A thyroid tracker that keeps everything on your phone.

Thyrowise logs your TSH, your levothyroxine doses and the symptoms that drift in between — with no account, no login and no server to leak. It is free on iPhone and Apple Watch.

What it does

Living with hypothyroidism or Hashimoto's thyroiditis is a small pill every morning, labs every few months, and symptoms that move slowly enough to be hard to remember by the next appointment. Thyrowise holds those three things in one place.

Labs. Log TSH, free T4, free T3, total T4, total T3, TPO antibodies and thyroglobulin antibodies, with the date each was drawn.
Medication. A daily levothyroxine reminder that, once you mark the dose taken, counts down the empty-stomach wait and then tells you coffee and breakfast are fine.
Dose changes. Record what your doctor changed and when, so the next lab result has something to be read against.
Symptoms. One-tap chips for fatigue, brain fog, hair loss, cold intolerance and the rest.
Nodules and scans. Store what the ultrasound report said, including its TI-RADS category, and follow a nodule’s measurements over time.

The part people notice first

Levothyroxine is absorbed best on an empty stomach, so most people take it first thing and wait 30 to 60 minutes before coffee or breakfast. Thyrowise runs that wait as a live countdown on the Lock Screen and on the Apple Watch, so you are not guessing whether enough time has passed.

No account, and nothing to leak

Thyrowise has no sign-up, no login and no server. Every lab value, dose and symptom is written to your own device and stays there. There is no analytics SDK and no advertising SDK in the app, so there is no profile of your thyroid disease sitting anywhere to be breached, sold, or lost when a company shuts down.

The practical consequence: nobody can lock you out of your own history, and export is a plain PDF or CSV you own.

What the phone already knows

Weight, sleep and resting heart rate are three of the things people with an under- or over-treated thyroid actually watch, and an iPhone or Apple Watch is already measuring them. If you turn it on, Thyrowise reads those from Apple Health and shows them beside your log, so the picture is not limited to what you remembered to tap.

Nothing is inferred or diagnosed from them. The read is optional, off until you enable it, and can be revoked in Health at any time.

Every medical statement in the app is sourced

Thyrowise does not generate advice. Where it states a number — a typical reference range, a retest interval, an absorption rule — it names the published source, and a Sources screen in the app lists all of them. Those sources are the American Thyroid Association, NIDDK at the National Institutes of Health, MedlinePlus at the U.S. National Library of Medicine, and the American College of Radiology for TI-RADS.

Insights in the app are counts of your own logs, stated as counts. There is no score, no risk model and no black-box AI making a guess about your thyroid.
