Tired, but your thoughts are still wide awake? Make room for a quieter bedtime with rhythm audio, nature sounds, and a simple sleep diary. GoodSleep, known in the app as SleepCore, brings together bedtime sounds, daily records, and wake-up reminders. RHYTHM AUDIO FOR YOUR EVENING Choose monaural or binaural beats. Monaural audio can play through your phone speaker; binaural beats require stereo headphones. Enjoy gentle fade-ins, gradual changes in rhythm and volume in automatic mode, and a timer to stop playback. “Brainwave” describes the frequency ranges that inform the audio design. The app does not read or measure your brain activity. MAKE YOUR OWN SOUNDSCAPE Mix rain, ocean waves, wind, a campfire, and other nature sounds. Adjust each sound's volume to create a background you enjoy for winding down or resting. KEEP A RECORD OF YOUR NIGHTS Log your mood, activities, and physical state before bed, then record how you feel after waking. Turn your nightly entries into a sleep constellation and look back on your routine over time. UNDERSTAND YOUR SLEEP DEBT View estimates and trends for accumulated sleep shortfall. With your permission, SleepCore reads sleep records created by Apple Watch through Apple Health. Without Watch data, relevant estimates use your app records and configured schedule. Sleep stages come from Apple Watch; SleepCore does not independently detect them. SET YOUR EVENING AND MORNING Set bedtime reminders and wake-up alarms. Alarm features require the relevant system permission. ASK ABOUT SLEEP The AI sleep chat offers general information about sleep and daily routines. It requires an internet connection and does not provide medical diagnosis or treatment. SLEEPCORE PLUS The app is free to download. The full rhythm-audio bedtime flow, AI chat, and advanced sleep-debt content require a SleepCore Plus subscription. Nature-sound mixing offers a limited number of free uses; continued use requires Plus. Prices, subscription periods, and trial eligibility are shown on the purchase screen. SleepCore is for relaxation, logging, and general sleep-management information. It is not a medical device and does not diagnose or treat insomnia or guarantee sleep onset or deep-sleep duration. Audio experiences vary from person to person.
