Sleep Record

Understand your nights. Improve your days.

Sleep Record is a private, local-first sleep diary that helps you see patterns in your sleep without an account, phone number, wearable, or sleep-data upload.

Build a clearer sleep picture

Record bedtime, estimated time to fall asleep, wake time, get-up time, night awakenings, sleep quality, daytime function, insomnia nights, and optional notes. Sleep Record turns those details into useful summaries you can review over time.

See trends that matter

Explore sleep duration, time in bed, sleep efficiency, quality, daytime function, sleep-onset time, and nighttime wake duration. Use calendar and chart views to compare recent nights and understand your routine.

Learn practical sleep habits

Read CBT-I-informed educational guidance, sleep hygiene suggestions, and explanations of sleep efficiency and sleep restriction. Sleep Record is designed for education and self-reflection and is not a medical device.

Relax with built-in sounds

Choose from rain, ocean waves, fan sounds, brown noise, birdsong, crickets, and cat purring. Adjust the volume and set a sleep timer.
