CERRET's bracelet looks like fine jewelry, but the safety feature underneath depends on a specific chain of steps: your phone, the CERRET app, and a Bluetooth connection. Here's exactly how setup, alerts, and cancellation work -- including where the system depends on your phone, so you know what to expect before relying on it.

Quick Verdict
In short: pair the bracelet to the CERRET app over Bluetooth, add trusted contacts, and a double press of the button sends them a text, your live location, and an automated call. The bracelet itself has no independent connectivity -- it works only through your paired phone, so understanding that dependency matters more than any other feature here.

Download the CERRET app
Available for iOS 26+ and Android 16+. This is required -- the bracelet has no independent connectivity of its own and cannot do anything without the app installed and running on a paired phone.

|
Pair the bracelet over Bluetooth
Connects within a range of up to 50 feet (15 meters), depending on conditions. Pairing is a one-time setup step.

Add your trusted contacts
Choose who should be alerted in an emergency. CERRET does not publish a specific numeric limit on how many contacts you can add.

|
4
|
Keep the app running and your phone charged
The bracelet depends entirely on your paired phone to actually send an alert -- see the dependency section below before you rely on this day to day.

|
Press the emergency button twice
A double press is required, specifically to reduce accidental alerts -- CERRET also designed the button to sit flush with the wristband so it's harder to trigger by leaning on it or resting your arm.

The bracelet signals your paired phone over Bluetooth
The bracelet itself has no cellular radio or GPS chip -- it relies entirely on the Bluetooth connection to your phone and the CERRET app running on it.

Your contacts receive a text, your live location, and an automated call
Per CERRET's own FAQ, pressing the button "triggers an emergency call to your contacts" and "sends them a text message notifying them of your whereabouts, including a link to your precise real-time location." CERRET markets this call as "Voice Activation" on its homepage.

|
You have 15 minutes to cancel from the app
If the alert was triggered by accident, you can cancel it from within the CERRET app during this window.

This is the single most important thing to understand about how CERRET works: the bracelet cannot send an alert on its own. It has no cellular radio and no GPS chip built in -- every alert depends on a working Bluetooth connection to a phone that has the CERRET app installed, running, and within roughly 50 feet (15 meters).
The bracelet runs on a single replaceable CR1216 coin-cell battery rated for 24-30 months, and the CERRET app will alert you once it drops below 50% so you can swap it before it dies -- an important detail given how much the alert workflow depends on the bracelet actually having power. It carries an IP53 water-resistance rating, meaning rain and light splashing are fine, but showering, swimming, or submersion are not.

Press the emergency button on the bracelet twice in quick succession. A double press is required by design, to make accidental alerts less likely.
Per CERRET's own FAQ, your contacts get a text message with your whereabouts, a link to your real-time location, and an automated emergency call (what CERRET calls "Voice Activation" on its site).
No. The bracelet connects to your phone over Bluetooth (up to 50ft/15m) and depends entirely on the CERRET app running on that phone to send any alert. It has no independent cellular or GPS connection of its own.
No, not by default. Based on everything published on CERRET's own site, the bracelet alerts the personal contacts you've added -- not 911 or a professional monitoring service.
Yes. You have up to 15 minutes to cancel the alert from within the CERRET app.
24 to 30 months on a single CR1216 button-cell battery, which is user-replaceable. The app will notify you once the battery drops below 50%.
It's water-resistant to an IP53 rating -- fine for rain and light splashing, but not rated for showering, swimming, or submersion.
