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.
