Apps to track PMDD
and what to check first

By Ben Jonas Goedeke · 6 min read · checked against its sources · updated 13 Oct 2026

Most period apps let you tap a mood. Tracking PMDD asks for more than that, because the record has a specific job: show a doctor, day by day across at least two cycles, whether your symptoms rise before your period and fall away after it. IAPMD calls daily tracking over at least two cycles the only recognized way to a diagnosis.

This guide covers what such an app needs, what two of the biggest general period apps say about themselves, and where Tideline, which we make, fits. Facts about other apps come from their US App Store listings as we read them on 13 Oct 2026. Listings change, so check them again before you decide.

What a PMDD tracking app needs

It asks every day, on the day

The criteria call for prospective daily ratings, made as you go. An app that only asks about your period, or lets you fill in a week afterwards, won’t give you that.

It rates how strong, not only what

The DRSP, the best-studied daily chart, has people rate each symptom from 1, not at all, to 6, extreme, and asks how much the day hurt productivity, hobbies and relationships. “Irritable” on a mild day and on a day you couldn’t work are very different entries.

It covers the whole symptom list

PMDD is judged on eleven areas, four of them about mood. See the PMDD symptoms checklist. If the app has no way to log anxiety, hopelessness or feeling out of control, the record will have gaps.

It lines your days up with your cycle

Researchers compare the seven days before a period with days 4 to 10 after it starts. An app should show that comparison, not just a calendar of entries.

It gives you a report you can hand over

A doctor needs to see the daily ratings for both cycles, not only a summary sentence. Look at a sample report before you log for two months.

You know where your entries go

Mood entries about the worst week of your month are personal. Check whether the app needs an account, whether entries sit on the company’s servers, what its App Store privacy label says, and whether you can export everything. Our guide to private period trackers has a short list.

Does Flo track PMDD?

Flo’s App Store listing offers over 70 trackable symptoms and moods, support for pre-period symptoms, and cycle report summaries you can download and share with your doctor. It has an Anonymous Mode, and the app is free to download with a paid Premium tier. The listing doesn’t mention PMDD by name, and it doesn’t describe a daily severity scale or a comparison of the week before your period with the week after. If you use Flo for this, open a report early and check whether it shows your ratings day by day.

On privacy, Flo’s label on the same listing, which the developer fills in, lists purchases, location, identifiers and usage data under “Data Used to Track You.”

Does Clue track PMDD?

Clue’s App Store listing offers over 200 symptoms and experiences to track, including PMS, mood, energy, cravings and sleep, with charts of your patterns. Clue Plus is listed at $9.99 a month or $39.99 a year in the US. The listing doesn’t mention PMDD or a report for a doctor. Its privacy label lists identifiers under “Data Used to Track You.”

To be fair to both: general period apps are good at predicting your next period and logging a wide range of things. The gap for PMDD is the specific record a doctor wants, so judge them on the checklist above rather than on the number of symptoms they offer.

PMDD-specific apps and paper

A search for “PMDD” on the US App Store on 13 Oct 2026 returned more than a dozen apps with PMDD in their name. They differ a lot, so run each through the same checklist. Paper still works well: IAPMD offers its own DRSP-based symptom tracker, and we made a free printable PMDD chart you can start tonight.

Where Tideline fits

Tideline is a period and mood tracker for iPhone built around the two-cycle record. Here is what it does and what it doesn’t.

The limits are real too. Tideline reads strength from your words on a four-step scale rather than asking for a 1 to 6 rating on every symptom, so a doctor who wants a DRSP itself may prefer paper. Without an account there is no cloud copy of ours, so keep your iPhone backups on. Logging and export are free, while the doctor’s report is part of Tideline Plus, a paid subscription. And like every app here, it keeps a record; it doesn’t diagnose.

A quick test before you commit

Whichever app you pick, log for three days, including one where you feel awful and are short on time. If logging that day felt like too much, the app will leave gaps in the week that matters most. Then look at what it will show a doctor. If you can’t find your daily entries in it, keep looking.

Keep the record your doctor needs. Tideline is a period and mood tracker for iPhone: write or say one sentence a day, and after two cycles it puts the week before your period next to days 4 to 10. No account, no ads, and your entries stay on your phone. Logging is free; the doctor’s report is part of Tideline Plus, a paid subscription with a free trial.

Common questions

Does Flo track PMDD?

Flo lets you log over 70 symptoms and moods and download cycle report summaries for your doctor, according to its US App Store listing on 13 Oct 2026. The listing does not mention PMDD by name or describe a daily severity scale or a week-before versus week-after comparison, so check its report before relying on it for a PMDD assessment.

Is there an app for PMDD tracking?

Yes. Several apps on the App Store are built for PMDD, and general period apps let you log moods. Look for daily ratings of how strong each symptom is, a view of your days against your cycle, a report covering at least two cycles, and clear privacy terms.

What should a PMDD tracking app include?

Daily prompts so you rate on the day, a severity scale, the full PMDD symptom list including the four mood areas, a comparison of the week before your period with days 4 to 10, a report a doctor can read, and a way to export your data.

Can an app diagnose PMDD?

No. An app can keep the daily record a doctor needs, but only a doctor can diagnose PMDD, after reviewing at least two cycles of ratings and ruling out other causes.
