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 Postural Orthostatic Tachycardia Syndrome symptoms?

The best way to track POTS 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 cardiologist or autonomic specialist can review.

Appointment questions

What should your Postural Orthostatic Tachycardia Syndrome symptom tracker record?

A strong POTS tracker records separate symptom domains, timing, triggers, treatment context, and functional impact. For POTS, the most useful entries are dizziness and pre-syncope episodes, resting and standing heart rate notes, hydration intake, sodium intake, compression wear adherence.

How does tracking POTS help at appointments?

Tracking gives your cardiologist or autonomic 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 POTS 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?

Dizziness and pre-syncope episodes
Resting and standing heart rate notes
Hydration intake
Sodium intake
Compression wear adherence
Heat exposure
Standing tolerance (minutes)
Brain fog and exercise intolerance

What patterns matter?

Hydration and sodium against same-day symptom severity
Heat-wave days and standing tolerance
Sleep loss preceding worse-symptom mornings
Compression wear adherence vs pre-syncope episodes

What should you bring?

Resting and standing heart rate notes from home monitoring
Symptom log organised by posture (lying, sitting, standing, walking)
Hydration, salt, and compression adherence
Medication and supplement notes (with timing)
Specific questions for your cardiologist or autonomic 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
Posture-aware symptoms	One symptom log, no posture context	Symptoms tagged by lying / sitting / standing / walking
Heart rate notes	Just an average step counter	Standing-vs-resting deltas you can show your cardiologist
Salt + hydration	Generic water reminders	Adherence tied to symptom severity, day by day
Heat tracking	Not tracked at all	Heat days flagged against same-day symptoms
Pre-syncope log	Buried in free-text notes	Episodes captured with the context that preceded them

FAQs

A few common questions.

What is POTS?

POTS is a form of dysautonomia diagnosed when standing causes a sustained heart rate increase (commonly ≥30 bpm in adults, ≥40 bpm in adolescents) without a significant drop in blood pressure, alongside orthostatic symptoms such as dizziness, brain fog, and fatigue.

Should I tag every dizzy moment?

You don't have to. Even a few tagged episodes per week — with what you were doing, hydration, and recent sleep — give a clearer picture than a flood of partial entries.

Does Juno read my smartwatch heart rate?

Yes. Juno connects to 20+ wearables and health platforms, including Apple Health, Fitbit, Oura and Garmin, so heart-rate and sleep data sit next to your symptom notes. You can also just tell Juno a reading, and it works without a wearable too.

Can it tell my cardiologist if it's POTS?

No. Diagnosis is your specialist's call (often via a tilt-table test or active stand test). Juno helps you walk in with a tidy log of what your body is actually doing.

How does it help on heat-wave days?

Heat is a known POTS trigger. Tagging heat exposure surfaces whether your worst weeks line up with hot days — and helps your team plan around it.

What is the best app for tracking POTS?

It depends on what you need to record: Visible and TachyMon focus on heart rate, while Juno lets you describe dizzy spells by voice or text and turns them into a summary for your doctor. We compare six apps, including where another app is the better fit, in our guide to the best apps for POTS.
