NuanYue – Period Tracker

NuanYue is a simple period tracker with a soft pink, Apple-style look. Everyone in the family keeps their own record.

[Record in one tap]
· Tap once when your period starts and once when it ends; add missed days later, or tap dates directly on the calendar
· The Today ring shows the whole cycle at a glance: period, next expected period, fertile window and ovulation day
· Log flow, cramps, symptoms, mood and notes

[Automatic estimates]
· After two recorded periods, your next period and fertile window are estimated from your own recent cycles
· Stats: average cycle, average period length, regularity, cycle-length bars and history

[For the whole family]
· Each person has their own profile; change the name and avatar any time (emoji or a photo)
· 8 color themes, light or dark; each person picks their own
· Optional 4-digit passcode so family members cannot see your records

[TCM intake form]
· Tick items on a Traditional Chinese Medicine intake form, item by item as on the original: cold/heat, sweating, pain, appetite and taste, bowel and bladder, sleep, activity and mood, menstruation and discharge, tongue, pattern of onset
· Items ticked under "menstruation and discharge" in a daily record can be carried into the form in one tap
· Export as a long image or an A4 PDF (full form, or selected items only); selected items are ticked and marked in red as on the original, ready to send to your doctor

[Reminders]
· A reminder 1–3 days before your period is due, at the time you choose

[Privacy]
· No sign-up, no internet access, no data collection; all records stay on your phone

Note: the app's interface is currently in Simplified Chinese. Estimates are for reference only and must not be used for contraception or as medical advice; the intake form is only a reference for your doctor and is not a diagnosis.
