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, monthly, or one-time — say, for a trip), 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:
1. Create a Signal and set its cadence.
2. Press and hold a Signal to check in before each deadline.
3. 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 — a regular public statement that you've received no gag orders; if the check-ins stop, readers see it
• 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.
