About Sleeptly

What this is

Sleeptly is a suite of free sleep calculators and planners. Everything is grounded in peer-reviewed sleep science — primarily the CDC, American Academy of Sleep Medicine, and the National Sleep Foundation’s consensus reports.

Editorial principles

• Cite or omit. Every numeric recommendation links to a source. If we couldn’t source it, we don’t publish it.
• Not medical advice. We don’t diagnose. We don’t prescribe. If a tool suggests something, it’s an educational starting point.
• Updates dated. Every guide carries a “last updated” line. We review primary content annually.
• No paywall, no upsell. Tools are free. Ads, if any, run as a single contextual display block — never in the middle of a recommendation.

Who runs it

Sleeptly is run by Rodrigo, founder & researcher based in Lisbon, Portugal. Former special operations veteran turned software engineer. Writes about sleep from years of operating under extreme deprivation and from extensive review of the peer-reviewed literature. For the full source list, see Sources.
