Ovaly started with a simple question: Why does something as personal as cycle tracking require you to hand over your most intimate data? We couldn't find a good answer — so we built our own.
It started with a real problem. Someone close to us was frustrated — her cycle tracking app consistently missed the mark. Predictions were off. The fertile window felt like guesswork. And every time she opened the app, she was met with subscription prompts, ads, and the uneasy feeling that her most personal health data was being stored on servers she had no control over.
We asked ourselves: could we build something better? An app that actually learns your individual rhythm instead of relying on population averages? One that keeps every piece of data on your device — not because regulations demand it, but because it's the only approach that makes sense?
What started as a focused side project quickly grew into something much larger. A deep dive into reproductive biology, Bayesian statistics, and Apple's HealthKit framework. Months of research, engineering, and testing. The result is Ovaly — an app built with the conviction that privacy and precision aren't luxuries. They're the baseline.
"Women already spend enough every month. A cycle tracking app shouldn't be another expense."
Pads, tampons, pain medication, doctor visits — the financial reality of having a cycle adds up every single month. We believe that at the very least, the app that helps you understand your body shouldn't be another line item on that list.
Ovaly's core features are free, and they always will be. No trial periods, no paywalls in front of essential health insights, no ads. In the future, we plan to offer optional premium features — think customization, partner sharing, and in-depth educational content — but the predictions, logging, and calendar that make Ovaly useful? Those are yours. Forever.
Not a toggle in settings. Not a policy document. Privacy is how the app is built — on-device storage, zero servers, no analytics. We can't see your data because we designed it that way.
Ovaly tells you when it's uncertain. No fake precision, no confident predictions based on two data points. The engine is transparent about what it knows and what it's still learning.
Cycle tracking shouldn't feel like filling out a medical form. Ovaly is designed to be fast, intuitive, and — dare we say — enjoyable. Log your day in seconds, not minutes.
Ovaly is made by RKI-Benito Handels GmbH, based in Graz, Austria — right in the heart of Europe. Being an EU company isn't just a legal footnote; it means GDPR compliance is in our DNA, not an afterthought.
Our founder has Croatian roots, which is why Ovaly ships in English, German, and Croatian from day one. Not every app speaks your language. We think the ones that deal with your health should.
Ovaly is launching with a complete, polished experience — but we're far from done. Here's where we're headed:
Bayesian predictions, daily logging, cycle calendar, hormone curves, phase insights, 5 widgets, 3 languages, HealthKit integration. Free.
Educational articles, deeper cycle analytics, and a partner feature so the people who matter can stay in the loop — if you choose.
Bringing Ovaly to Android. Expanding language support. Collaborating with healthcare professionals to make predictions even smarter.
