You don't have
to do it all.
Go inward. Protect your energy
and choose what matters.
Today
The four phases
01
Days 1–5 · Rest & reflect
The body asks for stillness. Energy is naturally low — this is not a flaw, it's a signal. Honour the release.
02
Days 6–13 · Build & begin
Oestrogen rises and clarity emerges. The ideal time to start new projects, make decisions, and move your body freely.
03
Days 14–16 · Express & connect
Peak energy, confidence, and communication. You're most magnetic now — lean into collaboration and visibility.
04
Days 17–28 · Refine & retreat
Progesterone peaks, then drops. Sensitivity heightens — a gift for deep work and honest evaluation, if you protect your energy.
How it works
01
Enter your period dates and daily observations. The more you log, the more precisely Cirén can guide you — down to your food, energy, and mood on any given day.
02
Each morning, Cirén surfaces one insight for food, movement, mood, and work — rooted in where you are in your cycle.
03
Over time, you'll begin to recognise your patterns, plan your month with intention, and stop fighting your body's natural rhythm.
Our philosophy
Most health apps extract your data and return anxiety. Cirén does the opposite — it takes the complexity of cycle biology and returns it as calm, actionable understanding. No tracking streaks. No shame. No advertisements. Just you and your cycle, in conversation.
No year-long dashboards or data exports. Only what matters today, in this phase, right now.
Every recommendation is grounded in endocrinology and nutritional research, not trends or affiliate products.
Cirén will never monetise your health data, serve you advertisements, or share information with third parties.
