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.

What boyfriends and husbands say after using Yuni.
★★★★★
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.
On iPhone: no account, no cloud, no tracking. Everything stays on your device.

What is Yuni?
Yuni is a period tracker for boyfriends and husbands. It tells you where she is in her cycle and gives you one clear action each day through all five phases: menstruation, follicular, ovulation, luteal, and PMS.
How does Yuni help me support her during her period?
Yuni reads her current phase and gives you a daily tip you can act on. During menstruation you get comfort and care ideas, during the follicular phase you get activity ideas, and during PMS you get a heads-up to tread lightly. Each of the 5 modes gives you specific advice.
Is there a period tracker for boyfriends and husbands?
Yes. Yuni is built for you, not for the person menstruating. Other trackers help her log her cycle. Yuni tells you what to do each day based on where she is, so you can show up for her.
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).
Does the iPhone app need an account?
No. The Yuni iPhone app needs no account, no cloud, and no email. You enter her last period date and everything stays on your phone. The web app at yuniapp.co.uk/app signs you in with Apple or Google so your data syncs across devices.
Is Yuni free?
Yuni is free to download and includes a free trial with full access. After the trial, a subscription unlocks daily guidance, streaks, and weekly reports. Plans start at $4.99/week or $79.99/year.
