Have a question about the Sleep Calculator, found a bug, or have a suggestion for how we can make the tool better? We would love to hear from you.
The fastest way to reach us is by email at hello@ssleepcalculator.com. We read every message and try to reply to all of them within a couple of business days. Whether it is a feature request, a report of a calculation that looks wrong, or just feedback about your experience, your input helps us improve the tool for everyone.
We are a small team, and the Sleep Calculator is a free tool we maintain alongside our other work, so we appreciate your patience during busy periods. For press or partnership inquiries, the same email address works — please include a clear subject line so your message reaches the right person.
If you are having trouble with the calculator itself, it helps to include your device and browser in your message so we can reproduce the issue. Thanks for using Sleep Calculator — and for helping us make it better.
