Tidefern

One record across changing chapters

Tidefern brings cycle tracking, pregnancy and the first years of childhood into one product. The aim is to keep day-to-day records together as a household moves from one stage to another, without making every change a fresh start in a different app.

The in-development application separates Today, Calendar, Journey and Family views. Daily logs and private notes sit beside pregnancy appointments, milestones and childhood records.

A small record, when it happens

Cycle logging records a day and places it in a calendar. Pregnancy views organize the current week and appointments. Family records cover feeds, sleep and diapers, with growth measurements and firsts kept on a child's timeline.

Estimates come from what has been logged. They are general wellness information, not a diagnosis, treatment recommendation or form of contraception.

Choose what another person can see

Sharing is explicit and scoped by category. A partner or guardian is invited to the records they need, with controls to change or withdraw that access. Private notes remain outside partner sharing.

The sharing controls keep permission decisions alongside the records they affect.
