Sleep Quality Logger

About this app

A simple, focused way to log how you slept and see the patterns build over time.

Each night, log your bedtime and wake time, rate your sleep quality and morning mood on a five-star scale, and add a note if something stood out. Sleep Quality Logger calculates your sleep duration automatically and keeps a running streak of consecutive nights logged, so building the habit feels like progress instead of one more chore.

The Trends screen turns your entries into real insight: total nights logged, average sleep quality and mood, average and min/max sleep duration, average bedtime and wake time, and a quality chart across your last 30 nights. Separate stats for the last 7 nights, last 30 nights, and all-time make it easy to see whether a recent stretch is better or worse than your normal.

Every entry is editable, so a forgotten log or a mistyped time is a quick fix, not a lost night of data.

Features:
- Log bedtime, wake time, sleep quality, and morning mood

Sleep Quality Logger keeps your log on your device, so your sleep history is there every time you open the app.
