Lyora Sleep

You fall asleep late, you wake up tired, and half the sleep advice you read online is disguised marketing. Lyora goes the other way. YOUR CHRONOTYPE IN 5 QUESTIONS Lyora is built on the Morningness-Eveningness Questionnaire (MEQ) — an instrument validated in 14 languages since 1976, used in more than 5,000 publications. Five short questions identify whether you are a lark, an intermediate, or an owl. Your ideal sleep window flows from that, anchored on your chosen wake-up time. A WIND-DOWN ROUTINE THAT FITS IN 30 MINUTES Four simple steps: dim the lights, cut the screens, breathe 4-7-8, read or journal. A daily streak builds with no aggressive gamification — just a quiet counter. Four nights out of five beats ten perfect nights followed by three failed ones. A SOURCED LIBRARY Six short articles (3 to 5 minutes), each citing its sources with a direct link to PubMed. Roenneberg on chronotype. Drake on caffeine. Chang on blue light. Borbely on the two-process model. Trauer on CBT-I. Stutz on evening exercise. Watson on the 2015 AASM consensus. No promotional infographics, no life-coaching: peer-reviewed studies, told clearly. FOR HARD NIGHTS Eight looping sounds (white noise, soft rain, ocean waves, fireplace, distant storm, mountain stream, night forest, pink noise). A guided animation for 4-7-8 breathing — four cycles, about 80 seconds, parasympathetic engaged. A 20-minute timer for the "3 AM wake-up": get out of bed, soft light, no screens, come back when sleepiness returns. YOUR TRACKING Hours slept, morning energy, mood. A 7-day chart with the 8-hour target line — you see at a glance whether you are in debt, balanced, or in surplus. No shaming, no gamification. BILINGUAL FR + EN Every article, every tip, every UI string — hand-written in both languages. No machine translation. YOUR DATA STAYS YOURS No account, no server, no analytics tracking. All your data lives on your phone. Lyora works offline. NO ADS DURING SLEEP No ads between 10 PM and 6 AM. No ads during breathing exercises or article reading. No ads in your first sessions. This app will not interrupt you when you are trying to sleep.
