Your labs, your symptoms and every dose on one chart. And two pages your doctor can read in sixty seconds.

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.

ONE TIMELINE, NOT THREE

Your thyroid 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.

Patterns you can point at, in your own data, instead of a feeling you cannot put
into words.

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, with a
link to what each test measures.
• How you feel, in about thirty seconds, 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, taken from your own data.
• The trends behind them, with the chart for each.
• Black on white, with every status stated in words rather than colour, so
nothing is lost to a photocopier or to a reader who does not see red and green
apart.

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 does not provide medical advice. Always seek the advice of your doctor or another qualified health professional in addition to using this app, and before making any medical decision.

Haloscan is not a clinic and does not replace your doctor. There are no
consultations to buy and no courses. It does not diagnose, it does not treat,
and it does not tell you what your results mean or why you feel how you feel. It
shows you your own data clearly, so you can ask better questions of the person who does.

It is not a medical device, and it is not a substitute for one.

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. Free, with or without a subscription, and still yours if you cancel. Your
medical history is not a hostage.

Delete your account and everything in it from Settings, in two taps, at any
time.

WHO IT IS FOR

People with Hashimoto's thyroiditis, hypothyroidism, an underactive thyroid, a
thyroidectomy or Graves' disease after treatment. Anyone taking thyroid hormone replacement and keeping an eye on how a dose is working. Anyone who has been handed a lab printout and a five-minute appointment and asked to make sense of both.

SUBSCRIPTION

Free to try for 14 days. After that, an annual or weekly subscription keeps your
history and your doctor reports. Cancel any time in Google Play, under
Subscriptions.
