Chronic illness doesn’t stop between appointments. Juno keeps track of the weeks in between, so you don’t have to remember it all.

How it works

Juno is a personal health assistant for chronic illness. Here’s how it works.

  1. 1. Talk to Juno about your health
  2. 2. Juno tracks your symptoms for you
  3. 3. Juno finds patterns in your symptoms
  4. 4. Take a one-page summary to your doctor

1. Talk to Juno about your health

Chat with Juno by voice or text, like messaging someone who knows your health.

  • Tell Juno how you feel: “I’ve had a migraine since lunch”
  • Ask questions: “Is this new medicine making me tired?”
  • Prepare for appointments: “What should I ask my rheumatologist?”
  • Get support on hard days: “I’m exhausted and fed up today”

Juno remembers your condition, your medicines and what you’ve told it before, so you never start from scratch.

2. Juno tracks your symptoms for you

Without filling anything in.

  1. You talk to Juno by voice or text.
  2. Say something like “My headache is bad today.”
  3. Juno replies with support and guidance, and quietly logs the headache on the right day.
  4. Look back at your symptom history any time.

3. Juno finds patterns in your symptoms

After a few weeks, Juno points out what tends to happen together.

  • For example: headaches after nights with less than 6 hours’ sleep
  • These are clues to talk through with your doctor, not a diagnosis

4. Take a one-page summary to your doctor

Before an appointment, Juno turns the last few months into one page.

  • Your main symptoms and how often they happened
  • Any medicine changes
  • The questions you want to ask

Such an incredible help

I was recently diagnosed with MS, and Juno has been a lifesaver. It helps me track everything from sleep to pain and remember what to tell my doctor.

Anxiety killer

Facing a doctor and needing to be assertive is hard. Juno helps me put questions into words and think more clearly about pacing.

Genuinely helpful

It has actually helped me log things and understand the data myself. Sometimes Juno makes connections in my symptoms that I would have missed.

Amazing for pacing

I had been desperate for something to track symptoms, activities, medications, and mood. Juno gives me clearer data to bring into my doctor appointments.

Frequently asked questions

Who is Juno for?

Juno is for adults living with a long-term condition, from autoimmune conditions like lupus, rheumatoid arthritis and IBD, to chronic pain conditions like fibromyalgia and endometriosis, to complex and rare conditions like ME/CFS, POTS, Ehlers-Danlos and mast cell activation syndrome.

You don’t need a diagnosis. Many people use Juno while they work with their clinicians toward answers. Juno itself doesn’t diagnose conditions; only a qualified clinician can diagnose you.

What can I talk to Juno about?

Anything about living with your condition: a symptom that has changed, a medicine you are unsure about, a bad day, what to ask at the next appointment. Talk by voice or text, whichever feels easier. Juno remembers your history, so you never have to start from the beginning.

How does symptom tracking work?

You simply tell Juno how you feel, by text or voice. Say “I’ve had a pounding headache since lunch and I’m exhausted” and Juno logs the headache, the fatigue and the timing straight into your timeline. No forms.

She keeps it as part of your history and looks at it next to sleep, activity, medicines, weather and pollen. When something keeps happening, you can see what changed alongside it. That is a clue to take to your doctor, not a diagnosis.

What is in the doctor report?

A short summary of the period since your last visit: what changed, how often, what it stopped you doing, treatments and whether they helped, and the questions you want answered. It is built from what you have told Juno, so read it before you hand it over. You can email it or print a PDF to bring to your appointment.

How is Juno different from ChatGPT?

Juno is built for life with chronic illness. Insights from thousands of patients and input from hundreds of doctors shape how she asks questions and responds. She keeps your symptoms, treatments and day-to-day context together, helping you find relevant patterns and prepare for appointments.

How does Juno compare to other symptom tracker apps?

Most trackers ask you to fill in forms. With Juno you just say how you feel and she does the logging, then looks at it alongside sleep, activity, wearable data, weather and pollen. See how Juno compares.

Does Juno replace my doctor?

No. Juno works alongside your doctor, not instead of them: she helps you keep track between appointments and arrive prepared, so the time you have together goes to what matters.

Is my data secure, and how is it handled?

Yes. We never sell your health data. It is encrypted in transit and at rest, stored on secured servers in the United States, and protected by strict access controls. We use HIPAA security protocols as a benchmark. Our AI agreements prohibit using your health data to train models. See our Privacy Policy for details.

How much does Juno cost?

Juno has a free plan with symptom tracking, pacing, health insights, doctor reports, community access and limited AI chat. The optional paid plan adds unlimited AI chat and enhanced memory. Check the app for the current subscription price in your region.
