Sleep Ledger
· v1.0.0
About
Sleep Ledger treats sleep like a bank account. Every night you spend against a target. Short nights build debt. Solid nights pay it down. All on your wrist — no phone, no cloud.
TWO NUMBERS THAT MATTER
— SLEEP DEBT — how far you're behind your target, in hours and minutes, weighted toward recent nights so a rough week a fortnight ago doesn't haunt you forever.
— CONSISTENCY — how aligned your wake times are, scored 0–100%. Built on circular statistics so a 23:55 wake and a 00:05 wake read as 10 minutes apart, not 23 hours.
DASHBOARD IN ONE GLANCE
Open the widget — debt on top, consistency below, a one-line status. That's the check-in.
HISTORY WITHOUT NOISE
Three full-screen charts, one swipe apart:
— 30-day debt trend — watch it climb on rough weeks and fall on good ones.
— 30-day sleep vs. target — see which nights hit the mark and which didn't.
— 30-day consistency — see the rhythm stabilise as you settle into a routine.
NAPS COUNT
Add a nap from the menu. It reduces debt at 80% — a nap restores, but not like deep night sleep.
ADJUSTABLE TARGET
Set your target between 6h and 9h in 30-min steps, on-watch or from Garmin Connect Mobile.
