Recognize the problem
What the month feels like
By the time the appointment starts, the story is split across Notes, screenshots, half-finished trackers, and memory.
That is why real symptom history still turns into guesswork, especially when brain fog makes recall harder or the worst flare is already over.
"I have pieces of it everywhere."
"I knew it mattered, but I forgot by the appointment."
"Nothing showed the full picture when I needed it."
What changes with Zebra
Zebra is not just a place to track. It is the bridge between a hard month and a clearer appointment, especially when symptoms overlap and memory gets unreliable.
One body, one timeline
POTS notes in one app, pain somewhere else, medication changes in memory, and screenshots buried in Photos.
Flares, orthostatic vitals, meds, salt, water, triggers, notes, and overlap symptoms stay connected in one record.
Proof under pressure
You try to summarize weeks of symptoms while tired, foggy, rushed, or worried about being dismissed again.
Zebra gives you a recent timeline and doctor-ready PDF so the important parts are easier to review and share.
Bad-day friendly
The days that matter most are often the days with the least energy to type, sort, and explain.
A quick flare-day check-in can stand on its own, without streaks, guilt, or a demand to catch up perfectly.
Zebra organizes patient-entered history for care conversations. It does not diagnose, treat, or promise what a clinician will conclude.
What Zebra tracks
Zebra keeps the daily record short, structured, and useful later. On a hard day, track only what matters and leave.
Track severity, duration, and what changed so a bad day does not have to be reconstructed from memory later.
Keep dizziness, pain, fatigue, brain fog, palpitations, notes, and overlap symptoms in one dated history.
Record timing and notes so medication changes are easier to discuss with a clinician.
Track hydration and salt beside symptoms, while leaving medical decisions about salt and fluids to your care team.
Save lying, sitting, and standing observations with the symptoms and context from the same day.
Capture possible triggers, activity, stress, infection, heat, or notes when they matter, and skip them when you are tired.
Turn recent tracking into a clearer appointment summary instead of handing over a pile of disconnected notes.
Zebra is for tracking and appointment preparation. It does not diagnose, treat, or replace medical care.
Built around real invisible illness needs
The page stays product-led, but the tracking structure is grounded in common needs described by trusted medical and patient-education sources.
POTS and dysautonomia
POTS can involve dizziness, fatigue, brain fog, palpitations, and symptoms that worsen when upright. Zebra keeps orthostatic vitals beside daily symptoms instead of separating the numbers from the day.
EDS / HSD
EDS and hypermobility spectrum disorders can affect multiple body systems. Zebra gives pain, fatigue, notes, and overlap symptoms one calm place to land.
Fibromyalgia
Fibromyalgia commonly involves widespread pain, fatigue, sleep problems, and thinking or memory issues. Zebra helps keep flares, symptoms, medications, triggers, and notes reviewable before an appointment.
Long COVID and ME/CFS overlap
Long COVID and ME/CFS guidance highlights post-exertional symptom worsening and flare history. Zebra helps preserve timing, possible triggers, and recovery notes without turning tracking into homework.
This section is educational context, not medical advice. Talk with a healthcare professional about diagnosis, treatment, medication, salt or fluid changes, and concerning symptoms.
Doctor-ready report
Zebra turns patient-entered symptom history into a doctor-ready PDF report you can review before a specialist appointment instead of reconstructing the month from memory.
Instead of retelling the month from memory, you can review a dated record of what happened, how often, and what changed.
The 30-day summary can include flares, symptoms, medications, salt, water, orthostatic vitals, triggers, notes, and appointment context so appointment prep depends less on perfect recall.
Report preview

Appointment prep
Zebra helps you turn the week before an appointment into a clearer story: what changed, what repeated, what affected daily life, and what you want to ask while you are in the room.
What to capture first
Track severity, duration, and what changed so the worst days do not disappear once the flare passes.
Choose the symptoms that matter most instead of trying to document every sensation perfectly.
Keep timing, dose notes, side effects, and questions beside the symptom timeline.
Track hydration and salt beside symptoms when they are relevant to your care plan.
Save lying, sitting, and standing observations with the same day’s symptoms and notes.
Capture what symptoms changed about standing, working, school, sleep, errands, or recovery.
Write the questions you do not want brain fog, stress, or a short appointment to erase.
How Zebra works
The flow stays short on bad days and gets more useful as the appointment gets closer.
Log symptoms, flares, orthostatic vitals, meds, salt, water, triggers, and notes in one quick check-in.
Keep orthostatic vitals and daily context in the same timeline so patterns are easier to review later.
Review what changed before the visit and export a doctor-ready report when you want something clean to bring into the room.
App preview
The page now leads with the report, but the whole product is still built around short check-ins that stay usable on bad days.
Built for flare days
Zebra is designed to stay usable when you are dizzy, exhausted, foggy, or in pain.
Open Zebra, tap what changed, and leave. No blank setup. No wellness homework. No streaks. The goal is a usable record, not more time in the app.
What happens in under a minute
Why it feels lighter
You do not have to invent the structure first.
Why it matters later
That is what makes the doctor report possible.
One calm place for the daily record.
Orthostatic test
In the same record as everything else, not in a separate tool you have to reconcile later.
Zebra keeps lying, sitting, and standing vitals connected to your symptoms instead of splitting them into another tool.
The guided sequence
Why that helps
Doctors can see them beside the rest of the day.
Why it matters
You are not bouncing between multiple health tools.
Vitals stay useful because they stay connected.
Trends and patterns
Your history becomes easier to read before you have to explain it under pressure.
Over time, scattered bad days become a pattern you can review and turn into a stronger appointment summary.
What changes over time
The shift
The app helps you keep the thread between appointments.
The payoff
You can review what happened before the room gets overwhelming.
The clearer the history, the better the report.
Medication, hydration, salt, triggers, and notes
Symptoms make more sense when the surrounding context is still attached to the same day.
Zebra keeps medications, hydration, salt, triggers, and notes beside symptoms so flares are easier to review later and appointment prep takes less reconstructing.
The context that stays attached
Why it matters
The details that help explain a flare stay connected instead of scattered across multiple apps.
Why it converts to a report
That makes the doctor-ready report more useful when you need to summarize quickly.
Useful context beats a blank document every time.
Who Zebra is for
Yes, if the hard part is not tracking once. The hard part is remembering, explaining, and organizing it later.
Zebra is for people who need a clearer record, not a generic wellness dashboard.
Trust, safety, and privacy
Zebra stays focused on organizing patient-entered history for care conversations and specialist appointments. It does not diagnose, treat, prevent, or replace medical care.
Trust at a glance
Zebra is designed to help you keep a clearer record for specialist appointments, especially when symptoms overlap and recall is unreliable. The app and knowledge hub support self-organization and care conversations, not diagnosis, treatment, prevention, or health-data selling.
The end state
More prepared. Less overwhelmed.The goal is not to make illness feel tidy. It is to help the appointment feel calmer because your record is already there.
App health data is stored on your iPhone and may sync through your personal iCloud account, depending on Apple/iCloud settings and the current app build. Zebra does not require a Zebra account or run a separate Zebra health-data server.
Zebra fits best when you need a clearer symptom history before cardiology, specialist, or follow-up appointments.
No account required, no health-data server, and no rebuilding your history in someone else’s system.
Short flows, clear hierarchy, and low-energy use for flare days.
Built around appointments, not self-optimization or wellness streaks.
No diagnosis, no treatment advice, no prevention claims, and no overclaiming about what your data means.
Zebra is not an emergency tool, symptom checker, or replacement for urgent or professional medical care.
What Zebra summarizes comes from the history you track and review yourself.

Open pageWhy Zebra is different
Most tracker apps make you build your own system or frame the body like a wellness project. Zebra is built for the harder job: tracking POTS, EDS, Fibromyalgia, dysautonomia, and overlapping symptoms when you are already tired.
Zebra is an iPhone symptom tracker for invisible illness. It keeps symptoms, flares, orthostatic vitals, medications, salt, water, triggers, notes, and appointment context in one record so you can create proof for appointments. The goal is not diagnosis. The goal is less memory work and a clearer doctor report.
Structure
Notes and spreadsheets start blank, so you have to invent the system while you are already tired and trying to remember what matters.
Zebra gives symptom tracking structure from the start: flares, symptoms, triggers, meds, salt, water, orthostatic vitals, and notes.
Orthostatic tracking
Generic trackers often separate vitals from symptoms, which makes POTS and dysautonomia history harder to review later.
Zebra keeps lying, sitting, and standing orthostatic vitals beside the symptom timeline and daily context.
Appointment prep
A month of notes can still turn into a rushed explanation when the doctor asks what changed, how often it happened, and what seemed related.
Zebra turns patient-entered history into a doctor-ready symptom report for specialist and cardiology appointments.
Privacy
Many health tools require an account, sync through a service, or feel broader than the problem you need solved.
Zebra is private by design and keeps the focus on your own record for care conversations.
Flare days
Wellness and habit apps can make tracking feel like another task you failed to complete.
Zebra is designed for dizzy, exhausted, foggy, or painful days where one quick check-in is enough.
Condition-specific tracking
Zebra is most useful when symptoms overlap, change by position or activity, and become hard to summarize from memory before an appointment.
Track upright symptoms, heart-rate context, hydration, salt, flares, and orthostatic test notes before a cardiology or specialist visit.
Keep autonomic symptoms, position changes, triggers, medications, and notes in one timeline instead of scattered notes.
Record pain, fatigue, overlap symptoms, and notes so variability is easier to explain later.
Track pain, fatigue, brain fog, flares, medication context, and the day-to-day impact that can be hard to reconstruct.
Capture fatigue, dizziness, brain fog, orthostatic symptoms, activity changes, and patterns between follow-up appointments.
Use lower-effort check-ins to preserve history around fatigue, post-exertional worsening, and recovery notes.
