Fitbit · AI-powered primary care

Your Fitbit tracks your health signals. Clara reads them against your full medical picture.

Clara syncs your Fitbit heart rate, sleep, and activity data alongside your medical records, medications, and labs. When patterns intersect with something clinical, a physician reviews every action. Free to start.

Get started How it works

My Fitbit shows my resting heart rate has been creeping up for the past month. Is that something to look into?

Clara

I can see the upward trend in your resting heart rate over the past 5 weeks. Looking at your chart, your thyroid labs are due for a follow-up and your last TSH was at the upper end of normal. A rising resting heart rate can sometimes reflect a change in thyroid function. I'll flag this for physician review and recommend updated labs.

Values and scenarios shown are illustrative examples only. All clinical assessments are individualized and reviewed by a licensed physician.

How it works

Connect your Fitbit and your records. Clara reads them against your chart.

Connect your Fitbit and your medical records

Clara syncs your Fitbit data — heart rate, sleep stages, activity, SpO2, and steps — alongside your medical records from 150,000+ doctors' offices, hospitals, labs, and pharmacies. Free to start, no credit card required.

Clara reads your Fitbit trends against your full chart

A rising resting heart rate looks different when your thyroid labs are trending abnormal. Disrupted sleep looks different when you started a new medication last month. Clara reads these together — reading your Fitbit data in the context of your chart, not in isolation from it.

Physician-reviewed care when the pattern warrants it

When a pattern in your Fitbit data intersects with something clinical, Clara drafts a summary and routes it for physician review. Every lab order and prescription is reviewed and signed by a licensed physician before you receive it.

What Clara watches for

The Fitbit signals that don't show up at your annual physical — and what they may correlate with.

Resting heart rate trends

A sustained upward trend in resting heart rate over weeks may warrant clinical evaluation. Clara reads this signal against your thyroid labs, cardiovascular history, current medications, and recent diagnoses to identify patterns that may correlate with an underlying condition and flag them for physician review.

Sleep disruption and overnight SpO2 variation

Fragmented sleep and significant overnight drops in SpO2 can be associated with conditions including sleep-disordered breathing. Clara reads these patterns against your chart and flags multi-night trends that may warrant evaluation by your physician. Note that Fitbit's SpO2 sensor is not an FDA-cleared diagnostic tool for sleep apnea; physician evaluation and appropriate testing are required for diagnosis.

Activity decline and recovery patterns

A meaningful decline in daily steps, active minutes, or heart rate variability over several weeks can reflect changes in health status or medication effects. Clara reads activity trends against your medication list and recent labs to surface patterns that may be clinically relevant, rather than attributing them to lifestyle alone.

The AI difference

What an AI that reads your full chart makes possible in primary care.

A clinician in a 15-minute visit reads the last panel. Clara reads every result you have ever had drawn — every lab, every wearable reading, every medication change — and cross-references them in a single pass. The AI handles the data; licensed physicians handle every clinical decision.

Reads your entire chart, every time

Clara auto-syncs from 150,000+ medical sources and reads every prior result, medication, and diagnosis together — including your Fitbit data. Pattern-finding across years of data is what the AI is built for.

Cross-reads device data against your meds and labs

A new medication can shift your resting heart rate or disrupt your sleep. A drifting lab value can show up in Fitbit trends before you feel symptoms. Clara reads expected pharmacology against actual wearable data — catching drug effects that aren't pathologic, and flagging ones that are.

Physician review on every clinical action

Clara drafts; physicians decide. Every lab order and prescription is reviewed and signed by a licensed clinician. The AI handles intake, reasoning, and follow-up. The physician handles every sign-off.

Common questions about Clara.

What does Clara cost?

Connecting your medical records and chatting with Clara is free. Subscription plans start at $25/month (Basic), which includes physician-approved prescriptions and lab orders. Standard ($50/mo) includes 74 biomarker tests and wearable integration, including Fitbit. Concierge ($150/mo) includes 108 biomarker tests and expanded panels. All plans are HSA/FSA eligible and cash-pay. Medications are billed separately by your pharmacy.

Can I use my insurance, HSA, or FSA?

Clara's membership is cash-pay and not billed through insurance, but every plan is HSA/FSA eligible. Prescriptions Clara's physicians write go to your pharmacy and may be covered by your plan. Ad-hoc lab orders may also be covered by your insurance when applicable.

Is Clara a real medical practice?

Yes. Clara operates through affiliated professional corporations 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. The physician sign-off happens before any clinical action reaches you.

How does Clara use my Fitbit data?

Clara syncs your Fitbit data — resting heart rate, sleep stages, SpO2, steps, and activity — and reads it alongside your full medical chart: current medications, recent labs, prior diagnoses, and anything else in your record. When a multi-day or multi-week pattern in your Fitbit data intersects with something clinical, Clara surfaces it for physician review. Your Fitbit data is one input among many — not a standalone diagnostic tool.

Can Clara diagnose sleep apnea from my Fitbit SpO2 data?

No. Fitbit's SpO2 sensor is a consumer-grade optical sensor and is not an FDA-cleared diagnostic tool for sleep apnea or any other medical condition. Clara reads overnight SpO2 variation as one signal among many and may flag patterns that warrant evaluation. Diagnosis of sleep apnea requires a physician evaluation and appropriate sleep study. Clara can facilitate a referral if the clinical picture warrants it.

Is my Fitbit data covered by HIPAA once Clara connects it?

Yes. Once Clara syncs your Fitbit data as part of your medical record, it is covered by HIPAA and subject to the same privacy protections as any other health information. Your data is not sold to third parties and is not used to train public AI models.

What if I need in-person care?

Clara refers to in-person providers for physical exams, imaging, and any care that cannot be safely delivered remotely. Clara prepares a clinical summary and referral letter for every handoff so the receiving provider has full context.
