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.
Web companion: canaryecho.com — full dashboard, public web status pages, FAQ, and API docs.
Ratings & Reviews
• Share to Instagram Stories — tap Share to send your signal's current status to the Stories composer as a branded card, ready for you to post.
• Quick share menu — copy the link or share to X, Facebook, WhatsApp, Email, or via the iOS share sheet, from any signal.
• Faster status updates — the badge on a signal's detail screen now refreshes the instant a deadline passes, with no pull-to-refresh needed.
