Cosia turns your health data into insights that actually mean something. Understand your cycle, energy, sleep, mood and what your body is telling you today.
Hi, I'm Maya, founder of Cosia.
I built Cosia because I was tired of tracking my body and getting nothing back. Generic charts. Vague predictions. Data that sat there without ever telling me anything useful about me. Cosia is different. It's a personalised health companion for women that takes what you already track, like your cycle, sleep, energy, and mood, and turns it into insights that actually reflect your body, your patterns, and your life.
What Cosia does for you
• Understand your cycle beyond dates. See how each phase of your cycle shapes your energy, sleep, focus, and mood, and learn what's normal for you, not just a textbook.
• Find patterns you couldn't see before. Cosia connects the dots across your data, so you finally understand why some weeks feel off, why you sleep better at certain times, or why your energy shifts.
• Get personalised insights, not generic advice. Every woman's body is different. Cosia adapts to yours, giving you guidance that's grounded in your data, not averages from a million strangers.
• Learn as you go. Short, evidence-informed explanations about hormones, cycles, and women's health, in plain language, without the pink-washing.
• Track what matters, skip what doesn't. A clean, calm interface designed to fit into real life, not demand more of it.
Why we built Cosia
Women's health has been under-researched, oversimplified, and often ignored. We believe you deserve better than period predictions that don't match your reality or wellness tips that could apply to anyone. Cosia is for every woman who's ever thought "something is going on with my body and I wish I understood it." Whether you're new to tracking or you've been logging data for years, Cosia helps you make sense of it.
Your data, protected
Your health data is deeply personal, and we treat it that way. Cosia is built and operated in Germany under strict GDPR standards. We don't sell your data. We don't share it with advertisers. It belongs to you, full stop.
Built with women, for women
Cosia is independent, women-led, and built in Berlin. We're a small team who cares, and we're only getting started.
