Tandm

Sign in

The couples cycle app

Awareness without asking.

She tracks her cycle privately. He gets a short, plain-language note each day about what might help — never her entries, and only while she is sharing.

How it works

  1. She tracks

    A private check-in that takes a few seconds. How she is feeling, how her body is doing, anything she wants to remember. It stays hers.

  2. Tandm translates

    Her cycle becomes one short note written for him — about what this stretch of the month can be like, and what tends to help.

  3. He understands

    One card a day, in plain English, with a few small things worth doing. No charts to read and nothing to interpret.

Built around trust

What he never sees

He is never shown her entries. Not her moods, not her symptoms, not a word she wrote down. His side of the app carries short written insights and nothing else.

She decides, always

Sharing is hers to start, pause, or end whenever she likes — in one tap, without a reason. Ending it also deletes every note that was ever written for him.

Not a medical device

Tandm is not a contraceptive, not a fertility planner, and not a medical device. It can’t tell you whether you are pregnant, fertile, or protected from pregnancy. Everything here is an estimate based on the dates you log. If something about your cycle worries you — or changes suddenly — please speak to a doctor or pharmacist.
