The problem

Traditional calorie trackers were never built for this phase.

They don’t account for post-ovulation energy shifts, or the fact that chronic deficits drive cortisol up and metabolic rate down.

Cycle apps track your period.
Calorie apps track your plate.
Nothing bridges the two — until now.

A note from Mikaela

The same science. Now in your pocket.

For seven years I worked with a small number of women at a time — reading blood work, building individual protocols, tracking what actually moved the needle.

That work is now in code — Sérénité Active — so the same science can reach more women, every day, without a waitlist.

I built it because the formulas weren’t built for us.
