A new you, every month
LunaList helps you log your period, your mood and how you feel. It shows your next period and fertile days based on your own cycle, and always tells you why.
Six goals
Periods, planning a pregnancy, pregnancy, the pill, PCOS or menopause: whatever you choose, the screen adapts to you.
Period tracking
We calculate dates from your own cycles, not a general chart.
Next period: 10-14 Oct, most likely the 12th.
Your last 6 cycles lasted 27-31 days.
You can change your goal any time. Your old logs stay.
Based on science
The way LunaList works is based on scientific research. Here are five examples.
Every woman’s cycle is different, and it shifts a little each month. So LunaList shows your next period as a range of days and marks the most likely one.
71.3% of women have pain during their period. Choose “Tired” and the screen gets simpler: one question, big buttons, fewer words.
PAIN, 2025Even for the same woman, cycle length changes by 4.2 days on average from month to month. LunaList learns what’s normal for you from your own cycles.
Apple Women’s Health Study, 202318 of 25 popular cycle apps got a privacy warning. In LunaList it’s clearly written where your information is stored, and you can delete your account and all your information at any time.
Mozilla Foundation, 2022About half of people hold their phone with one hand. That’s why the log button and main buttons sit at the bottom of the screen.
Hoober, UXmatters 2013Daily summary
The summary isn’t generic advice. It comes from your own logs. If there isn’t enough information yet, it says so: “still an estimate”.
Every summary has four parts: where you are, what to expect, why, and what it’s based on.
For your daily tip, the last 7 days of logs are sent without your name or contact details.
The red warning only appears when seeing a doctor is recommended. A period a few days late is no reason to worry.

Privacy
Health information is the most personal kind. So we write facts, not promises: the app and our privacy policy say the same thing.
“Whatever an app knows about you, it should tell you too.”
A LunaList principleSo your logs aren’t lost when you change phones. Encrypted while sent over the internet.

No. LunaList gives information, not a diagnosis, and does not replace a doctor. If it sees something in your logs that calls for a doctor, it tells you plainly. If you are worried, always see a doctor.
