What you can track

Everything your doctor actually wants to know.

No clutter. Just the daily data points that matter for managing POTS — logged in under a minute.

💧

Fluid Intake

Track your water intake to get you closer to your daily goal.

🧂

Sodium Intake

Set your own sources — LMNT, Liquid IV, salt capsules, fast chews — with custom dosages so the math is always done for you.

🌀

Symptoms & Severity

Log dizziness, fatigue, brain fog, palpitations, and more with a simple severity scale. Fully customized to your personal symptoms.

⚡

Energy Levels

A quick daily energy rating to start seeing patterns across your good days and harder ones.

📝

Daily Notes

Add the context numbers can't capture — things you want to remember and what you want your doctor to knows.

🎯

Personal Goals

Set your daily fluid and sodium targets. Your goals, your body — not a generic recommendation.

Built around you

Because your chronic illness doesn't always look like everyone else's.

Most trackers give you a rigid set of fields. A Little Tachy lets you define your own — your sodium sources, your symptom list, your intake goals.

Set the sodium amount for each source type once and never have to calculate it again. Add one source and multiple amounts once. No more doing the math in your head every time you mix up an LMNT.

Customize your symptom list, and you can use it for any chronic illness — not just POTS.

The backstory

Made by someone who gets it.

A Little Tachy wasn't built by a wellness startup. It was built by someone who has POTS, got tired of notes apps and expensive non-customizable apps, and wanted something that was simple and looked good.

You have enough going on - an email is the only information you need to create your account. That's it. You can start tracking immediately and customize along the way.
