Which PCOS tracker is the best in the UK?

There's no single best — it depends on the job. If you want breadth and lifestyle features, an app like PCOS Pal fits; if you want community and courses, Cysterhood does. If you want a focused, private symptom, cycle and labs diary with a doctor-ready PDF, that's the job PCOS Diary is built for.

Does the app need to do diet or weight-loss coaching?

Only if that's what you want. Those features sit outside what PCOS Diary does — it's a clinical diary, not a coaching programme. Decisions about diet belong with you and a professional, not an app.

How to choose the best PCOS tracker in the UK

"Best" depends on the job you need an app to do, so the most useful thing isn't a ranked list — it's clear criteria. PCOS care in the UK often runs through short GP appointments, so a tracker earns its place if it helps you arrive with dated evidence. Here are the criteria that matter, an honest look at a couple of established options, and where PCOS Diary — launching GB-first — fits among them.

What actually matters in a PCOS tracker

Six things matter clinically. PCOS-specific symptom severity logging, because the signs that count — irregular periods, acne, excess hair growth, thinning hair and more — are exactly what the NHS lists as PCOS symptoms. Interval-based cycle tracking that doesn't assume a regular 28-day pattern. A place to store lab results so they aren't scattered across letters. A doctor-ready export for short appointments. Privacy, ideally on-device. And sustainable pricing you can live with long term.

The established options, honestly

As of June 2026, two apps are worth knowing. PCOS Pal is a broad app that bundles AI food scanning and wider lifestyle features (around 1,499 App Store ratings) — strong if you want everything in one place. Cysterhood is community-and-course centred with coaching and weight-loss framing (around 623 ratings) — strong if you want connection and structured programmes. Both are established and well-rated; whether they're right for you depends on whether you want that breadth.

Where PCOS Diary fits

PCOS Diary is built precisely for the focused symptom, cycle and labs diary job — and nothing else. One-tap severity for nine symptoms, interval-based cycles, a lab vault, and a one-tap doctor-ready PDF, all private and on-device with no account. The free tier covers all nine symptoms, full cycle history and your first five lab results; Pro adds PDF export and an unlimited vault from £2.99 a month, with a £49.99 lifetime option. If the diary job is what you want, it's built for exactly that.
