  • Wonderful app

    Wonderful app, very easy to use. It is not only for you: you can share your record with a professional too. I like it better than the popular trackers you often see first in the store. And no subscription. Thank you for that. I like the graphic design too.

Frequently asked questions

What is PMDD?
PMDD (Premenstrual Dysphoric Disorder) is a severe hormone-related mood condition in the luteal phase of the menstrual cycle: the stretch between ovulation and menstruation. Symptoms include severe mood swings, irritability, anxiety, low mood and physical complaints. PMDD affects an estimated 3–8% of people who menstruate.
What is the difference between PMS and PMDD?
PMS (premenstrual syndrome) causes mild to moderate symptoms that do not severely disrupt daily life. PMDD is the severe form, where symptoms are intense enough to disrupt work, relationships and day-to-day life. DSM-5 classifies PMDD as a mood disorder, not as a variant of PMS.
What is the DRSP form?
The DRSP (Daily Record of Severity of Problems) is a scientifically validated questionnaire that measures 21 symptoms daily on a scale from 1 (not at all) to 6 (extreme), plus 3 interference items (yes/no: impact on work, relationships and daily life). It is the gold standard for recording premenstrual symptoms and is used worldwide in PMDD research.
What is the cyclic overview?
The cyclic overview in PMDD Tracker makes cyclic patterns in your DRSP data visible by comparing phases of your cycle. It is based on the C-PASS method (Carolina Premenstrual Assessment Scoring System; Eisenlohr-Moul et al., 2017, American Journal of Psychiatry). The app calculates this per finished cycle, once enough days before and after menstruation are filled in. The overview is not a diagnosis.
How does the PMDD Tracker app work?
PMDD Tracker lets you score 21 DRSP symptoms daily on a scale of 1–6. That takes about 2 minutes a day. You usually link that to your menstrual cycle: the app detects cycle phases, shows patterns in heatmaps and charts, and calculates the cyclic overview per finished cycle (once enough days before and after menstruation are filled in). You can also record DRSP symptoms on calendar dates without a cycle; then cyclic pattern recognition and the cyclic overview are not available. You can share PDF reports with your healthcare provider.
Can I use the app if I no longer have a menstrual cycle?
Yes. You can record DRSP symptoms on calendar dates, even without an active cycle (for example after menopause, after a hysterectomy, or with hormonal suppression). You follow symptoms over time and can share data with your healthcare provider. Without a cycle the app cannot recognise cyclic patterns and the cyclic overview does not run. The core of the app remains cycle tracking for PMDD; calendar tracking is an extra option.
Can I track my own symptoms and medication as well as DRSP?
Yes. Besides the 21 DRSP symptoms you can add up to 20 of your own symptoms (same 1–6 scale) and log up to 20 medications with name, dose, frequency and intake. Your own symptoms show in the tracker and the heatmap. Medication shows in the tracker and the PDF, not in the charts. They do not count toward the DRSP total or the cyclic overview.
Is PMDD Tracker free?
Yes. PMDD Tracker is free to download and use. There are no ads and no in-app purchases. All core functions (symptom recording, charts, the cyclic overview, PDF export and Support) are fully free.
How does the app protect my privacy?
PMDD Tracker is designed with privacy as the foundation. Data is stored first on your device (offline-first). With an account, data syncs encrypted when you are online (TLS 1.3 in transit, AES-256 on device for sensitive health fields). Data is stored in London (United Kingdom) with Row Level Security, under the EU adequacy decision. No ads, no data sales. Limited usage analytics without health content can be turned off in the app. The app is GDPR-compliant.
Which languages does the app support?
The app and this website are available in English, Dutch, German, Spanish, French, Danish, Swedish, Norwegian, Portuguese and Italian. You can switch language in the app and on this site. PDF reports follow the language you use in the app.
Can I share my data with my doctor?
Yes. PMDD Tracker generates PDF reports with heatmap, charts, day notes, cyclic overview and Support. By month or by cycle. You share them from the app using your phone’s share options (for example email or WhatsApp).
Does the app provide a diagnosis?
No. PMDD Tracker is a lifestyle intervention tracker that makes cyclic patterns visible in self-reported data. The app does not provide diagnoses. Interpretation of your data is for your healthcare provider. Always see a clinician for professional advice.
What is Support?
Support has three parts: Clear days, Support days and a letter to yourself. On clearer days you write down what works. On support days you describe what you need. On heavier days (DRSP average 4 or higher, at least 10 scores), Support today shows one action plus your letter. The plan can be shared as a PDF with people close to you.
