" button, configurable guardians, and a check-in window — and the author leaned on Claude Code plus multi-role LLM reviews to shore up gaps in their Swift work, which is an interesting workflow experiment. The privacy-forward touches shown on the landing page (encrypted, no GPS) are promising, but critical backend details and delivery guarantees are missing, and the core idea is familiar rather than novel.
