## What is Symptom Tracker?

Most symptom trackers ask three minutes a day and hand you a spreadsheet. Throughline asks ten seconds and hands you one page your doctor will actually read.

TEN SECONDS A DAY
One screen. Tap to log severity. No sliders, no typing, no forms. It saves as you go. If today is much like yesterday, fill the whole day in one tap and edit what changed.

THE APPOINTMENT BRIEF
Turn months of logs into a single page built for a ten-minute consultation: how many days you actually logged, what changed since your last visit, how often each symptom appeared and how bad it got, whether you took what you were prescribed, and the questions you wanted to ask. Export as a PDF and hand it over.

PATTERNS, WITH THE RECEIPTS
Throughline compares your symptoms against your medications and daily context, both same day and the day after. Every finding shows how many days it rests on and both averages being compared. When there is not enough data to say something responsible, it says that instead of showing you a colour-coded grid.

NO STREAKS. NO GUILT.
There is no chain to break and no badge to lose. Missing days are part of being ill, not a failure of discipline. One optional reminder a day, at a time you choose.

YOUR DATA STAYS YOURS
No account. No cloud. Everything lives on your device. Logging, editing any past entry, backing up and restoring, and full CSV export are free forever, including if you cancel.

THROUGHLINE PRO
Unlocks the Appointment Brief PDF, pattern analysis, unlimited tracking and full history. Everything above stays free.

Built for migraine, ME/CFS, fibromyalgia, endometriosis, IBD, arthritis, long COVID, MS and POTS, and anything else that needs explaining to a doctor who has ten minutes.

Throughline is a personal record. It is not a medical device and does not diagnose, treat, or give medical advice.
