Every day Menstruly tells you what is going on with your girlfriend and what would land well today. Not to dodge a fight, but to get her right on the hard days and on the best ones. You enter the dates yourself, the app never connects to her phone.
His hormonal loop closes in a day, hers in a month, and inside her month no day repeats the one before it.
For a man everything fits into one day. Testosterone is higher in the morning, lower by the evening, then night, and it starts over.
So his yesterday and his tomorrow almost coincide. He lives in one state and measures everything else by it.
Her loop is roughly twenty eight times longer, and the hormones inside it stand in a new combination every day. The same dinner, the same request, the same talk about plans land differently on different days.
He has never lived this cycle in his own body, and nobody gave him data instead of experience.
You can watch very closely, but there is nothing to compare it to: his body never had a month like this.
School said nothing about it. After that he collects the picture from random conversations, and that never becomes knowledge.
She speaks from inside her own body: today my lower back aches, today I want quiet, today I want you. Translating a sensation into the language of someone who does not live that way is hard for her too.
You enter the dates, Menstruly works out her cycle day and shows what is happening and what to do and say today.
You enter the dates yourself, once. After that you see the phase and what it means: where the energy is, where the sensitivity is, what is better postponed by a couple of days.
The app never touches her phone: nothing arrives for her and nothing is visible to her. This is your tool, not surveillance of her.
This is not an instinct you either have or lack. After a few cycles you stop needing half the prompts: you know her month the way you know your own day.
For every cycle day the app gives specifics, not general relationship advice.
On the first day of her period that means warmth, iron-rich food and the chores taken off her. Plus three things that land well that day, and a list of what not to say.
On the rise everything changes: there you need plans, a trip and the conversation you have been postponing for two weeks.
Every day has its own instruction, because the same action lands differently on different days.
One to three days before a phase change the app tells you what is about to shift.
Before the hard week, for example: her irritation threshold is about to drop, so open arguments are better closed now, while talking is still easy.
Six cycles ahead export into your phone calendar with a reminder one day before.
This is the only feature that works while the app is closed.
The app stops working from averages and shows her actual days.
One tap a day: how she is doing, five states. Once six logs are in, her own pattern appears.
Her hard days as specific numbers, her best days, and which phase is hardest for her. This differs for everyone.
The longer you use it, the less of it is average and the more of it is her.
The app never connects to her phone, reads nothing and collects nothing about her.
It knows only what you entered: the date of her last period, her cycle length and your notes.
Nothing arrives for her and nothing is visible to her. If she wants, she can log how she feels through a separate link, but that is her choice, not a condition.
You can show her this screen.
Her state changes predictably. Here is what stands behind each stretch and what it means for you.
The first people who installed the app and use it every day.
Installed it because I was tired of reading her face. First thing that got me: it warned me two days before a hard week. I moved the talk about moving in, and it went calmly.
Thought it would be another calendar. It turned out to be a daily instruction: three things to do, three things to say. You just do them.
I am 41, married for twelve years. Half of what this app says about the phases I simply did not know. Awkward, but true.
Sent her the link and she logs it herself. She likes that she does not have to explain in words, I like that the data is finally hers and not a textbook average.
Exported six cycles into my calendar. The reminder arrives on its own now, I barely need to open the app.
Asked the breakdown whether to invite friends over on Saturday. The answer came from her actual cycle day, not from generic internet advice. I did not invite them, and I was right.
Setup takes a minute: her name, the date of her last period, cycle length. After that the app runs by itself and speaks up only when it matters.
