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.

Game changer

It feels like having someone who understands chronic illness with me all the time. Juno logs symptoms, remembers what helped before, and keeps cheering me on.

Really great app

I can talk naturally while Juno quietly logs symptoms, mood, pain, and what I need to raise with my doctor. Tracking everything finally feels easy.

Complex illness support

This is the first app that has been able to juggle all of my chronic illnesses. It helps with symptom logging, spotting correlations, and preparing for appointments.

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.

Less alone

I have Multiple Sclerosis, and Juno has genuinely changed how I manage my days. It helps me pace my energy, track symptoms, and feel heard when I'm struggling.

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.

Quick answer

What is the best way to track Rheumatoid arthritis symptoms?

The best way to track Arthritis is to separate symptoms by domain, log what changed when it happened, and connect each entry to triggers, treatment, and daily impact. Juno turns low-effort voice or text check-ins into a timeline your rheumatologist or GP can review.

What should your Rheumatoid arthritis symptom tracker record?

A strong Arthritis tracker records separate symptom domains, timing, triggers, treatment context, and functional impact. For Arthritis, the most useful entries are joint pain by location, morning stiffness duration, joint swelling, mobility and range of motion, activity load.

How does tracking Arthritis help at appointments?

Tracking gives your rheumatologist or GP a cleaner timeline than memory can provide. It turns scattered day-to-day notes into onset, duration, recovery, possible triggers, medication context, and the questions you need answered.

When should new Arthritis symptoms be escalated?

New, sudden, severe, or worsening symptoms should be shared with your clinical team promptly, especially when they affect daily safety, function, medication response, or a body system your care team is already monitoring. Juno helps you record what changed, but your clinician decides what needs urgent care.

What should you log?

  • Joint pain by location
  • Morning stiffness duration
  • Joint swelling
  • Mobility and range of motion
  • Activity load
  • Medication doses and side effects
  • Sleep
  • Weather

What patterns matter?

  • Weather changes and joint pain or stiffness
  • Activity load and next-day stiffness
  • Medication response over time
  • Flare clusters across symmetric joints

What should you bring?

  • A joint-by-joint summary since your last visit
  • Morning stiffness duration and pattern
  • Medication adherence, side effects, and tapering notes
  • Functional impact (walking, stairs, work, sleep)
  • Specific questions for your rheumatologist or GP

Tracker comparison

What makes Juno different from a generic tracker?

Generic trackers often flatten complex symptoms into one daily score. Juno keeps the details separate enough for pattern recognition and clear enough for appointments.

FAQs

A few common questions.

What should I track for arthritis?

Which joints hurt and how much, how long morning stiffness lasts, any swelling, what you could and could not do, and your medication with any side effects. A short pain diary like this helps your rheumatologist see change between appointments.

Does it matter which type of arthritis I have?

It changes what you'd track most. Inflammatory types (e.g. rheumatoid, psoriatic) often benefit from tracking morning stiffness duration and symmetric flares; osteoarthritis tends to centre activity-related joint pain. Juno supports both.

Why track morning stiffness duration?

It's a meaningful clinical signal, especially for inflammatory arthritis. Tracking it across weeks gives a more reliable picture than recalling at the appointment.

Can I track arthritis medication too?

Yes. Log doses, missed doses, side effects and whether things feel better, so you and your rheumatologist can judge a treatment over weeks rather than from memory.

Can I compare my joints over time?

Yes. Each joint is its own track, so you can compare a knee or wrist month by month.

Does Juno change my medication?

No. Juno doesn't recommend, schedule, or change medications. That's between you and your rheumatologist or GP.

Is my data sold?

No. Health data isn't sold, and you control what's shared with anyone.
