PMDD. The luteal-phase pattern, made visible.
PMDD symptoms track your cycle, not your week — they cluster in the days before your period and lift once it starts. Leo maps every mood and symptom log to its cycle phase, so that pattern stops being a feeling and becomes something you can see and show.
Symptoms that follow your cycle, not your calendar.
The defining feature of PMDD is timing: mood swings, irritability, low mood and anxiety arrive in the luteal phase and ease after menstruation. Logged in a generic mood app, that rhythm disappears into noise.
Leo tags every entry with the cycle phase it happened in, then charts your average mood per phase across 90 days — so the luteal-phase dip shows up as a shape, not a hunch.
Mood, cycle and body on one timeline.
Cycle
Your periods map the screen into menstrual, follicular, ovulation and luteal phases — the backdrop everything else is read against.
Mood
Log mood and cravings in seconds from the hub; entries carry their cycle-phase tag automatically.
Symptoms
A 31-symptom PMDD set covers the mood, cognitive and physical pieces — log what's real for you.
In the moment
Breathing and grounding tools are one tap from the hub for the hardest luteal days.
Watchlist
Pick the symptoms you want to keep an eye on; they tick off as you log a match.
Labs
Hormone, thyroid and inflammatory panels come pinned, with your trends and reference ranges.
What ships in the PMDD hub.
Leo tracks. It doesn't diagnose.
There's no PMDD screener here — no DSM-5 criteria checklist, no score that says whether you “have” it. PMDD is diagnosed by a clinician, usually with prospective cycle charting over several months.
Leo's job is to make that record clear and organized. Everything is descriptive and on-device-first; the cycle-phase chart describes what you logged — it never predicts or advises.
Your luteal phase, on the record.
Mood and symptoms mapped to your cycle, in-the-moment coping tools, a watchlist of what matters to you, and pinned hormone labs — organized for the conversation with your clinician.
