Low-effort tracking

Track symptoms automatically

Voice or text check-ins turn inflammatory back pain (location, intensity), morning stiffness duration (minutes), fatigue into a structured timeline, so you do less manual logging on already hard days.

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 AS symptoms?

The best way to track Ankylosing Spondylitis 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 can review.

Appointment questions

What should your AS symptom tracker record?

A strong Ankylosing Spondylitis tracker records separate symptom domains, timing, triggers, treatment context, and functional impact. For Ankylosing Spondylitis, the most useful entries are inflammatory back pain (location, intensity), morning stiffness duration (minutes), fatigue, peripheral joint involvement, eye symptoms (uveitis flares).

How does tracking Ankylosing Spondylitis help at appointments?

Tracking gives your rheumatologist 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 Ankylosing Spondylitis 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?

Inflammatory back pain (location, intensity)
Morning stiffness duration (minutes)
Fatigue
Peripheral joint involvement
Eye symptoms (uveitis flares)
Activity tolerance
Biologic / DMARD adherence and side effects
Sleep quality (waking from pain)

What patterns matter?

Morning stiffness duration shifting up or down across weeks
Activity-induced relief vs rest-induced stiffness
Flare clusters in the months before a biologic switch
Uveitis episodes alongside spinal pain spikes

What should you bring?

Morning stiffness duration trend with daily values
Pain map across spine, SI joints, and peripheral joints
Biologic / DMARD adherence and side-effect log
Functional impact on work, sleep, and exercise
Specific questions for your rheumatologist

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.

Need	Generic tracker	Juno
Inflammatory pain pattern	One pain score, no posture or rest context	Pain logged with rest vs activity context, the AS-defining axis
Morning stiffness clock	Yes/no checkbox	Duration in minutes — a clinical disease-activity signal
Biologic response	A list of medications	Doses logged with timing, side effects, and disease-activity trend
Multi-system flares	Spine only	Spine, eye, gut, and skin tracked together
Rheumatology prep	Recall in the appointment	Page summary timed to the visit

Key benefits

Four ways Juno makes life with AS a little easier.

Spot Ankylosing Spondylitis flare patterns sooner

Track shifts in inflammatory back pain (location, intensity), morning stiffness duration (minutes), fatigue, peripheral joint involvement before they blur together by the next appointment.

Track symptoms automatically

Tell Juno what happened in plain language and it turns that into a clear symptom timeline without extra admin.

FAQs

A few common questions.

What is ankylosing spondylitis?

Ankylosing spondylitis is a chronic inflammatory arthritis that primarily affects the spine and sacroiliac joints, often causing inflammatory back pain (worse at rest, better with movement) and prolonged morning stiffness. It is part of the broader axial spondyloarthritis spectrum.

Why track morning stiffness duration?

Stiffness duration is one of the more reliable day-to-day disease-activity signals in axial spondyloarthritis. Consistent tracking gives a far better picture than a single recall at a six-month appointment.

Can Juno track biologic response?

Yes — doses are logged with timing, side effects, and tracked alongside symptom data so the response (and any waning effect before the next dose) is visible.

Should I tell Juno about eye or gut symptoms?

If they're relevant. AS frequently overlaps with uveitis and IBD; logging them in the same place keeps the picture coherent for your rheumatologist.

Is my data private?

Yes. Health data is not sold and you control what is shared.
