Plain answer

What this page is about

This page is for choosing between app types, not for learning how to track POTS. For POTS, the app matters less than whether you can keep using it on low-energy days and bring a clear history to the clinician who asks what changed.

Why it matters

What to look for in a POTS tracker

  • Orthostatic vitals should stay connected to symptoms and daily context.
  • Salt, water, medications, heat, illness, and flare notes should be easy to add.
  • The app should help with appointment prep, not only daily tracking.

Comparison table

How the options compare

Use this as a fit check, not a winner-takes-all verdict. The right tracker is the one you can keep using when symptoms are already taking up the day.

Factor Generic tracker Zebra
POTS context Often requires custom setup POTS-aware from the start
Orthostatic vitals May be separate or missing Built into the tracking flow
Salt and water May need workarounds Tracked beside symptoms
Appointment prep Often requires manual summary Doctor-ready report workflow
