Our mission is to help you sleep better with free tools grounded in the science of rest.
CalculaTuSueño.com was born from a simple but powerful idea: millions of people wake up every morning feeling tired without understanding why. It is not always a matter of sleeping more — it is a matter of sleeping at the right time. With that belief, we built a free and accessible tool for everyone who wants to improve their rest.
We are a team of web developers and digital health enthusiasts who believe in the power of technology to improve daily habits. Our goal is not to replace professional medical advice, but to offer a science-based starting point that helps each person better understand their own sleep patterns.
We want every person who visits our site to learn something valuable: to better understand how their sleep works and how they can improve it. We believe that rest is the foundation of a healthy, productive, and happy life — and that a simple tool like a sleep cycle calculator can make a real difference in everyday life.
All our tools are based on well-established research into human sleep. The calculator is built on the 90-minute sleep cycle model, which is widely accepted by the scientific community and endorsed by organisations such as the National Sleep Foundation and the American Academy of Sleep Medicine.
To provide recommendations that are as personalised as possible, we take into account factors such as the user's age, biological sex, sleep latency (the time it takes to fall asleep), and hormonal differences between men and women.
CalculaTuSueño.com is an informational and educational tool. Under no circumstances does it replace the diagnosis, treatment, or advice of a healthcare professional. If you experience insomnia, sleep apnea, excessive daytime sleepiness, or any other sleep disorder, we strongly recommend consulting a specialist doctor.
Our goal is to complement medical care, not replace it. Use this tool as a first step towards better understanding your sleep habits and as a starting point for a conversation with your healthcare provider.
We are constantly evolving. Every day we work to improve our tools, add new features, and expand our educational content about sleep. If you have a suggestion, an idea, or would like to share your experience with our calculator, don't hesitate to write to us. Your feedback helps us grow.
Have a question, suggestion, or collaboration proposal? We'd love to hear from you.
