Yuni is a free period tracker app built specifically for boyfriends, husbands, and partners. Instead of tracking symptoms like traditional period apps, Yuni tells you what cycle phase your girlfriend or wife is in right now and gives you specific, actionable guidance for that day. During menstruation, you get comfort tips. During the follicular phase, activity ideas. During PMS, a heads-up to tread lightly. Yuni calculates everything automatically — just enter her last period date and cycle length. There are no accounts, no cloud storage, and no data ever leaves your phone. Available on iOS with Apple Watch support and a free web version for any browser.

Tread lightly. Avoid big confrontations and do one practical thing before she asks.
I am on your team. What would make tonight easier?
Handle a chore before it becomes a conversation.
Do not start the serious talk tonight.
Every Sunday
What landed this week.
Yuni reads what you both wrote down — how she felt, what you tried — and writes you each a private weekly report. The moments she appreciated. The patterns neither of you noticed. One thing worth trying next week.

Day 14
Today's tip
She's at her most radiant. Plan something special tonight — she'll be fully present.
Everywhere you look.
Glanceable on your Lock Screen and Apple Watch.
A widget for every phase.
Phase, daily action, streak. Right on your Home Screen and Lock Screen.
Loved by partners.
What partners are saying.
The new Apple Watch face is unreal. Cycle day, next phase, and what mode I should be in — right on my wrist. I don't even unlock my phone anymore, I just glance.
My girlfriend is on the pill so most period apps were useless to us. Yuni has a Birth Control mode that swaps the cycle stuff for actually useful daily tips. Finally an app that gets it.
The daily check-in is the part she actually loves. It picks the right question for the phase she's in — not generic 'how was your day?' stuff. We talk more now than we did before the app.
No account, no cloud, no email signup. I entered her last period and I was done in under a minute. Everything stays on my phone — that was the deciding factor for me.
The personalized insight it generated for us was scary accurate. It read patterns I'd never noticed and gave me three things to try this week. She read it and was genuinely impressed.
Hit a 60-day check-in streak last week. It sounds small but it changed how I show up — and you can share a cycle card with her so she knows you're paying attention. Best £5 I spend.
No accounts. No cloud. No tracking. Everything stays on your device.
Be the partner you want to be.

How does Yuni help me support my partner during her period?
Yuni tracks her cycle phases and gives you tailored daily tips. During menstruation you get comfort and care suggestions, during the follicular phase you get activity ideas, and during PMS you get heads-up guidance to tread lightly. Each of the 5 modes offers specific, actionable advice.
Is Yuni a period tracker for men?
Yes. Yuni is built specifically for partners — boyfriends, husbands, and anyone who wants to understand and support their significant other through her menstrual cycle. It explains cycle phases in simple terms and gives daily guidance on what she needs.
What are the 5 cycle phases in Yuni?
Yuni has 5 modes matching each cycle phase: Extra Care (menstruation — comfort and practical support), Energize (follicular — activities and planning), Connect (ovulation — quality time and connection), Nurture (luteal — patience and calm), and Heads Up (PMS — stay low-key and tread lightly).
Is my data private on Yuni?
Absolutely. Yuni has no accounts, no cloud storage, and no tracking. All data stays on your device. There is nothing to hack or leak because nothing ever leaves your phone.
Does Yuni work on Apple Watch?
Yes. Yuni has an Apple Watch app and Lock Screen widgets so you can check her current cycle phase at a glance without opening your phone.
Is Yuni free?
Yuni is free to download and comes with a free trial that gives you full access. After the trial, a subscription unlocks premium features — daily guidance, streaks, challenges, and weekly recaps. Plans start at $4.99/week or $79.99/year.
How do I track my girlfriend's period?
Enter her most recent period start date and average cycle length in Yuni. The app calculates her current phase automatically — you don't need to update it every month.
What should I do when my girlfriend or wife has PMS?
Yuni's Heads Up mode activates automatically in the days before her period. It gives you specific guidance: stay calm, avoid confrontations, be extra patient, and do small practical things like preparing her favourite snacks or clearing your schedule for quiet time together.
Is there a period tracker app for men or boyfriends?
Yes — Yuni is built specifically for that. Unlike women's period trackers, Yuni shows you what you should do each day based on where she is in her cycle. It's designed to be used by the partner, not the person menstruating.
