The best period tracker for couples in 2026
A good couples tracker lets you share only what you choose, with someone you choose, and stop whenever you like. Splash is ours, and we say so wherever it appears.
In short: Splash makes partner sharing free: your partner needs no account, and you tick exactly what they see. You share a code or link; they open it in partner mode, see a read-only view and can get gentle notifications. Flo, Clue, Natural Cycles and Apple Health also share, with different costs and limits, compared below.

The short version
- Free, encrypted, partner needs no account: Splash. Share a code or link; they open it in partner mode and can get gentle notifications.
- Big library for partners: Flo for Partners (basic version free, separate app).
- Phases only: Clue Connect (sharing your own cycle needs Clue Plus).
- Using it as contraception: NC° Partner View, part of Natural Cycles.
- Both on iPhone: Health Sharing in Apple’s Health app.
How Splash partner sharing works
- Make a free account. Sharing stores a locked copy of your snapshot, so you make a free account first. Your partner needs none.
- Pick what they see. In Settings, Partner sharing, tick categories and preview exactly what their screen will show.
- Send the code or link. Show the QR code or send the link. The secret key lives in the code, never on our server.
- They open it in partner mode. Your partner opens Splash, chooses “I’m a partner” and scans or pastes. They get a read-only ring, calendar and today’s vibe.
- Notifications, if they want them. They can turn on gentle nudges, such as when your period is near. You choose which nudges are sent.
- Pause or stop any time. Pause, set an end date or stop. Stopping wipes their copy and their app says sharing has ended.

What your partner can and can’t see
They can see, if you tick it
- Your cycle ring and period dates
- Estimated fertile days
- Mood and symptoms
- That love was logged (not details)
- Notes you choose to share
- Pregnancy week
- Today’s vibe and what helps you
They never see
- Anything you left unticked
- Your PIN, lock or photos
- Your full history or raw logs
- Your other people’s shares
- Anything at all after you stop sharing
How private is shared data?
Splash encrypts the shared snapshot on your phone with a key that exists only in your QR code or link and in your app. Our server stores a locked copy it cannot open. It can see that a share exists and which categories it includes, but not the data. Each person gets their own code, so stopping one share leaves the others alone. Exactly what our server can see.

Get Splash, freeQuestions couples ask
Can my boyfriend see my period tracker?
Only if you share it with him. In Splash nothing is shared until you make a code or link and he opens it. He then sees only the categories you ticked, read-only, and you can pause or stop at any time. Without a share, he would need your unlocked phone, which a PIN or Face ID lock prevents.
How do I share my period with my partner?
In Splash, open Settings, then Partner sharing. Make a free account, tick what they can see and preview it, then show the QR code or send the link. Your partner opens Splash, chooses “I’m a partner” and scans or pastes it. They need no account, and can turn on gentle notifications.
Is there a period tracker for couples?
Yes. Splash, Flo, Clue and Natural Cycles all have partner views, and iPhone’s Health app can share cycle data with a contact. They differ on cost, what a partner sees and encryption. In Splash, sharing is free, your partner needs no account, and you choose each category, with the shared copy end-to-end encrypted.
Can my partner see my period app without me knowing?
Not through Splash sharing. A share only starts when you create a code or link, and every person you share with appears in your “People you share with” list, so nothing is hidden from you. If you are worried someone uses your phone, add a PIN, a decoy PIN and discreet mode.
What happens to shared data if we break up?
In Splash, tap the person in your sharing list and stop sharing. Their copy is wiped straight away and their app says sharing has ended, so they keep nothing new or old from the share. Old codes stop working too. You can also set an end date ahead of time, or pause sharing instead.
If sharing does not feel safe, you never have to share. Safety and quick exit.
