We turn health data into one step a day

People connect their medical records, wearables and labs in one place. Each day, we give them one step that fits their whole health, including any conditions or medicines.

Today's focus: hit 6,000 steps, done. Goal crushed, with room to spare!

40,000+

doctors’ offices, hospitals, clinics and insurers people can connect

Hundreds

of devices and apps, through Apple Health

People can connect the devices and apps they already use, and their records from hospitals, doctors' offices and insurers.

The problem

People have more health data than ever and little help using it

59%

of US adults have records in more than one patient portal. Only 7% use an app to pull them together.

What we built

People see everything in one place and get one step to take each day

Home

A score for heart, fitness and mind, and one step to take today that accounts for any conditions or medicines.

Story

Each week, people see what changed and what's working.

Record

Labs, medicines, conditions, visits and daily numbers are all in one record.

Why it lasts

A health record is only worth as much as how long people stay

There's a reason to open it every day

People usually open a records app before a doctor's visit. We give them a step to take every day, so they keep adding to their record between visits.

A pattern found in someone's own data: longer sleep on nights that start earlier

We don't let AI decide what's true

Tested rules decide what's true about a person's health. AI only writes the sentences, and we check each one before anyone sees it, so a newer model doesn't change the answers.

People sign in on their own health system's site

We connect straight to each record system

We use each system's own patient access, so we don't pay a middleman for every record.

Trust

We follow the rules health apps are held to

We never diagnose or treat

We suggest a step to take or a question to ask a doctor.

Research is opt-in

Sharing for research is off until a person turns it on. Sharing records from a health system takes a separate yes.

We log every consent

Face ID locks the app, and we log every record connection and consent.

Our scoring method is public

We publish how we score, with sources, on our How we score page.
