Building · Sleeping Better
A sleep habit tracker for the habits, not the hardware
A sleep tracker on your wrist is a very precise instrument for telling you that you slept badly, which you already knew when you woke up. It measures the outcome. What you can actually change are the four or five behaviors in the three hours beforehand, and nothing on your wrist has any idea when you had your last coffee.
Why sleeping better is hard to track
Not hard to do — that's a separate problem. These are the reasons the tracking itself tends to give out first, which is usually what takes the habit with it.
- Wearables measure the result and none of the inputs you control
- The decisive moment is 10pm, and every app looks at you at 7am
- Caffeine, alcohol, screens and bedtime all interact and get analyzed separately
- Weekend lie-ins wreck the following week and never get connected to it
Worth tracking
- Time you actually got into bed, and lights out
- Last caffeine and last alcohol
- Whether screens were out of the room
- How you felt on waking, in one number
Cadence
Two lines at night, one in the morning
What progress looks like
Two weeks of a bedtime within a 30-minute window, and the first weekend that didn't undo it
In practice
Log it in the sentence you'd have said anyway
Every operation in the app is a tool the chat can call, so sleeping better gets recorded — with its context — in the time it takes to think it.
Called 4 tools
log_check_in(habit: "bedtime", at: "22:45")log_check_in(habit: "no-screens-before-bed", status: "held")log_context(last_caffeine: "14:00")correlate_habits(a: "last_caffeine", b: "morning_score")
Every figure here was counted from your check-ins. The model picked the tools and filled in the arguments — it never estimates a streak or invents a number.
And then ask
The question your history can answer
Weeks of check-ins about sleeping better contain a genuine answer to questions you've been guessing at. The only thing that was ever missing was something willing to read them.
Ask in plain language; the model turns it into queries against your record and shows the numbers behind the answer, so you can tell a real pattern from a coincidence in eleven data points.
Called 3 tools
get_history(habit: "better-sleep", window: "6m")find_pattern(group_by: "context")compare_periods(metric: "completion")
Every figure is a count or an average over your own check-ins. The model chose which comparisons to run; it produced none of the numbers.
What it does
Set up around sleeping better
The same mechanics as every other habit, pointed at what actually matters for this one.
Targets per week, not per day
Three a week is a real goal and a daily checkbox can't hold it. Rest days get recorded as rest rather than counted as failures.
Streaks that survive a life
A missed day is a missed day. The streak that matters is the pattern over months, and one interruption shouldn't erase the evidence of it.
Partial credit
Ten minutes still counts, and gets logged as ten minutes. Half-measures are how most habits actually survive a bad week.
What predicts the days you show up
Last caffeine and last alcohol — captured alongside the tick, because that's where the explanation for a good month usually turns out to be.
Measured against your other habits
Ask whether this one is propping up another, or being crowded out by it. Cross-habit questions on request.
Caught at day three
A gap is recoverable early and much less so at three weeks. One nudge when it's still the former.
