How we review
Period Tracker Apps is run by the team that makes Hello Phase, the app ranked first on this list. We checked every app against its store listings, pricing, privacy label, PCOS claims and recent reviews from people with PCOS on 26 October 2026, without hands-on testing of each one, and medical facts come from the WHO, the 2023 international PCOS guideline and US health agencies. There are no affiliate links, and our review method explains how we rank our own app.
Our pick
Hello Phase Our app
Best for logging PCOS cycles and symptoms on Android- Shows each predicted period as a range that widens when your cycles vary
- Logs acne, bloating, fatigue, cravings and mood, plus a daily note
- Needs no account, with a free PDF of your cycle lengths for your doctor
Quick answer. Hello Phase is the best PCOS app on Android for keeping a record of your cycles and symptoms to bring to your doctor, because it shows each predicted period as a date range that widens when your cycles vary, logs acne, bloating, fatigue, food cravings and mood with a note for anything else, and exports a free PDF of your cycle lengths, all without an account. Clue is the pick on iPhone, with a place to record a PCOS diagnosis, and Bearable is best if you want to rate how bad each symptom is. If you are trying to get pregnant, Inito and Mira measure hormones in urine instead of guessing from dates, and no app can diagnose PCOS.

What is PCOS, and why is it now called PMOS?
Polycystic ovary syndrome is a hormone condition that the WHO says affects an estimated 10 to 13% of reproductive-aged women, with up to 70% of affected women undiagnosed. Common signs include irregular or absent periods, trouble getting pregnant, extra hair on the face or body, thinning scalp hair and acne, and the WHO notes that some women with PCOS do not have polycystic ovaries at all.
On 12 May 2026 an international group of 56 academic, clinical and patient organizations announced in The Lancet that the condition is being renamed polyendocrine metabolic ovarian syndrome, or PMOS, because the old name implies ovarian cysts and hides its hormone and metabolic sides. A 2026 commentary for US gynecologists says the diagnostic criteria remain unchanged, and since most people and most apps still say PCOS, this guide uses both names.
How is PCOS diagnosed?
There is no single test for PCOS. Under the 2023 international guideline, adults need two of three features, after other causes are ruled out, namely irregular cycles or not ovulating, signs of high androgens such as excess hair growth or acne or high levels on a blood test, and polycystic ovaries on ultrasound or a high AMH level. Teens need both irregular cycles and high androgens, and the guideline defines irregular cycles by how long ago your first period was.
| Time since your first period | Cycles count as irregular when they are |
|---|---|
| Under 1 year | Irregular cycles are normal at this stage |
| 1 to 3 years | Shorter than 21 days or longer than 45 days |
| 3 years to perimenopause | Shorter than 21 days or longer than 35 days, or fewer than 8 cycles a year |
The guideline also says ovulation problems can happen even with regular cycles, and that a blood progesterone test can confirm whether you ovulated. After a diagnosis, the WHO recommends blood tests for insulin resistance and heart risk, because PCOS raises the risk of type 2 diabetes.
What should you track if you think you have PCOS?
No health agency publishes an official PCOS tracking list, so we built the one below from what the guideline and the Office on Women's Health say a doctor looks at.
| What to track | Why a doctor asks |
|---|---|
| The start date of every period | Cycle length and the number of periods a year are part of the definition of irregular cycles |
| The age you had your first period | The guideline judges cycles differently in the first years after it |
| Excess hair, acne and scalp hair loss | The guideline says your own assessment of unwanted hair, and possibly acne and hair loss, is highly valid |
| Weight and waist size | The Office on Women's Health says your doctor will measure your blood pressure, BMI and waist size |
| Mood and anxiety | The guideline says depression and anxiety symptoms should be screened for in everyone with PCOS |
| Family history of PCOS or type 2 diabetes | The WHO says women with this history are at higher risk |
Do ovulation tests work with PCOS?
Not always. In PCOS the hormone LH that ovulation tests look for can be normal or high, and a 2025 study from Massachusetts General Hospital notes that most home kits were made for people with regular cycles and a predictable surge in the middle of the cycle. Several of the companies that sell these tests, including Premom, Mira and Inito, say on their own sites that high LH in PCOS can cause repeated or false positive results.
Temperature tracking has limits too, because your temperature rises after ovulation, and one review found that ovulation dated by basal body temperature matched the LH surge within a day in only 22.1% of cycles. The guideline makes no recommendation on home LH or temperature tests for PCOS, and it names a blood progesterone test as the way to confirm ovulation.
Is there evidence that PCOS apps help?
Very little. A 2025 study rated 15 free PCOS apps on Google Play at an average of 3.6 out of 5, with AskPCOS from Monash University scoring highest, although the search was run from Iran and covered free Android apps only. We found no independent study that tests the accuracy of any US PCOS app, and the studies of the Clue and Flo PCOS features were written by people who work for those companies.
AskPMOS, the new name for AskPCOS, comes from the team behind the international guideline and includes a symptom tracker, but on the US App Store it has a 1.0 rating from only 2 ratings, so we mention it here instead of ranking it.

How we picked the apps
We started from the apps people with PCOS mention most in recent US reviews and the apps that name PCOS or PMOS in their own listings, then checked each one's PCOS features, US price, privacy label and medical claims. Hello Phase ranks first on Android for a free, account-free cycle and symptom record, Clue ranks second as the free pick on iPhone, and we left out diet apps that lock every feature behind a subscription or make claims the guideline does not support.

If you want a record to show your doctor
Months of period dates and symptoms are what you can bring to an appointment that a single blood test cannot show. These three apps are built for logging, and none of them claims to diagnose PCOS.
Hello Phase
Best for logging PCOS cycles and symptoms on Android- $39.99 for optional Plus
- Android
- No Play rating yet, 1K+ installs
- Privacy declaration
- Play "No data shared", some data collected
What stands out
- Hello Phase is our app, and it shows your next period as a date range that gets wider when your recent cycles vary, with a line that says how many cycles it learned from. Inside the app, it says cycles that are often shorter than 21 days or longer than 35 days, or a very late period, are worth raising with a doctor.
- Each day you can log flow, one of 8 moods and any of 16 symptoms, including acne, bloating, fatigue, food cravings, anxiety and low libido, and a free note field holds what the app has no button for, such as hair changes, weight or an ovulation test result. Once you have logged enough days, the free plan shows the top pattern in your symptoms each cycle.
- You can export every logged day as a CSV file or a one-page PDF summary that lists each cycle's start date, cycle length and period length, free and without an account.
Watch out for
- It is Android only, with no Google Play rating yet, and symptoms are marked present or absent with no severity scale. The full doctor report with your shortest and longest cycle and symptoms by phase is part of Plus.
- Predicted cycles are kept between 21 and 45 days and gaps over 90 days are left out of the forecast, so very long PCOS cycles will be predicted early. Its hormone chart and fertile window assume you ovulate 14 days before your next period, which may not happen with PCOS, so treat them as a sketch.
See the pricing page and the Hello Phase FAQ. All symptom patterns are part of Plus.

If you are trying to get pregnant
With PCOS you may not ovulate every cycle, and the WHO lists difficulty getting pregnant among its signs, so these four apps measure a body signal instead of counting days. Keep in mind the limits of LH and temperature tests in PCOS described above, and that only Natural Cycles is FDA cleared as birth control.
Natural Cycles
Temperature tracking with a PMOS statement- $149.99
- iPhone, Android
- 4.79 (30,293) App Store
- 4.4 (23.5K) Google Play

What stands out
- Natural Cycles says "Yes, you can use Natural Cycles if you have PMOS", that its effectiveness does not change, and that the app can identify atypical cycles or show if your cycles are irregular, which it calls helpful information to bring to your doctor. It reads your temperature from its own NC° Band or a wearable such as Apple Watch or Oura Ring.
Watch out for
- Natural Cycles says you may get more Red Days with PMOS, when it tells you to use protection, temperature confirms ovulation only after it happens, and it is the most expensive app here.

Watch out for
- A 2025 App Store reviewer said a PCOS warning was used to push a paid membership, another in September 2026 titled their review "Premom Paywalled my Data", and in May 2023 the FTC announced a proposed order barring Premom from sharing health data for advertising.

If you want answers or treatment
A symptom checker can suggest that it is worth asking about PCOS, and a care team can test and treat you, but neither replaces an in-person exam when you need one.

Find the right app for you
Apps we left out and why
Most apps built only for PCOS are diet and weight apps, and we left them out. PCOS Polly says all of its features require a subscription, PCOS Pal and Briom are paid meal plan apps whose reviewers complained about the cost, Cysterhood sells "the proven PCOS Weight Loss Method" and a "PCOS type" that the 2023 guideline does not describe, and PCOS Tracker App by Healthium promotes a carnivore diet with claims about detoxing and anti-aging.
How to choose
If you suspect PCOS, start with a tracker that makes a clear record of your period dates and symptoms, such as Hello Phase on Android or Clue on iPhone, and take it to a doctor, since diagnosis needs an exam and often blood tests. If you are trying to get pregnant, a hormone monitor like Inito or Mira tells you more than an LH strip alone, and if you cannot get PCOS care nearby, Allara treats it online in most US states.
Questions people ask
What is the best app for PCOS?
On Android, Hello Phase is the best app for keeping a free record of PCOS cycles and symptoms for your doctor, with date ranges that widen when your cycles vary and a PDF of your cycle lengths, without an account. Clue is the pick on iPhone, Bearable is best for rating symptoms by severity, Inito and Mira measure hormones if you are trying to get pregnant, and Allara offers treatment online.
Can an app tell me if I have PCOS?
No. Under the 2023 international guideline, diagnosis needs two of three features, including irregular cycles, signs of high androgens and polycystic ovaries or a high AMH level, after a doctor rules out other causes. Apps such as Flo's Symptom Checker or Premom's self-assessment can only suggest that it is worth asking.
Is PCOS now called PMOS?
Yes. In May 2026 an international group announced in The Lancet that polycystic ovary syndrome is being renamed polyendocrine metabolic ovarian syndrome, or PMOS, with a transition period. The diagnostic criteria have not changed, and many apps and doctors still use PCOS.
Do ovulation tests work if you have PCOS?
Sometimes, but LH can be normal or high in PCOS, and makers of LH tests, including Premom, Mira and Inito, say high LH can cause repeated or false positive results. Inito says it confirms ovulation using PdG, a urine marker of progesterone, and the guideline names a blood progesterone test for confirming ovulation.
What should I track before a PCOS appointment?
Track the start date of every period, the age you had your first period, any excess hair, acne or scalp hair loss, your weight and waist size, your moods, and any family history of PCOS or type 2 diabetes. These come from what the guideline and the Office on Women's Health say a doctor looks at.
Can a period tracker predict periods with PCOS?
Only roughly, because PCOS cycles can be long and uneven. Look for an app that shows a date range and how many cycles it learned from, such as Hello Phase or drip, and keep logging, since a record of your real cycle lengths matters more to your doctor than any forecast.
Is there a free PCOS app?
Hello Phase, Clue and Bearable have free versions that log cycles and symptoms, and AskPMOS from Monash University, which wrote the international guideline, is free but has only 2 ratings on the US App Store. Inito's app is free, but its monitor and strips are not.
Try Hello Phase
Hello Phase is free on Android with no account, no ads and no third-party trackers, and it keeps a record of your cycles and symptoms that you can export for your doctor.
