The Metastory Health app
Metastory Health is an iPhone and web app for people working on the gut–brain axis. It keeps your food, sleep, digestion, movement, supplements and nervous-system check-ins in one place, reads what your ring or watch has already recorded, and helps you see how those things move together — so you and your practitioner are working from a real picture instead of a guess.

Why we built it
Most health apps hand you a number and leave. The trouble with that, in our work, is that the same symptom rarely has the same cause twice. Two people with identical bloating, fatigue or 3am waking can need opposite first moves. Matching a symptom to a fix is close to a coin flip.
What actually helps is seeing the whole picture at once — what someone ate, how they slept, what their nervous system has been doing, what their digestion has been doing — and then testing rather than guessing. That is difficult to do from memory, and almost impossible to do across four different apps. So we built one.
The body, mind and gut are not separate stories. The app is there to help you read them as one.
What it does
Tracks what matters
Food with real macros and ingredients, hydration, bowel movements, blood sugar, supplements, workouts, sleep, and short nervous-system check-ins. Each one quick enough to actually keep up with.
Reads your devices
Through Apple Health, so it works with Oura, Whoop, Garmin, Fitbit, Withings, Eight Sleep, Apple Watch, blood-pressure cuffs, glucose monitors and whatever nutrition app you already use. No second login, no extra subscription.
The Health Detective
Ask it about how you have been feeling. It answers from your own logs and your own device data, names the pattern it can see, gives you one thing to try, and is straight with you about where the data runs out.
Training and rest
Workouts built around your equipment and your week, rest timers that reach your lock screen, and the Safe Inside guided audio programme for down-regulating a nervous system that has been running hot.
Testing, not guessing
The app is honest about its own limits, and so are we. It will not diagnose you, and it will never recommend a medication. What it will do — consistently — is point you back toward two things: a functional health practitioner who can look at the whole person, and real testing.
For most people the first and most useful test is a GI-MAP stool panel, which looks at gut pathogens, overgrowths, digestive markers and inflammation. It is where the bloating, burning, irregularity and reflux stories usually get their actual answer. You can read about it and order one inside the app, or start with a consultation.
Who it is for
People already working with a Metastory practitioner who want their between-session life in one place.
People with gut symptoms who have been told everything looks normal.
People carrying a nervous system that has not felt settled in a while.
Anyone who owns a ring, a watch or a monitor and has never once used what it collects to answer a question they actually had.
Your data
Apple Health is optional and stays switched off until you turn it on, and you can disconnect at any time. Health data in Metastory is never used for advertising, never sold, and never used to train models. Deleting your account erases your profile, plan and logs from our database. The full privacy policy lists every type of data the app reads and why.
