Sounds absurd, but it is surprisingly useful.

The Egg-Advisor will now explain why, in one minute.

Style

Not just pink.

Egg-Tracker deliberately looks different from a typical period tracker. Four themes give the app its own style: EggClipse, EggSposure, Beer and Rosé Sunset.

Simple

One entry a month is enough.

Egg-Tracker doesn’t ask how you’re feeling every day. The start of your period is enough, everything else is optional. For her and for him.

Partner

Both simply in the loop.

She shares her period start – his Egg-Tracker knows.
That way both are on the same page and can plan together with less stress.

Ribbon view

Spot patterns instead of searching the calendar

A calendar day is a date. A cycle day counts from the first day of your period. Three consecutive cycles show why that makes a difference.

Calendar and ribbon view compared. On the left, the monthly calendars for January to March 2025: cycle day 13 falls on 13 January, 9 February and 12 March and sits in a different spot of the grid each time; a zigzag line connects the three spots, and a speech bubble says “Different every time”. On the right, the same three cycles in the ribbon view: each starts with day 1, and the symptom on day 13 sits in the same spot in all three.

Private

Your data. Your device.

Cycle data stays local on your device.

Your data
stays private.
Promise.

The Egg-Advisor holds up a hand in front of a phone that shows the cycle ribbon behind a glowing shield; three crossed-out signs are running away — a megaphone, a user account and an eye above a bar chart.
