The Best PCOS Apps in 2026, Compared Honestly

A disclosure before anything else: we make one of the apps on this list. That should make you read this more carefully, not less. So here is the rule we held ourselves to — every claim about a competitor is either a price they publish, a feature they advertise, or a theme in their public reviews, and where an app is genuinely better than us at something, it says so.

Prices below were checked in August 2026 and change constantly, particularly the discounted first-year offers. Treat them as the shape of each app's pricing rather than a quote.

The category at a glance

The complaint that runs through all of them

If you read the most recent reviews of the four biggest PCOS apps — not the headline star rating, the recent flow — you find the same two sentences over and over. The first is about the paywall: you have to pay before you can see anything. The second is about billing: I cancelled and was charged anyway, or the subscription doesn't appear in my Apple subscriptions.

This is worth naming plainly, because it is not a coincidence. PCOS skews young, is disproportionately expensive to manage, and a lot of the people searching for these apps are teenagers or uninsured. A hard paywall with no trial lands very differently on that audience than it does on, say, a productivity app — and several apps in this category have layered weekly billing on top of it, which is how a $9.99 charge becomes $519 a year.

Practical advice, whichever app you end up with: buy annual rather than weekly, check the renewal date before you confirm, and verify afterwards that the subscription appears under Settings → your name → Subscriptions on your iPhone. If it doesn't appear there, it isn't billed by Apple and you can't cancel it from there either.

PCOS Pal — the default choice, and why people still leave it

PCOS Pal is the app most people find first and the one with the deepest feature set. It tracks symptoms, food, cycles and supplements, it has been around long enough to be stable, and its headline rating is high. If you want the safest mainstream pick, this is it.

The recurring criticisms are the total absence of a free trial, food scoring that reviewers say returns different answers for the same meal, and — a small thing that tells you a lot — missing basics like water logging. The scoring inconsistency is the interesting one, because it's a design problem rather than a bug: if you ask a language model for a number, it will give you a different number each time, and users notice immediately.

Cysterhood — genuinely different, genuinely expensive

Cysterhood isn't really competing with the others. It's a coaching product with workouts and a community attached, built off a following that took years to assemble, and at $150–215 a year it is priced like one. If what you actually want is people and structure rather than a tracker, it is the only serious option here and the community is the real asset.

Two caveats. The nutrition guidance takes a firm position rather than a neutral one, which some people find clarifying and others find restrictive. And the framing throughout is weight loss — the App Store listing says so outright — which brings us to the part of this category that is most obviously broken.

The weight-loss problem

Nearly every significant app in this space is framed around losing weight. That is a defensible product decision for part of the audience, and a real failure for the rest of it. A meaningful minority of people with PCOS are in a normal weight range, and they have been hearing “lose weight” from doctors, family and software for years while their actual symptoms — cycles, skin, hair, energy, mood — go unaddressed.

It is also a safety issue. PCOS carries a substantially elevated risk of disordered eating, which makes a daily calorie total and a graded food diary a genuinely poor combination for this population. We wrote about that in lean PCOS and the advice that doesn't fit. It is the reason Facet has no calorie counts anywhere and rates meals as Steady, Moderate or Quick-burn with something to add rather than something to cut.

What actually matters when you pick one

1. Does it handle irregular cycles honestly? Open the cycle screen and look for a range and a trend, not a single predicted date. An app that confidently tells you the wrong day every month will be deleted within six weeks. More on the mechanics in why period trackers get irregular cycles wrong.
2. Does it tell you how sure it is? Any app can print “your energy is higher when you sleep more” after nine days of data. The useful ones wait, and then tell you how much data the claim rests on.
3. Can you correct it? Food AI gets plates wrong. What separates a tolerable app from an infuriating one is whether fixing it takes one tap or requires force-quitting.
4. Does it help at the appointment? A cycle-length chart and a one-page summary you can hand over changes a ten-minute consultation more than any in-app advice will.
5. Where does your data live? Reproductive health data is not ordinary data. Ask whether the app requires an account, and where the logs are stored — apps with no account and no server have nothing to leak.

So which one

If you want community and coaching and the budget is there: Cysterhood. If you want the broadest mainstream tracker and can live with paying before you see it: PCOS Pal. If you want cheap and simple: Polly or Briom, on the annual plan, never the weekly one. If you only need period logging: Clue or Flo, free.

And if the thing that has been failing you is a cycle that doesn't follow the model, or an app that keeps steering a condition with dozens of symptoms back to your weight — that is the specific hole Facet was built to fill. It won't suit everyone: our insights are deliberately slow to speak, and there's no trial at launch. But if money is the obstacle, email us and we'll send three months free, no questions asked.

Whatever you pick, one habit beats all of it: log for eight consecutive weeks. Every app on this list is only as good as the data you give it, and eight weeks is roughly where the noise starts turning into something you can read.
