Haloscan

Haloscan is a thyroid tracker for people managing Hashimoto's thyroiditis and hypothyroidism who have been told their results are "normal" while they still feel awful.

Your lab results, your daily symptoms and every levothyroxine dose change sit on a single chart. Pick any symptom and any marker and see how they line up: energy against TSH, brain fog against free T3, how you felt in the weeks after a dose change.

WHAT YOU TRACK

• TSH, free T4, free T3, reverse T3, TPO and thyroglobulin antibodies, and the rest of a full thyroid panel.
• Every result against the reference range your own laboratory printed.
• How you feel, morning and evening: energy, brain fog, mood, temperature, sleep, weight, heart rate.
• Every levothyroxine or liothyronine dose and every change, with reminders at your times.
• Appointments, and the notes you want to remember afterwards.
• A flag before a blood draw if you take biotin, which can interfere with thyroid blood tests.

THE DOCTOR REPORT

Two pages built from your own results, for an appointment that is twelve minutes long: the questions worth asking, the trends behind them, and a chart for each. Black on white, with every status stated in words rather than colour. Print it or send it ahead.

PHOTOGRAPH THE PAPER

Point your camera at a lab report and the values are read off it. You check them before anything is saved. The photograph itself is never stored.

WHAT IT IS NOT

Haloscan is not a clinic and does not replace your doctor. It does not diagnose, it does not treat, and it does not tell you what your results mean. It shows you your own data clearly, so you can ask better questions of the person who does. It is not a medical device.

YOUR RECORD IS YOURS

Never sold, never shared with insurers or employers, never used to train AI. Export every lab, every dose and every symptom to a spreadsheet whenever you like, with or without a subscription. Delete your account and everything in it from Settings, at any time.
