iPhone
A cycle calendar for you and your family: forecasts, clear phases, a reference with sources and gentle tips for every day.
My Rhythms is a period-tracking calendar and daily symptom diary built for privacy: no required
account, no cloud sync, no social feed.
EVERYTHING STAYS ON YOUR DEVICE
Cycle and symptom data lives in a local database on your phone. Nothing leaves the device
unless you export a backup yourself — one tap to a JSON file, whenever you choose.
PHASE AND UPCOMING EVENTS, PREDICTED
Mark when your period starts and ends — the app tracks your current cycle day, phase
(menstrual/follicular/fertile/luteal), and predicts your next period and fertile window, even
if you sometimes miss a day.
DAILY DIARY
Log discharge, mood, temperature, and a free-text note for the day, tagging built-in or custom
symptoms. Days with a diary entry show a small dot on the month calendar.
MONTH CALENDAR
A clear month grid: period days shaded in a soft accent color, today highlighted, diary entries
marked with an indicator.
REMINDER
A local notification the day before your predicted period start.
YOUR OWN AVERAGES
Set your own average cycle length and period length — predictions adapt to you, not a generic
28-day assumption.
CALM VISUALS, NOT "FLOWERS"
A warm wine/aubergine palette instead of the pastel-pink-with-hearts look common in this
category.
NO ADS
No ads, no account. Your cycle and diary data only ever moves via export/import, and you
control it. (The app does send anonymous, non-health technical usage analytics — see the
Privacy Policy.)
