Best PCOS Apps
The best PCOS apps range from clinical telehealth to symptom trackers. Here is how they compare and where a private offline planner fits for irregular cycles.
There is no single best PCOS app, because the category covers three different jobs. If you want real medical care, Allara is a telehealth service where clinicians and dietitians actually treat PCOS. If you want a free tracker that handles irregular cycles gracefully, Flo has a dedicated PCOS mode. And if you want a private, offline place to log cycles, symptoms, supplements, meals, movement and lab results and then hand your doctor the pattern, PCOSWellnessOS is a $23 one-time file that keeps everything on your own device.
| Tool | Best for | Price | Subscription | Works offline |
|---|---|---|---|---|
| PCOSWellnessOS | Private, offline tracking you bring to your doctor | $23 one-time | No | Yes |
| Flo | Free tracking with a PCOS-adjusted algorithm | Free plus premium | Optional | No |
| Allara | Actual telehealth care for PCOS | Billed monthly, may take insurance | Yes | No |
| Nara | AI-assisted food and nutrition logging | Check current pricing | Likely | No |
| Stella | Menopause support, not PCOS | Via employer or insurer | Via sponsor | No |
The three jobs, and which tool does each
People search for a PCOS app wanting very different things. Some want a clinician, because they need a diagnosis, medication or a real treatment plan. Some want a free tracker to log symptoms and irregular periods. Some want a private, structured system they control, so their sensitive hormone and lab data does not sit in a cloud period app.
No product does all three well, so the honest move is to match the tool to the job. A telehealth service is care. A free app is convenient tracking with a business model behind it. A local planner is a private record you own. The sections below are organized that way.
1. PCOSWellnessOS - best for private, offline tracking you bring to your doctor
PCOSWellnessOS is a single HTML file you download and open in your browser. There is no account, no login and no cloud. Every input saves locally to your device, and Ecuato never receives it, because nothing in the file sends it anywhere. For data as sensitive as cycle, symptom and lab history, that architecture is the point.
It has seven working tabs. Cycle is built for irregular periods: you log start, length, flow, ovulation signs and basal temperature, and it shows your real average even when cycles run 35, 60 or more days, instead of assuming a tidy 28-day loop. Symptoms covers the daily reality of PCOS, including acne, hair loss, hirsutism, fatigue, mood, sleep, bloating, cravings, anxiety and brain fog, each with a severity score so you can spot patterns. Supplements is a schedule for inositol, NAC, vitamin D, magnesium, omega-3, berberine, spearmint and anything your practitioner prescribes, with dose, time of day, a with-food flag and adherence streaks. Meals is a PCOS-friendly food log built around insulin resistance, with a protein-first plate method, low-glycemic carb tracking and swap ideas. Movement logs strength, walking, yoga and low-intensity cardio with a strain score, so you can avoid the overtraining that backfires for many with PCOS. Labs tracks AMH, fasting insulin, HOMA-IR, glucose, A1C, the LH to FSH ratio, total and free testosterone, DHEA-S, SHBG, prolactin, TSH and vitamin D, with date stamps for a real trend line. Settings holds your profile, diagnosis date and target metrics, plus JSON export, import and full reset.
It costs $23 once, with no subscription and no expiry, and works on laptop, iPhone and Android home screens, fully offline after the first load.
Where it loses, honestly: it does not remind you, it has no AI, no community and no cloud sync, and it will not diagnose or coach you. Because your data lives on the device, backing it up with the JSON export is your job, and it is a tracker and journal, not medical advice. If you want a clinician or an algorithm doing the thinking, pick one of the tools below and use this to hold the record.
2. Flo - best free tracker with a real PCOS mode
Flo is the largest women’s health app, and it takes PCOS seriously. Its dedicated PCOS mode changes the prediction logic rather than bolting on a label: it widens the fertile window, accounts for anovulatory cycles and stops treating a late period as an error. It offers a large set of loggable symptoms, including PCOS-specific ones like hirsutism and acne, plus a medically reviewed content library and an anonymous community. The free tier covers ordinary tracking, and Flo Premium is an optional subscription for deeper reports.
Flo also offers Anonymous Mode, which lets you use the app without linking your name or email to your data, available to everyone at no extra cost.
Where it loses: it is a cloud service with a data-driven business. Flo settled with the FTC in 2021 over sharing sensitive health data with third parties, and in 2025 a related class action was settled for $56 million. The company changed its practices and Anonymous Mode is a credible response, but if you want zero server involvement, no cloud app can offer that.
3. Allara - best for actual medical care
Allara is not a tracker, it is telehealth. You work with a dedicated care team, which can include board-certified OB-GYNs, endocrinologists and registered dietitians, through scheduled video visits focused on hormonal and metabolic conditions like PCOS. It accepts many major insurance plans, which can lower the cost substantially, and it offers self-pay programs billed monthly for people without coverage. If what you actually need is diagnosis, medication management and a professional plan, an app cannot replace this, and Allara is built to be the real thing.
Where it loses: it is a recurring medical cost, not a $23 tool, and it is care rather than a self-managed logbook. It is also a clinical service that holds your health records, which is normal for telehealth but is the opposite of a local, private tracker. Many people use a service like Allara for the care and a private planner to hold their own day-to-day data between visits.
4. Nara - best for AI-assisted nutrition logging
Nara is an AI-powered nutrition and health tracking app: you describe or photograph what you eat and it estimates the nutrition breakdown, which lowers the friction of food logging that trips up most people. Since diet is central to managing insulin resistance in PCOS, an easy food log can genuinely help, and the AI-assisted approach is its main draw.
Where it loses: Nara is a general nutrition tool, not a PCOS-specific program, so it does not track cycles, symptoms, supplements or labs the way a dedicated PCOS planner does. It is also an account-based app that processes your data in the cloud, and its plans and pricing change, so confirm the current cost and privacy terms before you commit. Treat it as a food-logging companion, not a full PCOS system.
5. Stella - a correction, because it is a menopause app
Stella, from Vira Health, gets grouped with hormone-health apps, so it is worth being clear: it is a menopause support product, not a PCOS tool. It uses cognitive-behavioral techniques, coaching and lifestyle content for the menopause transition, and it is delivered mainly through employers, insurers and other partners rather than sold directly to consumers. It is a legitimate, well-regarded app for what it does.
Where it loses for this list: it simply is not built for PCOS. If you found Stella while searching for PCOS support, that is a naming mix-up in the femtech space, and one of the other options here will serve you better.
How to choose
- Pick PCOSWellnessOS if you want a private, offline record of cycles, symptoms, supplements, meals, movement and labs that you own outright for $23 and bring to your appointments.
- Pick Flo if you want a free, polished tracker whose algorithm is tuned for irregular PCOS cycles, and you are comfortable with a cloud account.
- Pick Allara if you need real medical care for PCOS and want clinicians and dietitians, ideally through your insurance.
- Pick Nara if your main struggle is logging food and you want AI to make nutrition tracking easier, as a companion rather than a full PCOS app.
- Skip Stella for PCOS, since it is a menopause app, and look at it only if the menopause transition is your actual concern.
Track the data that changes your appointment
PCOS care improves when you show up with evidence instead of a shrug. The most useful things to log over a few months are your cycle start dates and lengths, so an irregular pattern is visible; your top two or three symptoms with a severity score, so trends stand out; your supplement adherence, so you and your doctor know what you actually took; and your lab values over time, so a change is obvious. That short, honest record is what turns a rushed visit into a real conversation.

One thing worth repeating plainly: none of this is medical advice, and no app diagnoses or treats PCOS. A tracker records what happened. If cycles are absent, if symptoms are getting worse, or if something feels wrong, the answer is a clinician, not another app. The planner just makes sure you arrive with the full story.
Frequently asked questions
What is the best app for PCOS?
It depends on what you need. If you want actual medical care, Allara is a telehealth service with clinicians and dietitians who treat PCOS, not an app you self-manage with. If you want a free tracker, Flo has a dedicated PCOS mode that adjusts its predictions for irregular cycles. If you want a private, offline place to log cycles, symptoms, supplements, meals, movement and lab results and bring the pattern to your doctor, PCOSWellnessOS is a $23 one-time download that keeps everything on your device.
Is there a PCOS app with no subscription?
Yes. PCOSWellnessOS is a single HTML file you buy once for $23, with no subscription, no renewal and no account. Flo has a usable free tier with an optional Flo Premium subscription. Allara is a paid telehealth service billed monthly, and it can be partly or fully covered by insurance. Stella is a menopause app reached through employers and insurers, not a consumer PCOS purchase.
Which PCOS app keeps my data most private?
PCOSWellnessOS is the private outlier because it has no server. Everything you log, including cycles, symptoms, supplements and lab values, is stored only in your own browser on your own device, so there is nothing to transmit or sell. Cloud apps like Flo store your data on their servers to power predictions and sync, and Flo has both settled with the FTC over past data sharing and, in 2025, settled a large class action over the same theme. Flo now offers an Anonymous Mode that reduces that exposure, but your data is still processed on their servers.
Can a PCOS app diagnose or treat PCOS?
No. None of these apps diagnose or treat PCOS, and PCOSWellnessOS is a personal tracker and journal, not medical advice and not a substitute for your doctor. Diagnosis and treatment come from a clinician, usually a gynecologist or an endocrinologist, based on exams, bloodwork and ultrasound. What a tracker does is give that clinician months of real data instead of a vague memory, which makes the appointment more useful.
Does PCOSWellnessOS track supplements and lab results?
Yes. It has a supplement schedule for things like inositol, NAC, vitamin D, magnesium, omega-3, berberine and spearmint, with dose, time of day, a with-food flag and adherence streaks. It also has a lab results tracker for markers such as AMH, fasting insulin, HOMA-IR, glucose, A1C, the LH to FSH ratio, testosterone, DHEA-S, SHBG and TSH, with date stamps so you can see the trend across months. It does not remind you or send notifications, so you log at your own pace.
Does PCOSWellnessOS work on my phone and offline?
Yes. It opens in any browser on a laptop, and on a phone you add it to your home screen from Safari on iPhone or Chrome on Android. Because the whole app is one file, it works fully offline after the first load. Your entries stay on the device you typed them on rather than syncing to a cloud.
Is Stella a PCOS app?
Not really. Stella, by Vira Health, is a menopause support app delivered mainly through employers and insurers. It is sometimes grouped with hormone-health tools, but it is built for the menopause transition, not for managing PCOS. If you specifically want PCOS support, the other options here fit better.
