Lunara learns your rhythm from the periods you log, then tells you what is coming — your next period, your PMS window, ovulation and fertile days. Nothing else. No feed, no adverts, no upsell.
Lunara does not need a questionnaire or a subscription. It needs one date.
One tap on the day it arrives. Add flow, symptoms and mood if you want to — or do not, it still works.
It weights your recent cycles more heavily than old ones, ignores one-off outliers, and measures how much you actually vary.
A quiet notification before your PMS window opens, before your period is due, and on your fertile days. Optional, and off by default.
Built for people who wanted a tracker, not a lifestyle app.
Logged periods in solid colour, predictions dashed — so you always know what is a fact and what is a forecast.
See which symptoms cluster in which phase. "Your headaches show up mostly in your PMS window" is more useful than a number.
An assistant that can actually see your data — ask why a cycle ran long, or what to expect this week, and get an answer grounded in your own numbers.
If your cycles swing between 22 and 41 days, Lunara says so and gives you a window. It will not pretend to know a date it cannot know.
Invite someone to follow your cycle read-only, so they know when the hard days are coming. Revoke it whenever you like.
Export everything as JSON or CSV in one click, and import it back. Change your phone without losing seven years of history.
And what that usually means for you.
Hormones at their lowest. Rest, warmth and iron-rich food help.
Estrogen climbing — energy, mood and focus usually rise with it.
Peak fertility, estimated from your luteal phase rather than a textbook 28-day cycle.
Where the mood dips and cramps are most likely. Knowing it is coming changes the week.
Because the popular apps got loud, and then they got expensive.
