About Beacon Safe and Eloquent JavaScript

In their own words, as submitted to SaaSHub.

Beacon Safe
EJS
Eloquent JavaScript

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...

Possible disadvantages

  • Steep Learning Curve
    Some readers may find the book's progression to be rapid, especially if they are complete beginners. The book quickly moves from basic to more complex topics, which can be overwhelming.
  • Lacks Visual Aids
    While the text is clear and the code examples are helpful, the book could benefit from more visual aids like diagrams and illustrations to explain complex concepts.
  • Assumes Some Prior Knowledge
    Although it's aimed at beginners, the book sometimes assumes that readers have some prior programming experience, which can make it less accessible to absolute novices.
  • Limited Coverage of Latest ES Features
    The book may not cover some of the latest features and best practices introduced in newer versions of JavaScript (e.g., ES2019 and beyond), meaning readers might need to supplement their learning with additional resources.
  • Web Development Sections Could Be More Detailed
    While the book does touch on web development, the sections on this topic are not as in-depth as some readers might hope. Those looking to get a more thorough grounding in web development may need to consult other sources.

Questions & Answers

As answered by people managing Beacon Safe and Eloquent JavaScript.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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
