Sleep Quality Journal

Not another device sleep score app. Sleep Quality Journal starts with how you actually feel after waking, then helps you compare habits and device scores against your own subjective sleep quality.

Every morning, rate your sleep on a 1-10 scale and log your energy, mood, perceived sleep depth, sleep issues, and lifestyle factors such as caffeine, alcohol, exercise, dinner time, late snacks, screen time, and stress.

EXPLORE PERSONAL PATTERNS • Morning sleep quality ratings with emoji-based scoring • Trend chart for recent subjective sleep quality • Pattern Explorer showing possible positive or negative factor directions • Data-quality guidance explaining why a stable pattern may not be visible yet • Pro trend readouts, impact strength, exact factor differences, and 7-day experiments

OPTIONAL SLEEP SCORE CALIBRATION Add one sleep tracking app, such as AutoSleep, Sleep Cycle, Oura, Eight Sleep, or Apple Health, and enter its nightly score alongside yours. Sleep Journal Pro unlocks multi-source comparison, ranking, and best match. If no device score matches how you feel, that is useful too: it means your subjective journal is the baseline worth keeping.

FREE CORE, OPTIONAL PRO Basic recording, history, trends, reminders, data-quality guidance, factor direction, data backup, and one Sleep Score calibration source are free. Sleep Journal Pro is a one-time unlock for impact strength, exact factor details, Pro trend readouts, multi-source calibration, and 7-day experiments.
