How you feel comes first.
The best guide is how you feel, even more than the numbers.
Wellness App
A map of your own health
begins with how you feel this morning
Precision Compass is a wellness app. Compare how you feel this morning with your sleep and heart rate records and your blood test results, and get Today’s insight. The only person you’re compared with is your past self.
Not a medical device.
Some features are available with a paid plan.
Screens show sample data.
Available on the App Store worldwide, except mainland China.
Day to day
Log how you feel in the morning, and get Today’s insight
Log how you feel this morning
Rate how your body, sleep, gut, and mind feel, each on a scale of 1 to 5. Data such as sleep and heart rate comes in from Apple Health. You can also log how you feel, water, and more from Apple Watch.
From Today’s insight, choose Today’s one step
The insight draws on yesterday’s log and your Apple Health data. Pick one item from “For today” or write one in your own words. That’s Today’s one step.
Today’s insight is free up to three times in total. With a paid plan, you can get one every day.
Look back in the evening, and your next insight builds on it
In the evening or the next morning, look back on Today’s one step with “Done,” “Partly done,” or “Skipped.” On days without an insight, you’ll still see “Yesterday’s summary” in the morning.
No login needed. As a rule, your records are stored on your phone. Features that use AI, and sharing with your counselor, work only when you’ve checked what will be sent and agreed to it.
Principles
A counselor’s way of thinking, as a day-to-day tool
Today’s insight is shaped by five principles that precision nutrition counselor Shuichiro Nakahara has shared through his counseling and podcast, and put together by AI. It’s simply one point of reference. The choice is yours.
See how it all connects.
Look at food, sleep, exercise, and your mind as connected to one another.
Subtract before you add.
Before adding something new, look for what you can let go of.
Start with the foundation: stomach, liver, gut.
The stomach, liver, and gut form the body’s foundation, so that’s where to start.
Follow the trend, not the moment.
No need to be perfect. Look at the trend over time, not one day’s result.
Observations
Things that have moved together, shown as a single line
Your own records take center stage. Things that have moved together in them are shown as a single line.
- How your body feels after a good night’s sleep
- A drink at night and your heart rate variability the next morning
- How much caffeine you have, and your sleep
The more you log, the longer the lines grow, and once a connection is clear, it’s marked “Connected.” If Apple Health already holds your past records, some connections may show up soon after you start.
For a connection you’re curious about, you can “Check for yourself” over 14 days. A calendar shows your try days and usual days.
Moving together doesn’t mean one causes the other. Without a paid plan, you can still see the names of the connections found. The lines and “Check for yourself” are available with a paid plan.
Compare
How you feel, your records, and your test results, side by side
- How you feel that day, plus your logs of meals, water, alcohol, bowel movements, and more
- Data such as sleep and heart rate variability (synced with Apple Health)
- Glucose after meals (a guide to how your blood sugar changes) and what you ate at the time (imported from your FreeStyle Libre records)
- Blood test results (more than 60 markers, shown next to optimal ranges, which are precision nutrition guides, not medical reference ranges)
The app goes as far as comparing. Reading the numbers together to understand what may lie behind feeling off, and what to prioritize, is what Blood Nutrition Analysis is for.
Cycle
Day to day, once a month, every few months
Together, the three help you find your balance over time. This app’s role is the day-to-day log.

- Day to day
- Your day-to-day log lives in this app. Keep track of how you feel and your data, and compare them with your past self.
- Monthly
- Once a month, there’s Personal Wellness Counseling. You and your counselor look back on the month’s log and how you’ve felt, and choose what to focus on next. After each session, you’ll receive a report and a recording of the session. If you agree, your app log is shared with your counselor one month at a time and used in your sessions.
- Every 3–6 months
- Every 3 to 6 months or so, there’s Blood Nutrition Analysis. Around 60 blood markers help you see where you are now. Even if you continue with Personal Wellness Counseling, each analysis is separate from the monthly plan, and the blood draw is paid separately.
Whichever you start with — the app, Personal Wellness Counseling, or Blood Nutrition Analysis — you can combine them later. Changes tend to be easier to see the more you combine them. Of course, you’re welcome to use just the app. Sessions in English are coming soon.
FAQ
Questions about the app
Is it available on Android?
For now, it’s iPhone only. Once an Android version is ready, I’ll announce it in my newsletter (in Japanese).
Is it a medical device?
No. Precision Compass is not a medical device and is not intended to diagnose, treat, or prevent any disease. If you’re worried about your health, please see a doctor.
Where can I cancel the paid plan?
You can cancel it from “Cancel or change plan” in the app. This is separate from canceling a counseling plan.
How is it different from counseling?
The app goes as far as comparing your day-to-day log. In Personal Wellness Counseling, you look back on each month with your counselor. In Blood Nutrition Analysis, your blood helps you see where you are now, every few months. Sessions in English are coming soon.
