If your dose went up and you're now counting the weeks to the next blood test, trying to remember which pill you were on for which result, you're not disorganized. That's a lot to hold in your head.
Short answer: Yes, but usually in two halves. Apple Health's Medications feature, built into iPhone since iOS 16 in 2022, keeps your medication list, reminds you to log each dose as Taken or Skipped, and exports the list as a PDF. Reminder apps such as Medisafe and MyTherapy describe reminders, an intake log and reports for your doctor. Your thyroid results are the other half. Osmi's lab timeline shows each draw dated, against the range your own lab printed, with what you changed in between, like a dose change. Osmi's pages don't describe a pill reminder, and Osmi never suggests a dose.
Which app keeps which half of the record
Read from each product's own pages on November 11, 2026. A blank means the pages we read don't describe it, not that it can't be done.
| What you want kept | Apple Health Medications | Medisafe and MyTherapy | Osmi |
|---|---|---|---|
| A reminder when a dose is due | A notification, plus an optional follow-up if nothing is logged 30 minutes after the scheduled time | Both describe medication reminders | Not described on its pages |
| A log of each dose, taken or skipped | Taken or Skipped, with a history | MyTherapy documents every intake, taken or skipped | Not described on its pages |
| A medication list you can share | Export PDF, or share through Health Sharing | MyTherapy shares your medication plan and intake diary with your doctor | Not described on its pages |
| Something to hand your doctor | Export PDF of your current medications | Reports to share with your doctor | The appointment sheet: your line of results and what changed this chapter, shared in one tap |
| Lab results | A separate feature: Health Records downloads, or values you type in | Both log measurements. Lab ranges aren't described | Every result on its own card, against the range your own lab printed |
| Dose changes dated next to your draws | Not described | Not described | Each draw dated, with what you changed in between |
Why the dose change and the next draw belong on one line
Because that's how follow-up testing is set up. The American Thyroid Association puts it plainly: "Your doctor will check your blood 6 to 8 weeks after starting or changing your thyroid hormone dose." NIDDK gives the same 6 to 8 weeks after you begin the medicine, says each time your dose is adjusted you'll have another blood test, and says that once a dose is working, the test is probably repeated in 6 months and then once a year.
So a thyroid record moves in two speeds. Your labs come a few times a year. How you feel moves daily. A reminder app is built for the daily part: did the pill go in today. The follow-up draw asks a different question: what was going on in the weeks before this blood was taken?
That's where memory lets you down. Six weeks is long enough to forget the date a refill came in a different box, or the week you started iron. A dated line answers it without guessing.
What's worth writing down beside the pill
Not every detail. These are the ones the ATA and MedlinePlus name, plus the dose itself.
- The dose, and the day it changed. Osmi's own example reads "Dose up to 75 µg · 3 September", sitting on the same timeline as the draws before it. Write it the day it happens.
- The brand or maker on the refill. The ATA says the brands all contain the same levothyroxine but different inactive ingredients, and that "If a change in brand or manufacturer is unavoidable, you should make your physician aware of the change, so that your thyroid hormone levels can be rechecked." A 2022 study the ATA summarized found no significant difference in reaching a normal TSH between people whose generic changed maker and people whose didn't. The ATA still recommends a TSH check after a change of maker. Either way, the name on the label is worth keeping.
- Anything you started or stopped. The ATA's list of reasons to call your doctor includes starting or stopping a medicine that affects thyroid pills, and names antacids, calcium or iron supplements, biotin, estrogen (like in birth control) and seizure medicine. Our note on starting HRT while on thyroid medication covers the estrogen side in more depth.
- Biotin, with dates. The ATA says biotin, a common hair and nail supplement, "has no effect on thyroid hormone levels or thyroid function in the body", but can make thyroid blood tests read wrong. Its patient pages give different waits before a draw, anywhere from 2 days to 3 to 5 days. We won't pick one for you. Write down whether you take it, and ask your doctor or the lab before your next test.
- How you take it. The ATA says "the most important thing is to be consistent". If your routine shifted, a new breakfast time or a new pill alongside it, that's a dated change too.
- Which lab drew the blood. MedlinePlus says you can't compare results from different labs, and that trends read best from the same one. The lab's name belongs next to the number. Our guide to reference ranges explains why each lab prints its own.
None of this asks you to change anything. It's the context your doctor needs to read the next number.
Where Apple Health's Medications fits
If what you want is a nudge every morning, it's already on your iPhone. In the Health app you tap Browse, then Medications, add the medicine, choose its strength and set a schedule. Apple says you then get notifications reminding you to log it, and you tap Taken or Skipped. On Apple Watch the reminder offers Skipped, Taken, or Remind Me in 10 Minutes.
Three details worth knowing. If you stop a medicine, archiving it keeps its details and log history, while deleting it removes all of that. Drug interaction alerts are available only in the United States. And Apple says the Medications feature is not a substitute for professional medical judgment.
Apple Health can hold lab results too, through Health Records from supporting healthcare organizations or values you type in yourself. Apple's pages describe these as separate features. None of the pages we read shows a dose change sitting beside a lab result. If you keep your labs there already, our piece on Apple Health and thyroid labs covers what it does with them.
Where a reminder app fits
Medisafe describes tracking medications, appointments and measurements in one free app, a Medfriend who gets notified if you miss a dose, and progress reports to share with your doctor before every visit. MyTherapy describes medication reminders, a record of every intake, taken or skipped, and a way to share your medication plan and intake diary with your doctor.
Do reminders help? Two systematic reviews of trials, one in BMJ Open in 2020 and one in JMIR in 2025, found that medication apps may help people take medicines as prescribed. In both, most of the studies measured adherence by self-report, and none of the trials was about thyroid medicine. The honest answer is that reminders help with remembering, which is one job.
Where Osmi fits
Osmi is an iPhone app for women with Hashimoto's or hypothyroidism, and it keeps the other half. Every blood result sits on its own card, against the range your own lab printed. The timeline on Osmi's home page shows each draw dated, with what you changed in between: a dose change, a supplement, gluten out. The lab album page says blood gets drawn more often for a while after a dose changes, which is what NIDDK and the ATA tell patients to expect.
How you feel goes on the same record. The daily check-in takes about a minute, and your answers become dated entries beside your labs and your cycle.
Osmi doesn't diagnose. What it does is keep the line your doctor reads at the follow-up: each result against the range your own lab printed, with what changed in between. It will never suggest a dose or a supplement, and it will never ask you to change your medication. Its pages don't describe a pill reminder, so if you want the daily nudge, Apple Health or a reminder app does that job. For the wider picture, see what app shows your thyroid symptoms and your lab results together.
Taking it to the appointment
MedlinePlus says to write down all the medicines, vitamins and supplements you take, bring that list to your appointment, and share it there. Osmi's appointment sheet is one page with your line of results, what changed this chapter, your three questions and what's not on file yet, shared in one tap. Its example row reads "Iron since 4 August. Gluten out since 11 August. Dose unchanged."
The questions are yours to write. A few that come straight out of a dated record:
- "My dose changed on this date. When should my next blood test be?"
- "My refill came from a different maker on this date. Do you want to recheck my levels?"
- "I started iron on this date. Does that change anything about how I take my pill?"

Questions women ask about tracking thyroid medication
Is there an app that reminds me to take levothyroxine? Yes. Apple Health's Medications feature on iPhone sends a notification when a scheduled dose is due, and you can turn on a follow-up if it isn't logged 30 minutes later. Medisafe and MyTherapy describe medication reminders too. Osmi's pages don't describe a pill reminder.
Can Apple Health track my thyroid medication and my lab results? It holds both, as separate features. Medications keeps your list, schedule and Taken or Skipped log, and you can tap Export PDF to save or share a copy of your current medications. Health Records or manual entry holds lab values. Apple's pages don't describe a dose change shown beside a lab result.
How soon after a dose change is my thyroid blood test? The American Thyroid Association says your doctor will check your blood 6 to 8 weeks after starting or changing your thyroid hormone dose. NIDDK says each dose adjustment brings another blood test, and once a dose is working, the test is probably repeated in 6 months and then once a year. Your doctor sets your own timing.
Should I write down the brand of my thyroid medication? It's worth having. The ATA says different brands carry different inactive ingredients, and asks that your doctor knows about a change of brand or manufacturer so your levels can be rechecked. MedlinePlus says to learn the brand name and generic name of your medication.
Does Osmi tell me what dose to take? No. Osmi never suggests a dose or a supplement and will never ask you to change your medication. It shows each result against the range your own lab printed, with what changed in between, and the questions you bring to the appointment are yours.
Tonight, take a photo of the label on your current refill and note today's date. That's the first line of the record.
