Do you wake up feeling tired without knowing why? Noire Sleep tells you what actually happens during your nights, then helps you take back control. It listens, it measures, it explains, then it offers solutions that fit your profile. And everything stays on your iPhone. YOUR ALARM BECOMES A CHALLENGE An alarm you switch off with one tap gets switched off in your sleep. Noire's only stops once you have cleared your challenge, and you pick one of eight: type a code, solve maths, shake your phone, take a few steps, photograph a spot in your home, find a randomly drawn object, or do push-ups or squats counted by the camera. Five of them force you out of bed for good. You set the difficulty, pick one of nine alarm sounds, and it is a real system alarm: it rings even on silent. YOUR PERSONALIZED PROGRAM Sleeping badly is almost never a fate, it is a series of settings. Noire builds your program from your answers and your real nights: a few actions every day, a streak that rewards consistency and forgives one miss, and regular check-ins to see how far you have come. With Noire Sleep, you can also: • Wake up at the right moment, in a window tuned to your 90 minute cycles • Find out whether you snore, and how much, with listening that tells snoring, speech, coughing and breathing apart • Play back your night sounds, keep your favourites and follow your trend week after week • Understand your night score, built from how long you slept, when you went to bed and how often you woke • Talk to Luna, your AI coach, who knows your real nights and answers from them • Follow your sleep stages and vitals from your smartwatch • Track your sleep debt, your daily energy and your progress over 30 and 90 days • Fall asleep faster with sounds made for sleep: rain, ocean, white, pink, brown and green noise, Delta, Theta and Alpha binaural beats Your recordings never leave your phone: everything is analyzed on your iPhone, nothing is ever uploaded. Your health data stays in Apple Health, and you can export everything to CSV whenever you want. No ads, no data resale, servers hosted in Europe. Start your first Night Session tonight. Tomorrow morning, you will know where to begin. Noire Sleep is not a medical device and does not provide medical advice.
