"I stopped having to explain the same things every month. He just gets it now."

How it works

A relationship assistant, not another health app.

01

She sets it up once

Cycle dates, preferences, favorite things. Two minutes — once.

02

He gets thoughtful texts

Simple, warm SMS updates. No app to open. No notifications to ignore.

03

Hard day? One tap

Pick what you need — space, comfort, help. Your partner gets a warm heads-up.

04

You both feel closer

Less explaining. More understanding. Better days together.

Cycle awareness

Four phases. One quietly thoughtful partner.

Menstrual

Rest, comfort, and low-pressure quality time.

Follicular

Higher energy. A great week for new plans together.

Ovulation

Social and confident. Plan a date. Leave a note.

Luteal

More reflective. Lead with patience and reassurance.

SMS-first

Partners ignore apps. They read texts.

The magic happens in the messages. Your partner gets simple, warm updates that help them show up — without ever opening an app.

  • Phase updates with gentle context
  • Birthday & anniversary reminders
  • Gift inspiration from her wishlist
  • Hard day heads-ups, on her terms
