## Why most period apps aren't built for you

Search for a "period tracker for men" and you'll find a wall of apps designed for the person menstruating. A few — Flo, Clue, Stardust — have bolted on a "partner mode": she shares a code, you get a read-only calendar and the odd notification. It tells you *when* her period is. It never tells you what to do about it.

That's the real gap. Knowing she's in her luteal phase doesn't help you on a Tuesday night when she's quiet and you can't read why. You don't need another calendar. You need to know whether tonight calls for the hot-water-bottle move or the let's-go-for-a-walk one — and you need it without interrogating her or counting days yourself.

## How Yuni works

Setup takes 30 seconds.

### Enter her dates once

Put in when her last period started and roughly how long her cycle runs. That's the whole setup. No daily logging, no account on iPhone.

### See today's mode

Open the app and see which phase she's in and what it means for today, in plain language. Apple Watch and Lock Screen carry the day's advice.

### Know what to do

Each phase comes with specific guidance: what she likely needs, what to say, what to avoid, and when to give her space. You still mean it — Yuni just makes sure you get the timing right.

## Is it creepy to track your girlfriend's period?

It's a fair thing to ask, and the answer is in the intent. Tracking someone to control them, catch them out, or explain away every disagreement as hormones — that's not okay. Tracking so you stop forgetting her worst days, stop asking "are you on your period?", and start showing up before she has to spell it out — that's effort, and it's the opposite of creepy.

The healthiest version is the open one: tell her you're using Yuni so you can be a better partner. Most women react well to a partner who cares enough to pay attention. And because she isn't tracked or pinged, and no account means no sync, there's no surveillance here — just you, doing the homework most partners never bother to do.

## On your iPhone, with no account

Yuni needs no account on iPhone. Her cycle dates stay on your device, so there's no server to breach and no company selling reproductive health data — the exact issue behind the FTC actions against several mainstream period apps. It runs on iPhone, Apple Watch and Lock Screen widgets, with 3 free days, then Yuni Premium at $39.99 a year (£39.99 in the UK). No subscription to her app, no code, no iPhone sign-up.

## Period tracker for men: FAQ

### Is there a period tracker for men or boyfriends?

Yes. Yuni is a period tracker built specifically for the partner, not for the person menstruating. You enter her cycle dates once and it tells you which phase she's in and how to show up each day. On iPhone it works with no account, and her dates stay on that device.

### Is it free?

You start with 3 free days, so you can set it up and use it before paying anything. Then Yuni Premium is $39.99 a year (£39.99 in the UK), one plan covers you both once you pair, and the iPhone app works with no account.

### Does my girlfriend need to be on the app too?

No. Unlike Flo for Partners or Clue Connect, Yuni does not need her to install anything or share a code. You enter her cycle dates yourself, once, and the app does the rest. Nothing is sent to her, and no account means no sync.

### Is it creepy to track your girlfriend's period?

Tracking to control or check up on someone is. Tracking so you stop forgetting her worst days, stop asking "are you on your period?", and start showing up before she has to ask is the opposite — it's effort. The healthiest version is open: tell her you're using it so you can be a better partner. Most women react well to that.

### Is my data private?

Yes. On iPhone Yuni works with no account, and her cycle dates stay on that device, so there is no server to breach and no company selling the data — the issue behind the FTC actions against several mainstream period apps.
