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 Post-COVID-19 condition symptoms?

The best way to track Long COVID 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 post-COVID clinic, GP, or specialist can review.

Appointment questions

What should your Post-COVID-19 condition symptom tracker record?

A strong Long COVID tracker records separate symptom domains, timing, triggers, treatment context, and functional impact. For Long COVID, the most useful entries are fatigue, brain fog and cognition, breathlessness and chest tightness, sleep continuity, post-exertional malaise (pem).

How does tracking Long COVID help at appointments?

Tracking gives your post-COVID clinic, GP, or specialist 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 Long COVID 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?

Fatigue
Brain fog and cognition
Breathlessness and chest tightness
Sleep continuity
Post-exertional malaise (PEM)
Activity load
Heart rate notes (resting, on standing)
Flares

What patterns matter?

Activity in the 24–72 hours before PEM episodes
Sleep continuity and next-day cognition
Heart-rate or breathing changes on standing or exertion
Trigger stacks driving worse-symptom days

What should you bring?

Symptom-domain summary across fatigue, cognition, breathing, autonomic
PEM episode log with duration and recovery
Functional impact (work, exercise tolerance, daily living)
Medication, supplement, and rehab response
Specific questions for your post-COVID clinic, GP, or specialist

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
Multi-system view	Pick one symptom	Fatigue, cognition, breathing, dysautonomia in one view
PEM tracking	No concept of delayed crashes	24–72h delayed-trigger view
Standing heart rate	Not surfaced	Standing-vs-resting notes against same-day symptoms
Rehab response	Vague 'better/worse'	Activity tolerance change tracked across weeks
Post-COVID prep	Verbal recall	Multi-system summary timed to the appointment

FAQs

A few common questions.

What is long COVID?

Long COVID, or post-COVID-19 condition, refers to symptoms that develop during or after COVID-19 infection and persist for at least three months, are not explained by another diagnosis, and impact daily functioning.

How does it overlap with ME/CFS?

Many people with long COVID develop a clinical picture that meets ME/CFS criteria, including PEM. Tracking activity and recovery helps with both, and many of the same pacing principles apply.

Should I track standing heart rate?

If dysautonomia is part of your long COVID picture, yes — standing-vs-resting notes are useful evidence.

Will it handle exercise rehab gracefully?

It tracks tolerance over time so you can see whether tolerance is moving in either direction. It does not prescribe a rehab plan — your clinical team does.

Is the data private?

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

What is the best app for tracking long COVID?

For heart-rate pacing with a wearable, Visible is the specialist choice, while Juno lets you log symptoms such as brain fog and breathlessness by voice or text and bring a summary to appointments. We compare them with Bearable and Guava in our guide to the best apps for ME/CFS and long COVID.
