Halden

Most of your health happens between doctor visits.

Halden keeps track of your blood pressure, glucose, labs and medicines. It learns what's normal for you, speaks up when something changes, and gets you ready for the next appointment.

Coming soon to iPhone and Apple Watch.

Halden's Today screen. A short brief explains this morning's blood pressure, then cards show blood pressure against the target Dr. Patel set, fasting glucose in range and an A1c of 7.1%.

  1. Visit with Dr. Patel

  2. Your blood pressure has been up 3 days running, about 142 against your usual 133. Anything going on?

    You answered: Stressed

  3. Your blood pressure is back to your normal. Looks like the stressful stretch eased up.

  4. From your recordMetoprolol added by cardiology.

  5. From your recordA1c 7.1%, down from 7.4%.

  6. Your visit with Dr. Patel is in 3 days. Visit prep is ready when you want it.

  7. Next visit. You walk in knowing what changed.

105 days between two visits, with Halden. The serif lines are Halden talking. The rest comes from your health record.

It learns your normal, then tells you when you're off it.

Halden compares you with you. After a couple of weeks it knows your usual resting heart rate, sleep, blood pressure and glucose. When one of them drifts for a few days in a row, it asks what's going on.

Tap an answer like Stressed, Sick or Traveling. Halden remembers it. It tells you when things settle, and next time it reminds you how it went the last time.

Most days it says nothing at all. You choose how often it can check in: quiet, balanced or more.

Ranges that fit your conditions and medicines.

A blood pressure of 134/84 means something different for everyone. Halden reads it against the target your care team set, not a number from a poster.

It knows what your medicines do, too. Metoprolol lowers resting heart rate, so a reading of 55 shows as expected instead of setting off an alarm.

Every target shows where it came from, and every status comes with a reason. Tap "Why Halden says this" to see the facts behind it.

Halden's type 2 diabetes screen. Control is close to target, based on an A1c of 7.1% against a target under 7%. Below, each target has its source, and blood pressure under 130/80 is marked as tighter because of diabetes and kidney disease.

Your health record comes with you.

Connect your record from health systems that use MyChart. You sign in on your health system's own page, and Halden never sees your password.

Your conditions, medicines, allergies, lab results and visits arrive in one place. New lab results show up with their trend. When a medicine changes, your charts mark the day, so you can see what happened before and after.

Halden's timeline. Conditions and medicines from the record run as bars across the year, with labs and events marked. A card notes that metoprolol was started on Oct 3 and resting heart rate dropped as expected.

Walk into every appointment ready.

Visit prep puts the last few months on one screen: what changed in your labs and readings, new medicines, and how you've felt. It takes about a minute to read.

  • Add your own questions before you go, then tick them off in the room.
  • Visit mode keeps your questions and notes in front of you during the exam.
  • Share a summary with your care team through a link that expires.
Halden's visit prep for Dr. Patel. In one minute: A1c came down to 7.1%, home blood pressure averaged 134/84, and metoprolol was added on Oct 3. A list shows what changed since the last visit.

For the people who help.

Maybe you drive your dad to his appointments, or you're the one your mom calls about her numbers. Halden lets her invite you to see what she picks, and nothing else.

She can pause or end sharing at any time. Her notes and questions stay hers. If a reading needs a look, you'll hear about it.

Questions

Is Halden a medical device?

No. Halden is a wellness app. It shows your own data over time and explains it in plain words. It doesn't diagnose anything or tell you to change a medicine. Your care team makes those calls.

Do I need an Apple Watch?

No. Halden works with whatever is in Apple Health: a blood pressure cuff, a glucose meter, a scale, or readings you type in. An Apple Watch adds heart rate, sleep and activity.

Which health systems can I connect?

Health systems in the US that use MyChart. You pick your state, then your health system, then sign in on its own page.

Is there an Android version?

Not yet. Halden is built for iPhone and Apple Watch first. A summary you share with a link opens in any browser, on any phone.

Can I delete my data?

Yes. Delete your account in Settings and your data is removed from our servers right away.

Coming soon to the App Store.
