Sleep Tracker That Explains Why

A sleep tracker should tell you more than how long you slept.

Most sleep apps show charts, scores, and graphs. Kim helps you ask why by connecting your sleep, HRV, workouts, food, caffeine, supplements, habits, and daily check-ins.

For wellness insights, self-tracking, and personal reflection only. Not medical advice.

Why did I sleep badly last night?
Your sleep was shorter, your resting heart rate was higher, and you logged caffeine later than usual. Want to compare this with your past better-sleep nights?
Yes. What should I look at first?
I’d start with caffeine timing, late meals, workout intensity, hydration, and your bedtime consistency.
The problem

Sleep scores tell you what happened. They rarely explain what changed.

You might know you slept 6 hours. You might know your sleep score was lower. You might even know your HRV dropped.

But the real question is usually simpler and more frustrating:

Why did I sleep badly?

Kim turns your sleep data into a conversation, so you can explore possible patterns across your own health data, daily logs, and routines.

How Kim helps

Kim connects sleep to the rest of your body.

Instead of treating sleep as one isolated score, Kim helps you look at the signals around it.

Sleep + HRV

See how sleep, HRV, resting heart rate, and recovery may move together over time.

Sleep + workouts

Understand whether hard training days, soreness, or higher activity may connect with sleep quality.

Sleep + food

Connect meal timing, calories, macros, hydration, and late eating with your sleep patterns.

Sleep + supplements

Track routines like magnesium, creatine, caffeine, or bedtime habits and compare them with sleep.

Sleep + check-ins

Compare sleep with morning energy, mood, soreness, stress, and daily reflections.

Sleep + reminders

Stay consistent with habits like supplement logging, hydration, wind-down routines, and bedtime check-ins.

Ask Kim

Ask your sleep data questions.

You do not need to stare at graphs. You can ask Kim in plain English.

Personal experiments

Run sleep experiments instead of guessing.

One bad night does not always explain much. Kim helps you test habits over time so you can learn what may work for your body.

Does magnesium affect my sleep?

Track magnesium timing, sleep duration, HRV, and morning energy over time.

Does caffeine affect my HRV?

Track caffeine timing and compare it with sleep quality, HRV, and next-day energy.

Does late eating affect sleep?

Track meal timing, calories, macros, and how your sleep changes across nights.

Does evening walking help recovery?

Track evening walks, sleep, recovery, HRV, and morning check-ins.
