Slept enough but still tired? Connect your evenings with how you feel in the morning, spot personal patterns, and try one small habit change at a time.
Still waking up tired after a full night? Baa investigates your sleep with you — clues from your own nights, one small test, and a playbook of what actually helps.
Trackers tell you what happened. Tip lists tell you what everyone should try. Baa closes the loop: what may be affecting your nights, what to test first, and whether that change actually helped you.
How it works
1. Notice — Import nights from Apple Health, or log last night in a few taps. Each morning, one check-in: how you feel.
2. Investigate — Baa looks for clues in your own data and shows the evidence in plain language, compared with your normal — not a population score.
3. Learn — Test one small change for a few nights. Keep what helps. Set aside what does not seem to matter. It lands in your Sleep Playbook.
What you can do
• See last night against your usual bedtime, time asleep, and how you woke up
• Open one investigation: waking tired, waking at night, trouble falling asleep, or a messy schedule
• Read clues with the evidence behind them — a pattern, not a verdict
• Run a single test so you change one thing at a time
• Build a personal playbook: Helps me, Hurts me, Doesn't seem to matter
• Use it with Apple Health, or with no watch at all
Baa is a sheep, and a terrible detective. The notebook underneath is careful. Early on, Baa will tell you he does not know yet. That is the point.
Baa is not a medical device and cannot diagnose or treat sleep conditions. Tests are small, reversible habit changes, not medical advice. If you suspect a sleep disorder, talk to a clinician.
Start tonight. Log one night, check in tomorrow morning, and let Baa open the case.
