CanaryEcho

CanaryEcho is a wellness check-in service that keeps the people who matter informed — automatically.

What is a Signal? A Signal is a recurring check-in with a deadline. You set the cadence (hourly, daily, weekly, or monthly), and CanaryEcho tracks whether you checked in on time. Miss a deadline, and your public web status page changes from green to red — visible on the web to anyone you've shared the link with, no app required.

How it works:

Create a Signal and set its cadence. Tap "Check In" before each deadline. Share your public web status URL with loved ones, colleagues, or your audience — they can bookmark it and check anytime from any browser. Perfect for:

Anyone living alone or traveling solo Elderly family members who want to stay independent but connected Remote workers and digital nomads Warrant canaries — cryptographic proof you haven't been compelled to silence Service uptime monitoring via the API Privacy, not surveillance:

Sign in with Apple — no password required Passkey support for fast, phishing-resistant access No tracking SDKs, no ad networks, no third-party analytics, no data sold or shared Your data is encrypted at rest and in transit Free: All core features are free. If CanaryEcho gives you peace of mind, you can buy me a coffee at buymeacoffee.com/computerdna — no subscription, no pressure.
