Predictions that learn
Your next period, fertile window and ovulation, on a ring and a calendar. It starts from what you tell it and adjusts to the cycles you log — with an honest confidence badge instead of false precision.

Your cycle, predicted from day one
A few short questions and no account. Mensia gives you a first estimate straight away, then sharpens it with every period you log.
See what it doesTell it a little
Pick a mode, your age range, when your last period started and how long your cycle usually is. An estimate is fine — you can edit it later.
Log what you notice
Tap a tile on Today to log flow, pain or mood. Mensia marks the day on your calendar and works it into your predictions.
Watch it come together
Your ring, calendar and insights update as you log, and reminders arrive before your period or your fertile window.
Everything in one calm place
Built around your body, not your data
Every prediction, pattern and chart is worked out on the phone. The app never needs to see your health data to be useful, so it never does.
Log it in seconds
Flow, pain, mood, discharge and body symptoms, sleep, water, exercise and notes, for any day. Trying to conceive adds basal temperature and LH tests; menopause adds a one-tap hot-flush log.
Patterns you would miss
Mensia notices symptoms that keep arriving before your period, and shows your average cycle, its variation and a symptom heatmap by phase once you have logged two cycles.
A doctor report in one tap
A clean PDF of your cycles, symptoms and the questions you want to ask, with a switch for each section. Share it or save it — it is made on the phone.
Locked, and discreet
Open it with a PIN, your face or your fingerprint. Switch to a neutral flower icon, and to reminders that only say “Time to check in”.
Learn, without the noise
Plain-language articles on your body, fertility, pregnancy and menopause, a PCOS self-check, when-to-see-a-doctor lists with a call button, and helplines. Not a diagnosis — a clear next step.
Six modes
One app for every phase
Choose the mode that fits your life now, and switch whenever it changes. Your history comes with you.
Track my cycle
Predictions, symptoms and patterns across every cycle, with a calendar that shows what is coming.
Trying to conceive
Your fertile window and ovulation signs, basal temperature and LH tests, and a preconception checklist.
I’m pregnant
Week by week: your baby’s size, the due date, scans and appointments, a kick counter and a contraction timer.
First period
Get ready and learn what is normal, with a period-kit checklist and myths against facts. Simpler, gentler, and no sex logging.
After birth
Recovery week by week — feeds, bleeding and mood — and a short check-in on how you are really feeling.
Perimenopause / menopause
Days since your last period, hot flushes by time of day, and your sleep and symptoms as your cycles change.

The difference
Against a tracker that keeps your cycle in the cloud
Many period trackers store what you log on their own servers, behind an account. Mensia has no server to store it on.
| Aspect | A typical cloud tracker | Mensia |
|---|---|---|
| Where your health data lives | On the company’s servers | Encrypted on your phone |
| Account required | Usually | No |
| Who can read your logs | You, and the company that stores them | Only you |
| Deleting your data | A request, and trust it was done | Delete everything, in one tap |
| Works offline | Often needs a connection to sync | Yes, all of it |
| App lock and discreet icon | Sometimes, often paid | PIN, face or fingerprint, and a flower icon |
| Cost | Free tier, then a subscription | Free, no subscription |
Our promise
Your cycle is some of the most personal information you have. Mensia keeps it on your phone, encrypted, and has no server to send it to.
No account to create, nothing to sync, nothing to sell. The only things that leave the phone are anonymous crash reports and usage counts — never your health data — and you can switch those off.

FAQs
Quick answers
What people ask before they trust an app with their cycle.
Is my health data sent anywhere?
No. Everything you log is stored on your phone, encrypted, and never uploaded — we have no server to send it to. The app sends anonymous crash reports and usage counts to Google Firebase, which never include your dates, symptoms or notes, and you can turn those off in Privacy & data.
Do I need an account?
No. There is no sign-up and no login. You can use every feature without telling us who you are.
How accurate are the predictions?
They start from the cycle length you give during setup, marked “First estimate”, and improve with each period you log — using your last six cycles and showing a confidence badge. Cycles vary, so treat them as a guide, never as contraception.
What happens if I lose or change my phone?
Because nothing is kept on a server, your data is only where you put it. Export an encrypted backup from Privacy & data and restore it on the new phone, or turn on Include in device backup.
Can other people see that I use it?
Lock the app with a PIN, your face or your fingerprint, switch to the discreet flower icon, and turn on discreet reminders that only say “Time to check in”. Sex logging can be hidden too.
Which languages does it speak?
English, Hindi, Spanish, French, German, Italian and Portuguese. The articles are in English for now.
Is it free?
Yes. Every mode and feature is free, with no subscription and no in-app purchases. A few reading screens may show non-personalised ads — never where you log, and never for anyone under 18.
Is it a medical device?
No. Mensia helps you notice and record what is happening, and gives you a report to take to your doctor. It does not diagnose anything, and the when-to-see-a-doctor lists are there so you know when to get real care.
Tell us what would make it better
A symptom you want to log, a prediction that felt off, a language you would like — it goes to the people who make the app. Please leave out any health details you would rather keep to yourself.
