Understand your condition — don't just record it. Your condition doesn't fit in a box, and your tracker shouldn't either. TrackDX is the symptom tracker built to handle whatever you're living with — migraines, sciatica, IBS, eczema, food allergies, hypoglycemia, or something entirely your own. Log episodes, triggers, and medications in seconds, and let TrackDX surface the patterns you'd never spot on your own. BUILT FOR ANY CONDITION — NOT JUST ONE Most apps pick a single condition and stop there. TrackDX lets you track as many conditions as you need, each with its own triggers and medications, all in one place. FOUR THINGS THAT EXPLAIN ALMOST EVERYTHING • Episodes — log the date, start time, duration, intensity (1–10), any relief medications you took, how well each one worked, a quick note, and your suspected cause, in well under a minute. • Triggers — log them any day, even when nothing happens. That "negative data" is what turns a hunch into a real hit‑rate. • Preventative medications — record every medication and every period you were on it, so TrackDX can tell you whether it's actually changing your episode frequency or severity. • Relief medications — record what you took and rate how much it helped from 0 to 10, so you know what to reach for next time. INSIGHTS THAT GO BEYOND A LOGBOOK Anyone can keep a diary. TrackDX turns yours into statistics: episode frequency over time, which preventative medications are helping the most, which triggers are the most impactful, and how well each relief medication works — using advanced statistical models that adjust for the other factors to give you the true picture. A ONE‑PAGE SUMMARY FOR YOUR DOCTOR Export a clean physician summary — episode frequency, severity trends, trigger odds ratios, and medication efficacy, all statistically adjusted — so appointments start with data instead of "I'm not sure if my meds are helping." MOVING FROM ANOTHER APP? Bring your history with you. TrackDX walks you through converting your old tracker's data with an AI assistant, then checks the file and shows you exactly what will import before anything is saved — so you don't start from zero. YOUR DATA STAYS YOURS Everything you log in TrackDX is stored only on your device. Nothing is uploaded to a server, sold, or shared with third parties. Data leaves your device only when you choose to export it yourself — as a spreadsheet you control, or a physician summary you decide to share. Delete the app, and your data is gone. — TrackDX is a personal tracking tool, not a medical device. The insights are statistics based on what you log — they are not medical advice, a diagnosis, or a treatment recommendation. Always consult a qualified healthcare professional about your condition and before starting, stopping, or changing any medication. If you are experiencing a medical emergency, call your local emergency number.
