What Safety Checkpoint adds

Encryption for each contact

Kitestring sent plain-text SMS. Safety Checkpoint encrypts your emergency message and saved credentials separately for each contact, and only that contact's PIN opens them.

Multi-channel alerts

Kitestring was SMS-only. Safety Checkpoint alerts by email on every plan and adds SMS on Survival. Each contact can choose their preferred method.

Rich emergency context

Add medical details, door codes and emergency instructions to your check-in protocol, and documents on paid plans. With their PIN, your contacts open everything they need to help.

Frequently asked questions

Short answers first. Each one links to where the detail lives.

What happened to Kitestring?

Kitestring was a web-based check-in service that sent you a text at a scheduled time. If you did not reply, it texted your emergency contacts. The service has since shut down. Safety Checkpoint is a modern alternative that builds on the same concept with encryption, multi-channel alerts, and file attachments.

More detailLess detail
  • Kitestring was SMS-only and web-based
  • It has shut down and is no longer available
  • The core concept was simple: check in or your contacts are alerted
  • Safety Checkpoint continues this concept with modern encryption and features
  • No data migration is needed since Kitestring no longer exists

How is Safety Checkpoint similar to Kitestring?

Both share the same core concept: you set a check-in time, and if you do not respond, your emergency contacts are notified. Safety Checkpoint takes this further with emergency messages encrypted for each contact, file attachments, multi-channel alerts (email, plus SMS on Survival), and recurring protocols.

More detailLess detail
  • Same core concept: check in or your contacts are alerted
  • Safety Checkpoint adds encryption that Kitestring never had
  • Email alerts on every plan and SMS on Survival, instead of SMS-only
  • File attachments: medical details, itineraries, emergency documents
  • Recurring protocols for daily, weekly, or custom schedules

Is Safety Checkpoint free like Kitestring was?

Paid plans start at Safety 101 ($4.99/mo) for recurring protocols, more contacts and encrypted storage. SMS and email together are on Survival ($9.99/mo). Kitestring was free but limited to SMS and had no encryption.

  • Email alerts on every plan, plus SMS on Survival
  • Encrypted credentials: door codes, safe combinations, account access

Are there other Kitestring alternatives?

Several apps address similar needs: Snug (daily check-ins for seniors), bSafe (SOS button with guardian alerts), and Life360 (family GPS tracking). Safety Checkpoint is the closest modern equivalent to Kitestring's original concept: scheduled check-ins with automatic alerts on missed response.

More detailLess detail
  • Snug: daily check-ins for seniors with an optional dispatcher plan
  • bSafe: SOS panic button with real-time location sharing
  • Life360: family GPS tracking with driving reports
  • Safety Checkpoint: scheduled check-ins with encrypted emergency context
  • Safety Checkpoint is the most direct successor to Kitestring's check-in model

Can I set up Safety Checkpoint as simply as Kitestring?

Yes. Creating a basic check-in protocol takes a few minutes: set a title, pick a check-in time, add your emergency contacts (they accept an email invitation), write your emergency message, set your personal PIN, and activate. The simplicity of Kitestring's model is preserved, with optional advanced features for those who want them.

More detailLess detail
  • Basic protocol setup takes a few minutes
  • One-tap check-in confirmation when prompted
  • Simple emergency message or detailed medical context, your choice
  • Optional file attachments and encrypted credentials for advanced users
  • Start simple, add complexity only when you need it
