When you are back, one question waits: what did they say?
Your own record, restated. Educational, not medical advice.
Have a ring or a watch?
Connect Oura, WHOOP, and Apple Health. Osmi will connect your sleep, heart rate, and exercise to complete your full thyroid picture. Don’t have a wearable? No problem, it’s optional.
What you eat and put on your skin matters.
Scan any product and get an instant read: what the label lists, what we’d skip, and a better swap in the same aisle. Grocery store or your own pantry, it works the same. We built the scanner so choosing products you feel good about is easy.
- Food and drinks: added sugars, seed oils, hidden gluten
- Skincare and makeup: fragrance and other ingredients we flag
- A better swap, right next to what you scanned

You keep saying it. Nobody writes it down.
- Tired no matter how much I sleep.
- I lose the word in the middle of the sentence.
- I’m cold when everyone else is fine.
Up to 60%of thyroid issues go undiagnosed.
You’re not imagining it, and you haven’t failed at fixing it. The story was just never written down in one place. That is what Osmi is for.
From women managing a thyroid condition
“Three doctors said my labs were fine. Now when I say I’m not, I have something to show them.”
Rachel, 44
“I scan everything now. Half my pantry surprised me, and not in a good way.”
“I have Hashimoto’s and about five apps that each track one thing. This replaced all of them, which my brain appreciates.”
“It’s the first app I’ve kept past a week. That says a lot for me.”
“I love Osmi, and so does my doctor. I took my summary page to my last appointment and had the most productive session in a long time.”
“My labs live in three different portals. Or lived. Everything’s in one spot now and I can actually find things.”
“I always felt like I was making it up. Seeing six months written down, I wasn’t.”

What is Osmi?
Osmi is a health-tracking app for women managing a thyroid condition. It keeps your labs, symptoms, cycle, and sleep in one record, side by side, so you can see what tracks with what.
Who is Osmi for?
Women with Hashimoto’s or hypothyroidism, whether you’re diagnosed or still chasing answers. If you’ve ever been told your labs are normal while you still feel awful, Osmi was built for you. You don’t need to be technical, and you don’t need to log perfectly. Good enough counts.
How does Osmi work?
You check in once a day, and it takes about a minute. You answer 7 questions or speak with Rose, your thyroid mascot who lives in the app. Your answers build your record: symptoms, labs, cycle, and sleep, side by side. The longer the record runs, the more useful it becomes at your next appointment.
What does the scanner do?
You scan a product and Osmi reads the ingredient list for you. Instead of a generic score, you get a plain answer about those ingredients through the lens of your thyroid condition, with the reasoning spelled out.
Can Osmi track my cycle and my thyroid symptoms together?
Yes. Your cycle sits next to your symptoms, sleep, and labs on one dated timeline, so you can see what lines up with what. That matters because thyroid symptoms and cycle changes often get tangled together, and a dated record of both is the clearest way to talk them through with your doctor.
How much does Osmi cost?
Download it on the App Store to see the current plans.
Is this another symptom journal?
No. A journal holds one kind of note. Osmi holds the whole picture: your blood tests against their printed ranges, your daily answers, your cycle, your sleep, and your product scans, together on one timeline. The parts finally explain each other.
My labs came back normal. Is Osmi still for me?
Osmi was built for exactly this moment. Normal on paper while you feel exhausted, foggy, and cold is the most common story we hear. Whether it’s Hashimoto’s, hypothyroidism, or a thyroid that simply feels off, Osmi starts from how you actually feel, and your daily read grows from there.
Will Osmi diagnose what’s going on?
No. Osmi never diagnoses, treats, or prescribes, and it will never ask you to change medication. It helps you see patterns in how you feel and what you scan, and gives you natural, daily things to try. Bring your patterns to your next appointment if you like. They make good evidence.
Do I need an Oura, a WHOOP, or an Apple Watch?
No. Osmi works from your check-ins and your scans on its own. If you do wear one, syncing it makes your daily read sharper, because sleep and temperature tell Osmi things you shouldn’t have to type.
How is this different from Yuka or a clean-eating app?
Those apps grade the product and give everyone the same number. Osmi reads the product against you: your symptoms, your scan history, your cycle, your sleep. The answer changes because your body does.
When does Osmi launch?
It's live now. Download it on the App Store.
Is my data private?
Yes. Your scans, cycle, and wearable data exist to build your reads, nothing else. Never sold, never used for ads, and you can export or delete everything whenever you want.
