If you've typed "Hashimoto's app" into the App Store and scrolled through a wall of near-identical screenshots wondering which one will still matter in a month, this is for you.
The short answer: six tools are worth naming, and they do different jobs. This list is not neutral. Osmi published it, and we rank ourselves first, because we built Osmi for exactly the gap the other five leave open. Every fact about every other app comes from that app's own pages, fetched the day this was written. Judge for yourself.
The list at a glance: Osmi for the whole picture in one record, ThyForLife for an established thyroid tracker with lab history, Paloma for care and tracking in one membership, HashiTrack for the widest thyroid feature list on paper, MyTherapy for free medication reminders, Bearable for general chronic-illness tracking with real wearable sync.
1. Osmi: the whole picture, in one record
Best for: keeping your thyroid symptoms, labs, cycle, and sleep together in one dated record you can show your doctor.
Ours, and we say so. Osmi keeps your thyroid symptoms, labs, cycle, and sleep in one dated record, reads product labels through the lens of your condition, and turns the daily check-in into a short game you play with your thyroid mascot, Rose. It doesn't diagnose. It shows each number against the range your lab printed and what changed since last time, so you understand where your numbers sit, and so your next appointment starts from evidence.
Where we are the wrong call: If all you want is a medication reminder, MyTherapy does that for free and does it well. If what you're after is a doctor service rather than a record, Paloma is built for that. And if your condition list runs well past your thyroid, a general tracker like Bearable may fit better.
2. ThyForLife: the established thyroid tracker
Best for: a thyroid-specific tracker with lab history.
ThyForLife calls itself "the only all-in-one self-management tool and global community platform that provides support for every thyroid condition." The facts back the breadth: it tracks bloodwork across the thyroid panel (TSH, T4, free T4, T3, free T3, and antibodies), a long symptom list, medications with reminders, and weight, and it normalizes lab results across different reference ranges. It's free to download on both platforms, with paid yearly subscriptions listed.
Worth knowing before you commit: cycle tracking and wearable sync aren't advertised on its site or store listing. If your symptoms move with your cycle, that's a gap to weigh.
3. Paloma: an online clinic with an app attached
Best for: care and tracking in one place, as a membership.
Paloma Health describes itself as "the first online medical practice focused on hypothyroidism", and that's the right way to understand its app: it's the front door to their care service. Through it you can order at-home test kits, hold video visits, message the care team, and track symptoms and thyroid labs. Full features require a membership.
If what you want is a doctor service built around hypothyroidism, this is that. If what you want is a standalone tracker, the membership model is the thing to weigh. Cycle tracking and wearable sync aren't mentioned on its pages.
4. HashiTrack: the newer thyroid-specific option
Best for: the widest thyroid-specific feature list on paper of the apps here.
HashiTrack describes itself as "a smart companion for people living with Hashimoto's or hypothyroidism." Its listing covers symptom, energy, and mood tracking, importable thyroid labs, cycle and pregnancy tracking, medications, and food logging via photo. It's free with paid subscriptions. One transparency note: its App Store listing sits under the same seller name as Paloma's app.
5. MyTherapy: the medication specialist
Best for: free, dependable medication reminders.
MyTherapy isn't a thyroid app, and it doesn't pretend to be. It calls itself a "personal, digital health companion" for reliable medication reminders and consistent documentation. It tracks your meds, refills, symptoms, mood, and weight, and builds a report you can hand your doctor. It's completely free.
For levothyroxine's daily rhythm, a dependable reminder is no small thing. It doesn't advertise a thyroid lab panel or cycle tracking, and it won't give you a picture of how everything connects.
6. Bearable: the general tracker with real wearable sync
Best for: chronic-illness tracking across conditions, with wearables.
Bearable is a general chronic-illness tracker rather than a thyroid app, and a good one: symptoms, mood, sleep, cycle, and real wearable sync with Apple Health, Google Fit, and Fitbit. It doesn't advertise a thyroid lab panel, so your bloodwork lives elsewhere.
Who is missing, and why
Boost Thyroid used to come up in these lists. As of September 2026, its website now redirects to an unrelated domain and its US App Store listing returns no result, which is its own reminder: pick an app you can imagine still existing when your record is two years long.
What none of the other apps quite do
Read the list again and a pattern shows: the established thyroid trackers don't advertise cycle tracking, the one that does doesn't advertise wearable sync, and the apps with real wearable sync don't advertise thyroid labs. For a condition that lands overwhelmingly on women, whose symptoms tangle with cycles and sleep, the pieces live in different apps. That gap is the reason Osmi exists, and the reason it sits at number one on its own list.
Questions women ask about Hashimoto's apps
What is the best app for Hashimoto's?
Our answer is Osmi, and we're the publisher, so weigh that as you should. Among the others: ThyForLife for a thyroid-specific tracker with lab history, Paloma for care plus tracking as a membership, MyTherapy for free medication reminders. Each fact above comes from the apps' own pages.
Is there an app that tracks thyroid labs and my cycle together?
Among the apps above, HashiTrack lists both thyroid labs and cycle tracking. The established thyroid trackers don't advertise cycle features, and the strong cycle apps don't advertise thyroid labs. Bringing those together in one dated record is exactly what Osmi is built to do.
Do these apps replace seeing a doctor?
No, and the good ones don't claim to. A tracker's real job is making your appointments better: a dated record of symptoms, medications, and labs that your doctor can read in one look. Whatever you choose, pick the one you'll actually open every day.
Whichever app you land on, start the record today. Two weeks of dated entries beats two years of trying to remember.
