About Luna: Ciclo Menstrual & Saúde
From your first cycle to menopause, Luna changes with you. Cycle, trying to conceive, pregnancy, postpartum, motherhood, and transition: one app for every phase of your life.
Every day it creates YOUR DAY: the right thing at the right time, for your moment. And each piece of advice comes with its source.
WHY LUNA IS DIFFERENT
• It creates your day. The iron-rich lunch during menstruation, the baby's movements after 28 weeks, the strength after 40. You don't need to search: Luna brings it.
• The entire app changes with your current moment. By choosing where you are, the home screen, records, reminders, and menu change. Pregnant women don't receive a cycle screen.
• Each piece of advice shows its source: WHO, ACOG, RCOG.
• It connects what others leave out: your phase, your sleep, your symptoms, and any existing conditions. When you ask "why am I so tired?", it looks at all of that before answering. • You can communicate with her via text or voice, in Portuguese.
WHAT YOU WILL FIND
• In the cycle: menstrual calendar, phases, predictions, symptoms, PMS and fertile window.
• Trying to get pregnant: the fertile period, temperature, discharge and when it's worth investigating.
• During pregnancy: week by week, with the baby's development. Movements, sleeping on your side, weight, blood pressure, blood sugar and a list of what to bring to the appointment.
• In the postpartum period and in motherhood: your recovery, breastfeeding and safe sleep for the baby.
• In the Nest, for children from 0 to 7 years old: WHO growth curve, milestones, vaccination record and age-appropriate nutrition.
• In transition and menopause: nights, hot flashes, strength and what changes in the body.
• In all phases: the food for your moment, the dish of the day, reading labels and exams, sleep and movement.
• Unexpected signs during pregnancy, postpartum, and pediatrics: just a touch away on the home screen, and free of charge.
WHEN YOU JUST WANT TO VENT
In Listening Mode, Luna listens like someone sitting next to you: friend, mother, counselor. No clinical advice, no analysis, nothing stored in your diary.
CONDITIONS SHE KNOWS
PCOS, endometriosis, thyroid, PMDD, and sexual health. You mark what you have, and she takes that into account in everything she says.
WHAT SHE NEVER DOES
She doesn't give diagnoses. She doesn't indicate dosage. She doesn't tell you to stop or change any treatment: that's a conversation between you and your caregiver. When something deserves attention, she tells you to seek help, and explains why. Luna is not a method to prevent pregnancy.
YOUR DATA IS YOURS
What you record stays on your device. Medications, contacts, and child records don't leave it. Luna doesn't sell or share anything with anyone. You can export or delete everything whenever you want.
Start with a full 30-day free trial: a whole cycle to see if it's accurate. After that, cycle tracking, sleep monitoring, pregnancy tracking, and emergency signal monitoring remain free.
Made by a healthcare professional with over 20 years of experience. Proudly Brazilian, in Portuguese, for women worldwide.
Luna is not a medical device and does not replace consultation with a healthcare professional. Always consult a doctor for diagnosis or treatment.
Cancel anytime, directly through Google Play.
Luna is developed by Soberana AI, a Brazilian company committed to women's health and empowerment.
