Two engineers in Istanbul. We built the site after reading the 2024 Harvard sleep study that shows timing beats talent. We keep the code open on GitHub so you can check the math.

Why We Skip the Fluff

You want answers, not stories. Our servers handle 120 k queries a day and return each result in under 200 ms. Fast is respectful.

Data We Use

We update the calculators every quarter with the latest 2024–2025 circadian research from Northwestern and Oxford. If the science shifts, the code shifts the same day.
