Breathing exercises, sleep calculators, meditation timers — tools for the moments when you need to slow down. Free forever. No sign-up.
Breathub is a free, open wellness space. No accounts. No subscriptions. No tracking. You arrive, you use a tool, you feel better. That's the entire idea.
Every tool here is built on published science — sleep cycle research, vagal nerve activation, mindfulness studies. We just made them beautiful and easy to use.
Whether you have 2 minutes or 20, there's something here for right now.
Breathub brings together the most evidence-based wellness techniques in one free, account-free space. Every tool is built on published research — from the vagal nerve science behind box breathing to the 90-minute sleep cycle research powering our sleep calculator. Nothing here is pseudoscience or wellness theatre.
The design principle is radical simplicity: arrive, use the tool, feel better. No account creation, no email confirmation, no onboarding flow. The mindfulness timer starts when you press the button. The stress assessment runs entirely in your browser. The mood tracker stores your data on your device and nowhere else.
Whether you have 2 minutes or 60, whether you need to calm down or wake up, fall asleep or find focus — there is a tool here for right now. Explore Wim Hof breathing for energy, sleep sounds for rest, or the fasting timer for metabolic health — all free, all immediately accessible.
