Zebra

For invisible chronic illness

Flare tracker

Last reviewed: July 25, 2026

A flare tracker for bad days, brain fog, and appointment proof.

Zebra is an iPhone flare tracker that helps people quickly track severity, duration, symptoms, medications, triggers, and notes, then use that history for a doctor report.

Plain answer

What this page is about

A flare tracker only works if it is usable during the flare. Zebra keeps the check-in short so a dizzy, exhausted, foggy, or painful day can still be captured.

Later, those short check-ins become a clearer timeline for appointments.

Why it matters

Why flare tracking fails on hard days

  • Blank notes ask you to decide what matters while you are already low on energy.
  • Long forms create guilt when symptoms are worst.
  • Zebra lets one quick check-in be enough, then organizes the history for later.

Best fit

Choose Zebra if...

  • You want POTS, EDS/hEDS, Fibromyalgia, dysautonomia, and overlap symptoms in one iPhone app.
  • You are preparing for a doctor appointment and need a clearer history than memory or scattered notes.
  • You need low-energy flare tracking with symptoms, meds, salt, water, triggers, and orthostatic vitals together.

Not trying to be

Choose something else if...

  • You are looking for diagnosis, treatment advice, urgent care, or medication recommendations.
  • You primarily want fitness goals, habit streaks, workouts, or a generic wellness dashboard.
  • You need Android support today.

Trust and safety

Medically careful by design.

Zebra is not an emergency tool. Seek urgent care or emergency services for concerning, severe, or rapidly worsening symptoms.

Zebra does not diagnose, treat, prevent, cure, replace medical care, or interpret symptoms. Bring concerning symptoms, medication questions, salt/fluid changes, and treatment decisions to a qualified healthcare professional.

FAQ

Questions people ask before downloading Zebra.

Can I track only one thing on a bad day?

Yes. Zebra is designed so one quick check-in can still preserve the day without requiring a full diary.

Can flare history help with appointments?

Yes. Flare history can make it easier to review what changed, what repeated, and what questions you want to bring to a clinician.

Does Zebra diagnose POTS, EDS, Fibromyalgia, or dysautonomia?

No. Zebra does not diagnose, treat, prevent, or cure any condition. It helps you track patient-entered history so you can prepare for care conversations.

Can I use Zebra before I am diagnosed?

Yes. Zebra can help you track flares, symptoms, notes, and appointment questions before or after a diagnosis. It is not a substitute for professional medical care.

Is Zebra available on Android?

Not yet. Zebra is currently available for iPhone on the Apple App Store.

Is Zebra a fitness or wellness app?

No. Zebra is built for invisible illness tracking, brain fog, flare days, orthostatic vitals, and doctor report preparation. It is not a fitness app or streak-based wellness app.
