In their own words, as submitted to SaaSHub.

Beacon Safe is a personal-safety check-in app — a modern dead man's switch. Set a daily check-in; if you don't confirm, it reaches your emergency contacts by email, SMS, then an automated voice call in a four-phase escalation. Unlike Kitestring, Snug Safety, or bSafe, it never tracks your...

As answered by people managing Beacon Safe and Eloquent JavaScript.
Beacon Safe's answer
Three real alert channels — email, SMS, and an automated voice call — instead of one. The check-in timer runs on our servers, so alerts still fire if your phone is dead, off, or lost. And it never tracks your location; it only acts when you miss a check-in.
Beacon Safe's answer
Unlike Kitestring (discontinued), single-email tools, or $15–20/mo apps, Beacon Safe reaches your contacts across email, SMS, and voice in a four-phase escalation, runs server-side so it works phone-off, and costs $7.99/mo. No location tracking, ads, or data sale.
Beacon Safe's answer
People who live alone, solo travelers, night-shift and lone workers, and seniors — plus the family members who worry about them. Anyone who wants someone alerted automatically if they go silent.
Beacon Safe's answer
After Kitestring shut down, the remaining "check in or we alert someone" options were either single-channel or expensive. Beacon Safe — built by Copperline Labs, a solo studio — is the version that does email + SMS + voice, runs server-side, and respects privacy.
Beacon Safe's answer
Beacon Safe is a native iOS and Android app backed by a secure server-side system that runs the check-in timer and fires alerts. We use established, compliance-grade infrastructure for SMS, voice, and email delivery. All data is encrypted in transit and at rest, we collect no location data, and we never sell or share your information.

Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
