Features/Vital alerts

Three alerts. You set the numbers.

The ring watches your heart rate and your blood oxygen while you wear it. If either crosses a limit you chose, the alert is logged — and on Ring 1 the ring vibrates on your finger. Three alerts, your thresholds, and a list of what happened.

Vibration is available on Circular Ring 1.

The whole list

What it can alert you on.

High heart rateTriggers when your bpm is equal to or goes above the value you choose. The default is your Max HR.
Low heart rateTriggers when your bpm is equal to or goes under the value you choose. The default is your resting heart rate minus 10 bpm.
Low blood oxygenTriggers when your SpO₂ reaches the percentage you choose. The default is 94%.

Three alerts is the list. The ring does not alert on temperature, breathing rate, rhythm or sleep, and it does not decide anything is wrong — it tells you a number you chose was crossed, and when. Every alert is logged in the app, and on Ring 1 it also vibrates.

Settings

Turn each one on, and pick its number.

Each alert has its own switch and its own trigger, so you can run one, two or all three. The app fills in a default for each, and you can move it or reset it whenever you like.

  • High HR triggerDefault 191 bpm on this account — your Max HR. Slide it anywhere and save.
  • Low HR triggerDefault 40 bpm here — resting heart rate minus 10 bpm.
  • Low SpO₂ triggerDefault 94%.
  • Reset to defaultOne tap in each trigger sheet puts the number back.

How you are told · Ring 1

A vibration on your finger, in the pattern you pick.

On Ring 1, alerts arrive as a vibration from the ring itself. You can set how strong it is, choose between seven patterns, or switch ring vibrations off and read the alerts in the app instead.

  • IntensityOne slider, applied to every alert.
  • Seven patternsAlert — the default — Heartbeat, Quick, Rapid, SOS, Staccato and Symphony.
  • Ring vibrations, offA single switch. The alerts are still logged.

Honest limits

What it will not pretend to do.

  • It does not diagnoseAn alert means a number you set was crossed. Nothing is inferred from it.
  • It is not for emergenciesNo one else is notified. If you feel unwell, call your local emergency number.
  • Three alerts onlyHigh heart rate, low heart rate, low blood oxygen.
  • Vibration is a Ring 1 featureEverywhere else an alert is a log entry in the app rather than a buzz.
  • The ring has to be on and connectedThe app prompts you to reconnect when it is not.
  • Included with the ringNo subscription, like every other measurement.
Questions

Before you switch them on.

More in the help centre.

High heart rate, low heart rate and low blood oxygen. Each has its own switch and its own trigger value.

High heart rate defaults to your Max HR. Low heart rate defaults to your resting heart rate minus 10 bpm. Low blood oxygen defaults to 94%. Each trigger sheet has a reset if you want the default back.

The alert is added to the list in the app with the reading, how far past your limit it was, and the time. On Ring 1 the ring also vibrates, if ring vibrations are on.

On Ring 1 there is an intensity slider and seven vibration patterns — Alert, Heartbeat, Quick, Rapid, SOS, Staccato and Symphony — and you can turn ring vibrations off altogether.

No. Alerts go to you and no one else. Circular is not a medical device and is not for use in an emergency.

No. Vital alerts are included with the ring, permanently.

The point is that you never have to remember to check.

Wear it, forget it, and hear about it only when there is something to hear.
