Yuni is a 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. An account is optional: without one your entries stay on your phone. Sign in and Yuni stores them on its servers, so you get them on your other devices and a partner you connect sees them. Available on iOS with Apple Watch support, and on the web in any browser.

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 works with no account and no email. You enter her last period date and your entries stay on that 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?
You start with 3 free days, then Yuni Premium. On the web it's $39.99 a year, $6.99 a week or $12.99 a month, and one plan covers you both once you pair. The iPhone app is free to download, with in-app purchases: $39.99 a year, $6.99 a week or $99.99 once.
