Learn her rhythm,
not a stereotype.

Tend is a cycle-support app for the partner. It starts with general information about menstrual cycles and replaces it, month by month, with what you actually notice about her.

No account needed for her. Nothing for her to install.

How it works

Generic information is the starting point, not the product.

Every cycle app tells you what happens to women. Tend is built to stop doing that as fast as possible, and start telling you about her instead. Everything on screen is labelled with where it came from.

Estimate

Pencil

Textbook information. Honest about being a guess.

Recorded

Ink

Something that happened, and that you logged.

Her pattern

Pink

Learned from her own history.

Getting started

Everything shown is general cycle information.

Still learning

First signals recorded. General information still leads.

Patterns forming

Her own patterns move above the general guidance.

Her pattern leads

Her history becomes the primary source.

Tend never says “she will be irritable today”. It says “in previous cycles, increased sensitivity has sometimes been recorded around this point”, with a confidence indicator attached.

Phase guide with day ranges and suggested wording
The month at a glance

The whole cycle,
in plain English.

Five phases with day ranges worked out from her actual cycle, not a textbook 28 days. Each covers what's common, what usually helps, and how desire tends to move, always naming the case where she notices nothing.

Menstrual

Cramps, backache, tiredness. Practical, low-pressure care.

Follicular

Energy often returning. A good window for plans.

Ovulatory

Estimated only. Never shown as a confirmed date.

Luteal

Consistency and a calmer house. Listen before fixing.

Late luteal

Reduce demands. Don't chase a disagreement tonight.

Something you could actually say

“Anything I can do to make you more comfortable today?”

Support that learns

Two or three things
to actually do tonight.

Mark any suggestion helped, neutral, or didn't help. Tend reorders them and tells you why it chose what it chose: “practical help has been marked helpful four times in this phase.”

Check-ins take about ten seconds and everything in them is optional. Two or three a cycle is enough, and there is no streak to keep up.

No daily diary

Tend nudges twice a cycle at most, and stops asking if you don't answer.

Calendar memory

Tap any past day to see what you recorded and how it compares.

Correctness

It refuses to invent
phases she isn't having.

Hormonal contraception suppresses or overrides the natural cycle. Most partner apps show a follicular phase anyway. Tend switches phase estimates off, says why, and stops predicting dates it cannot know.

Combined pill, patch, ring

Phases off, day count kept. A break-week bleed is named as a withdrawal bleed.

Mini pill, implant, coil

No phases and no date estimate. Bleeding is often irregular or absent.

The learning engine keeps working. It switches from cycle position to recency, and on these methods that becomes the whole product.

Her side of it

An app about her
has to answer to her.

Consent is a gate in setup, not a line in a policy. She gets a link with no account and nothing to install. She can see everything you've recorded, delete any of it, or switch you off from her side without telling you.

Never paywalled

Her access, data export and deletion are free on every plan, permanently.

No ad targeting

Cycle, symptom and mood data never goes to advertising or generic analytics.

No streaks

Caring about your partner is not a daily quest.

No intimacy reports

Tend does not track intimacy or offer “timing insights”.

Her cycle may influence how she feels physically or emotionally, but it should never be used to dismiss her feelings or assume a disagreement is “just hormones.”

Notifications

Six a cycle, one a day,
never about her mood.

Most apps notify to drive retention. Tend caps itself: one a day, six a cycle, delivered early evening because everything it suggests is for tonight. Every message carries a one-tap action.

The silences

Period and phase alerts switch off entirely on hormonal contraception.

Straight through

When she taps something on her link it ignores every cap. It's the only one carrying something she actually said.

Nothing ships that names her mood as a prediction, tells you how to behave toward her, or mentions sex.

Pricing

Free until Tend
actually knows her.

The trial is measured in her cycles, not our calendar. Nothing is charged until Tend has three of her cycles behind it and can start telling you about her instead of about women in general. That takes about three months, so that is how long the trial runs.

No weekly plan. A week's notice before any charge, then a reminder the day before.

Questions

The ones people actually ask.

Does she need to know I'm using it?

Yes, and Tend won't let you past setup without confirming it. You'll be asked to agree that she knows, that you won't use it to dismiss her feelings, and that she can see or delete anything in the app. She then gets her own link to do exactly that.

Does she have to download anything?

No. She has no account and nothing to install. If you turn her link on, she opens a web page, sees what you've recorded, and can change it, delete it, or revoke your access from her side.

What if she uses hormonal contraception?

Tend turns phase estimates off. Combined pills, implants, injections and hormonal coils suppress or override the natural cycle, so follicular and luteal phases wouldn't mean anything. Check-ins, support and learned patterns keep working, and become the whole product.

Can I use it to work out when she's fertile?

No. Tend is not a contraceptive, fertility, diagnostic or medical tool, and it must never be used to avoid or achieve pregnancy. Ovulation cannot be confirmed from dates, which is why Tend only ever shows an estimated window and says so.

Will it tell me how she's feeling?

Never. It tells you what has been recorded before, with a confidence indicator, and it says clearly that a bad Tuesday is usually just a bad Tuesday.

What happens to my data?

Sensitive entries are encrypted, never sold, and never used for advertising. You can export everything or delete any single entry, and account deletion is immediate. None of that sits behind the paywall.
