FEATURES
Everything points at one moment: the appointment.
No coaching, no meal plans, no streaks. A focused clinical diary that turns months of scattered symptoms into something you can show.
TODAY
One-tap severity logging
Nine PCOS symptoms — acne, hair loss, hirsutism, fatigue, bloating, mood, cravings, headache, pelvic pain. Tap a chip once for mild, again for moderate, again for severe. The number is always visible, the whole day takes under thirty seconds, and nothing hides behind a form.

CYCLE
Strata, not a shame calendar
A 28-day grid makes a 47-day cycle look broken. PCOS Diary draws each cycle as a strip whose width is its real length, with your own typical range banded behind it. Irregularity becomes a named, expected shape — the exact thing your endocrinologist wants to see, not a wall of red dots.

LAB VAULT
A lab vault your endocrinologist will love
Testosterone, fasting insulin, HOMA-IR, AMH, LH, FSH, glucose, HbA1c. Each value lands on a trend line with the typical reference range banded in — so “is it getting better?” has a visual answer that spans years, not one printout.

DOCTOR REPORT
The report that survives a 12-minute appointment
Pick 30, 90, or 180 days and export a clean PDF: symptom frequency versus your prior period, every cycle interval, every lab trend. It reads like a clinical letter, not an app export — hand over your phone or share the file.

APPLE HEALTH
Apple Health, both ways
Already tracking your period elsewhere? Turn on Health sync and PCOS Diary imports your flow days as cycles — your strata appear instantly. Periods you log here are written back. The scope is menstrual flow only, and it's opt-in.

HOME SCREEN
Quick-log without opening the app
A widget shows your cycle day and your last cycles at their real widths. Tap a symptom right on the widget to log it — severity steps exactly like in the app. Honest by design: when your cycle length is unknown, the ring stays deliberately incomplete.
