Fitbit + Clara · AI primary care for your AFib Alerts, HR, SpO2 & Sleep Data

How it works

Fitbit flags the signal. Clara does the clinical work.

Connect Fitbit and your records

Clara pulls your Fitbit resting HR, continuous HR, SpO2, sleep stages, activity minutes, and Irregular Heart Rhythm Notifications, and auto-syncs your medical records from 150,000+ doctors' offices, hospitals, clinics, and labs. No PDFs, no faxed labs. Free to start.

Clara reads the stream, not just the alerts

An AFib notification is the loudest signal, but it's not the only one. Clara reads continuous resting-HR drift, overnight SpO2 dips that suggest sleep apnea, and activity-level collapse against your cardiovascular risk profile, thyroid labs, and blood-pressure trend. The context is what makes the alert actionable.

Chat, labs, or Rx when warranted

Ask Clara anything. When Fitbit flags something that warrants a workup, a licensed physician reviews Clara's plan and signs off on prescriptions or lab orders. FDA-approved prescriptions and ad-hoc lab work may be covered by your insurance.

What Clara watches

The Fitbit signals that shouldn't end at a notification.

AFib screen

Irregular Heart Rhythm Notifications

Fitbit's IHRN feature is FDA-cleared to flag patterns consistent with atrial fibrillation on supported models. It is a screen, not a diagnosis. Clara treats every alert as a prompt to order the right confirmatory test (patch monitor or ECG) and to stratify stroke risk against your full chart.

Resting HR

Resting-HR drift over weeks

A steady resting-HR climb against your own baseline flags subclinical thyroid dysfunction, anemia, deconditioning, uncontrolled hypertension, or early cardiac disease. Clara compares the drift to your last TSH, CBC, and BP, and queues the right lab recheck when the pattern warrants.

Weekly

Cadence at which Clara reassesses

Overnight SpO2

SpO2 dips and sleep apnea risk

Fitbit's overnight SpO2 variability metric is not a sleep-apnea diagnosis, but combined with your BMI, neck circumference, daytime fatigue, and any hypertension on the chart, it's a credible trigger to queue a home sleep test. Clara places the order when the pattern warrants.

Risk flag

Not diagnostic, but actionable in context

Activity collapse

Sustained inactivity or cardio decline

A 4-to-6-week collapse in daily activity and cardio zone minutes is rarely random. It maps to depression, an untreated thyroid issue, new pain, or the quiet onset of a chronic condition. Clara surfaces the inflection and queues a targeted follow-up rather than waiting for the next annual visit.

The AI difference

An AFib notification is the start of a workup, not the end.

The Fitbit app is excellent at surfacing a flag. It cannot stratify your stroke risk, order a patch monitor, rule out hyperthyroidism, or start anticoagulation. Clara does all of that against your full chart in seconds. That is the gap between wellness and primary care, and it's a structural gap a human clinician cannot close inside a fifteen-minute slot.

Turns the alert into a plan

Clara reads every Fitbit alert against your chart: BP trend, lipid panel, current medications, family cardiac history, diabetes status. The output is not "see your doctor", it's a specific workup (patch monitor, TSH, BMP) queued for clinician sign-off.

Reads 24/7 continuous HR a doctor never sees

Your Fitbit logs heart-rate samples around the clock. Clara reads the multi-week resting-HR drift against your BP trend, lipid panel, and thyroid labs. A 15-minute office visit sees one resting HR at the cuff; Clara sees the curve.

Cross-condition reasoning

Your new beta blocker will suppress Fitbit's HR reading. Your GLP-1 will bump resting HR. Your SSRI will flatten HRV. Clara with the full medication list open stops misreading expected drug effects as pathology, and catches the drug effect that actually is.

Common questions

Fitbit with Clara: the questions patients actually ask.

What does Clara cost?

Connecting your medical records and chatting with Clara is free. Wearable integration (Fitbit, Oura, Eight Sleep, Garmin, Peloton, Whoop, Apple Watch) is included with the Standard plan at $50/month, which also includes 74 biomarker tests as part of the membership (not billed separately, not billed to insurance). All plans are HSA/FSA eligible. Prescriptions Clara writes and ad-hoc lab orders are billed by your pharmacy or lab and may be covered by your insurance.

My Fitbit flagged an irregular rhythm. Is that AFib?

Fitbit's Irregular Heart Rhythm Notifications feature is FDA-cleared to screen for rhythms consistent with atrial fibrillation on supported devices, but it is a screen, not a diagnosis. A positive flag needs a confirmatory test (typically a 7-to-14-day ambulatory patch monitor or an in-office ECG), plus a workup for reversible drivers like thyroid dysfunction, electrolyte abnormalities, and alcohol. Clara reads the alert against your chart and queues the right confirmation for a clinician to sign off. If AFib is confirmed, anticoagulation and rate-or-rhythm control decisions follow, and those are individual, guideline-driven choices made with our doctor.

How does Clara use my Fitbit data?

Clara pulls your resting HR, continuous HR, SpO2, sleep stages, activity minutes, and any FDA-cleared rhythm or SpO2 alerts, and reads them against your full medical chart: current medications, recent labs, prior diagnoses, BP trend, family history. When a pattern intersects with something clinical, Clara surfaces it and queues the right next step.

Is Clara a real medical practice?

Yes. Clara is licensed in all 50 states. All diagnoses, prescriptions, and lab orders are reviewed and signed off by licensed physicians. Clara's AI handles intake, continuous monitoring, and clinical reasoning, with human medical oversight on every order.

How is this different from my regular doctor?

Can your old doctor read your entire medical chart and every heart-rate sample your Fitbit recorded this year, every time you meet with them? Clara can. And your Fitbit alerts ping into an inbox at the PCP's office that is read, at best, weekly, usually with "follow up at your next visit" as the reply. Clara reads the alert in seconds, against your full chart, and responds with an actual workup plan. For broader primary-care context, see AI primary care, hypertension, or longevity.

Can I use my insurance, HSA, or FSA?

Clara's membership is cash-pay, not billed through insurance, but every plan is HSA/FSA eligible so you can pay it with pre-tax dollars. Prescriptions Clara writes go to your pharmacy and may be covered by your plan like any other script; ad-hoc lab orders at Labcorp or Quest, and patch-monitor or home sleep study orders, may be covered when applicable. The 74-test biomarker panel bundled into the Standard plan is a separate category. That cost is included in the membership itself and is not billed to your insurance.

Is my Fitbit and medical data private?

Clara is HIPAA compliant. Your Fitbit data and medical records are used to personalize your care. They are not sold, and they are not used to train public AI models.
