Fuel for a changing body.
Cycle-aware macro tracking for active women in perimenopause. Built by a scientist who’s living it too.
Traditional calorie trackers were never built for this phase.

Cycle apps track your period.
Calorie apps track your plate.

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.
In their own words.
Her knowledge is vast, all backed by research and taught in an easy, practical manner. Super easy to implement the tools and tips she teaches.
From the get go, Mikaela has been attentive, supportive, showing vast knowledge and tools, to help guide me through such a life changing journey.
Mikaela was very easy to work with and always available when I needed her advice. Best money ever spent.
