Maré – Ciclo Menstrual
Cycle tracker, private
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Your cycle, encrypted on your device, with optional end-to-end protection. Period prediction, calendar and symptoms — no ads, no data selling.
Maré is a simple, private-by-default period tracker.
Your data stays on your device. If you want to sync across devices, you create an account — and even then your entries are encrypted before they leave your phone. Add a secret phrase for an extra layer, and choose whether support can help you recover it: turn recovery off and the encryption is end-to-end, so not even we can read your entries.
WHAT MARÉ DOES
• Visual calendar with real, predicted, and estimated fertile days
• Next-period prediction from your history
• Quick logging of flow, symptoms, and mood
• Cycle history with average and range
• Reminders for upcoming and late periods
REAL PRIVACY
• Your data stays on your device; cloud sync is optional
• Encrypted sync, always — with optional end-to-end protection you control
• Sign in with Apple or Google only to sync
• We don't sell your data, and the app shows no ads
• Export or delete everything anytime
HONEST ABOUT WHAT IT DOES
Predictions are estimates based on your history. Maré is not a contraceptive method and does not confirm ovulation or pregnancy.
SUBSCRIPTION
Maré Plus unlocks the app after a 30-day free trial. It's an auto-renewing subscription, monthly or yearly, billed to your App Store account; the price is shown on the subscription screen and you can cancel anytime in Settings.

2.10.0 Oct 15
You can now follow Maré on Instagram, and signing in and out is clearer.
• Maré on Instagram: a button on the Today screen takes you to our profile, @mare.app.ciclo, with app news and cycle content. Following doesn't link your account or share any entry
• Clearer sign-in: if you sign in from the plans screen, Maré now confirms it worked
• Signing out: when you sign out, this device stops getting that account's notifications
Your entries stay the same.
2.9.0 Oct 12
Maré now talks about your phase, helps you log pain and lets you set aside the months that went off track.
• Your phase today: on the Today screen, a card explains the phase you're in and brings two suggestions a day. Once you have a few cycles logged, it shows what usually shows up for you in this phase
• Pain diary: new pain symptoms (pelvic, during sex, bowel movements, urination) and the impact on your day: whether you skipped something, needed medication or the pain disrupted your sleep. It's optional
• Pain in your cycles: Patterns shows in how many cycles there was pain and how long it usually lasts
• Summary for your appointment: the PDF now includes pain days per cycle and the impact
• Unusual cycle: did a month go off track because of stress, illness or travel? Mark the cycle in History. It stays logged but leaves the average and the prediction
We also measure better how the app is used, counting only actions like opening a screen. Nothing about your cycle, your symptoms or your answers is collected.
Maré doesn't diagnose. Your logs stay the same.
2.8.0 Oct 11
Maré now supports perimenopause and postmenopause.
• Life stage: in Settings you tell Maré where you are, and it adjusts what it says. In perimenopause, it stops talking about late periods and counts the time since your last one. In postmenopause, it stops estimating dates and shows a summary of your last 30 days
• More symptoms: night sweats, palpitations, vaginal dryness, joint pain, forgetfulness and more
• Intensity: any symptom can be marked as mild, moderate or severe. It's optional
• Patterns: if you're in perimenopause or postmenopause, History compares the last 30 days with the 30 before
• Hormone therapy: log when you started and see your logs from before and after
• Summary for your appointment: the PDF includes your stage, the date of your last period and symptoms by days logged
• Maré Together: you choose whether to share your stage with the person following along. It's off by default
• Maré Plus: the plan screen was redesigned and now shows your billing history
Maré doesn't diagnose menopause. Your logs stay the same.
2.7.0 Oct 6
More privacy for Maré Together.
• Maré Together: with the lock on, the option to stop following only appears after you unlock. Whoever picks up your phone can't undo the link without your biometrics
• Usage statistics: Maré now records which features are used, to decide what to improve. Nothing about your cycle is included: symptoms, mood, flow and dates stay out, and there's no advertising identifier or cross-app tracking
• Widget: labels now appear in English and Spanish
2.6.0 Oct 1
Inviting friends and following someone in Maré Together is now clearer.
• Invite a friend: you now see how many referrals are awaiting confirmation as soon as your code is used, instead of waiting days to know it worked
• The invite code field comes with MARE- already filled in. Just type the rest, and pasting the full code works too
• Maré Together: the summary of the person you follow shows up as soon as it's updated, when you come back to the app or pull down to refresh
• Maré Together: the first summary is shared as soon as you open the Together tab after the other person accepts the invite
• Maré Together: if your account already follows someone, the app now says so clearly instead of treating the invite as already used
• Fixed: after ending a link and creating a new one, the summary sometimes wasn't shared
2.5.0 Sep 26
You can now ask for help without leaving Maré.
The new Help Center, in Settings, gathers ready answers for the most common questions: subscription, secret phrase, predictions, reminders, Maré Together. It works offline and has search.
• If a ready answer doesn't solve it, start a conversation with us right there. Write whenever you want, even without a connection, and get a notification when we reply. Conversations stay with your account and show up on any device you sign in to
• At the end of each answer, tell us whether it helped. That's how we improve the texts
• A support code, in the Help Center, identifies your account without your email — handy if you signed in with "Hide My Email"
• Deleting your account now removes everything at once: entries, support conversations and the Maré Together link
• Fixed: the card asking about your contraceptive method opened with "None" already checked, and going back without tapping saved nothing. Now nothing is checked until you choose
What you log stays encrypted. The support conversation is the only thing our team reads, and the screen says so before your first word.
2.4.0 Sep 6
Maré now calls you by name.
Tell us how you'd like to be addressed and the Today screen greets you. If you want, add the day and month of your birthday — just those, never the year — and Maré wishes you a happy birthday. The reminder is created on your device.
• Your own reminders: medication, water, exercise, whatever you need. You pick the name, the time and the days of the week, and they're kept in your account — switch devices and they come with you
• A profile photo that stays on this device only: it never goes to the cloud and no one else sees it
• Your name and birthday travel encrypted, like everything else you log: not even we can read them
Your entries and your prediction stay exactly as they were.
2.3.0 Sep 5
What you log now comes back to you.
History has a new Patterns screen: what repeats across your cycles — in how many of them each symptom showed up, and which day it usually starts — counted from what you logged yourself. An item only appears after repeating in three cycles, and the screen describes what already happened: it is not a diagnosis or a symptom forecast.
• Logging your period got fast: select several days at once in the calendar, and the app asks whether it started before today
• The symptom list grew and gained categories and search — the ones you log most rise to the top on their own
• Take your cycle to your appointment: a one-page PDF summary, or your data as a spreadsheet, both created on your device
• Your cycle day now fits in a widget on the home screen and on the lock screen, with a discreet mode that shows only the number
• The logging reminder counts your days in a row, so you don't lose the streak without noticing
Your logs and your prediction stay exactly the same.
2.2.0 Sep 4
Your subscription now belongs to your account, not to your device.
Plus now works on any device where you sign in with the same account. That's why buying asks you to sign in first: it's what lets you take Plus to another device. Restoring a purchase still works without an account, exactly as before.
• The cycle ring now explains what each color means, instead of leaving you to guess
• The week strip shows three days ahead and tells you what each mark stands for
• Screens now follow what changes with gentle motion — and they respect your device's reduce motion setting
We also fixed the details that got in the way: the day number is back in the center of today's circle, the what's new sheet no longer takes over the whole screen, signing out actually closes the account screen, the secret phrase has a button to reveal what you type, and the cards on Today always have a way out.
Your free trial now follows your account rather than the installation.
2.1.0 Aug 31
Getting started with Maré is much faster now.
Setup used to take nine steps. It now takes four, each with a back button and a progress indicator. And nothing comes pre-answered — what you pick is what you picked.
• Already using Maré on another device? You can sign in on the very first screen, without answering everything again
• We tell you upfront how the subscription works: how many days are free and what happens after
• Don't remember when your last period started? That option is back. Maré waits for your first log instead of guessing a date
• The period you tell us about now shows up on your calendar as a real entry
What left the setup didn't disappear. Birth control, reminders and invite codes now show up as cards on the Today screen, at the moment they make sense — and you can dismiss any of them.
The reminder card, for instance, only appears after your first log: before that there's nothing to remind you about. And an invite code no longer requires creating an account before you can apply it.
If you already use Maré, your logs and your prediction stay exactly as they are. You pick up right where you left off.
Settings is better organised too, with its own screen for each topic: account, cycle, reminders, plan and privacy.
And, in case you hadn't seen it yet: syncing across devices is now simple. Just sign in with the same account and your entries are there, already synced — still encrypted on your device before they go to the cloud. The secret phrase became an optional extra layer you turn on in Settings › Security. And inviting a friend is easier, with a card carrying your code and a QR.
