A Connectome scan has always been a photograph from a point in time: ten minutes in a headset, two short tasks, a direct read of the part of your brain that makes decisions. From your second scan, every result is read against your own usual range, and your lifestyle data is read against every result. What you could not do, until today, was open anything between scans.

The Connectome app is now live for members in the App Store and on Google Play. Every Monday it shows you a weekly read: what this week's lifestyle is linked to in your own scans, on your own range. It shows you which factors went into that number and which did not. It shows which lifestyle factors your readings have been linked to across all your scans. It lets you set what the read is built from, log what was going on, put the score on your home screen, and watch every scan add to your profile. And it says, on the card, the one thing we want every member to know: only a scan measures your brain.

Here is what is in it.

Your week: one weekly read, every Monday

Your week is the home screen, and it is built around one number: your lifestyle score. In the app's own words, it shows "what this week's lifestyle has gone with in your scans", placed on your own range. Fifty is a usual week. Above fifty means this week's lifestyle is linked, in your own scans, to higher prefrontal engagement; below means the reverse. It is a lifestyle score, not a brain score, which is why it carries no colour and no arrow.

• Every point, shown. The lifestyle factors your scans have been linked to are listed under the score, with the points each one added this week. The arithmetic is on the screen: 50 + 24 = 74.

• "No clear link yet." If the link between a factor and your scans is not yet clear, the app says so and leaves that factor out of the number. You are never asked to trust a number the app cannot show its working for.

• Last night, from your tracker. Between Mondays, a short card describes last night against your usual: light sleep, time awake, breathing rate. "A little above", "about usual". Described, not scored.

• Never empty, never silent. Before your first scan the home screen says so plainly: nothing is measured until you come in. After scan one it shows fifty against the cohort range. If your tracker goes quiet it says which rule was not met. The screen always tells you where you are.

• If you go quiet, it pauses. The read is built from your scans and your tracker, so if the tracker is off for too long the score pauses and tells you which rule was not met. The scan never pauses.

Available to all members from launch. Your read sits at fifty and is labelled as read against the cohort range until your second scan; from scan two it is on your own range.

For teams and clinics. Every athlete in your team, and every patient in your programme, gets a Monday read on their own phone. Nobody on your staff has to collect it, and nothing in it ranks anyone against anyone. Your view stays where it is, on the web report.

Brain profile: every scan visibly adds to it

Brain profile is the long view, and it tells you how it was built. It starts with the study: a model of how brain response was linked to lifestyle across the LUCID group. From your second scan it learns where your usual sits. From your third, each lifestyle link moves toward what your own scans show. Every scan after that adds to it, and the app says so: "Based on 9 of your scans. Scan 10 adds to it."

• Based on your scans. "Based on 9 of your scans" is the only kind of claim it makes about how personal it is. No percentage, because we cannot yet show one honestly.

• Your next scan, on the screen. Two scans to calibrate, then quarterly, with a read every Monday in between.

• Association, not cause. Headset fit and time of day are accounted for and never adapt. The profile describes what is linked in your scans, not what caused what.

Available to all members from launch. Lifestyle links appear in the profile from your third scan.

For teams and clinics. The reason to book the next scan is in the person's own hand. Three scans in pre-season, or two to calibrate a programme, then a season of Mondays read against them.

Lifestyle links: what your scans have been linked to

Lifestyle links is the part of your profile that answers "linked to what?". Each ring is one lifestyle factor: sleep pattern (how much light sleep you get), steady nights (time awake at night), night breathing (breaths per minute) and daytime load (energy burned). The longer the ring, the more of your readings' scan-to-scan ups and downs that factor has been linked to across all your scans. Tap one and it shows which measure it is linked to, switching between tasks or holding information in mind, and how much.

• Two ways round. By lifestyle factor, or by brain measure. The same links, read from either end.

• Adapting to you. From your third scan each link moves toward what your own scans show, and the screen says so: "adapting to you since scan 3".

• A model quantity, not a measurement of you. The shares describe the model's account of your scans. They are not a cause, and they are not advice. Where a link is too uncertain to show, the app says "no clear direction yet".

Available to all members from launch. Lifestyle links appear from your third scan; a factor's direction is shown only once the link is clear.

Goals: set what your read is built from

Your scan measures your brain's response during two tasks. Switching between tasks is cognitive flexibility: what most of us call multitasking is really rapid switching, your brain dropping one task, picking up another, then switching back. Holding information in mind is working memory: your brain's short-term workspace, holding a few things live while you use them. Goals lets you tick the ones that matter to you and set the balance between them. The balance shows under your score ("Weighted 60% switching · 40% memory"), decides how much each task counts in your weekly read, and applies from the following Monday. The app asks again after each scan.

Available to all members from launch. Cognitive readiness, built from a resting scan, is in development and carries no weight yet; it shows as "coming soon" in Results.

Results and Log something: your scans, in context

Results shows your brain response for both tasks against your own usual range, scan by scan, with the range drawn on the chart and anything you logged marked on the line. Each scan is within, above or below: a position, not a verdict, in neutral colour and with no percentage change. It is descriptive, and not part of the weekly score. About one in three scans lands outside your range by design.

Log something is where you tell it what was going on. Tap the plus, say what changed (a late flight, a new job), pick the kind (travel, work, illness, training, other) and whether it was once, over a period, or ongoing. On your next result it appears as a plain fact, "You logged a late flight two nights before", and the app never turns it into an explanation. When a scan reads differently from your usual, the app asks you a quick question rather than guessing.

Available to all members from launch.

For teams and clinics. The camp week, the flight, the illness get logged by the person, on the day. Context arrives with them at the next review instead of being reconstructed from memory.

Connect your tracker

The weekly read is built from your scans and your tracker, so connecting one is the first thing the app asks you to do. It takes a minute. Choose the device you already wear, WHOOP, Oura, Garmin or Apple Watch, tick the choices you are happy with, and wear it most nights.

• Sleep and activity only. Four signals: light sleep, time awake at night, night breathing rate, calories burned. Nothing is shared back to the tracker.

• Ten days before your first scan. New members start the tracker first. Booking offers dates from ten days after it starts, because the model needs ten days of your own nights to read your first scan against.

• If you go quiet, it pauses. Wear it most nights; ten days in thirty keeps your score live, and Settings shows where you stand ("27 of 30 days"). If the tracker is off for too long, your score pauses and tells you why. The exact thresholds are a tap away on the screen.

• No tracker? You can order one in the app, and it counts from the day it arrives.

Why we ask

Your tracker already knows how you slept, how hard your days were and how well you recovered. On its own, none of that says anything about your mind. A scan measures your brain directly; the tracker is what lets us read your lifestyle against it. Without the tracker, the app has nothing to put next to your scans between visits, so the weekly read cannot start.

What you get from it

• Your weekly read. Every Monday, what this week's lifestyle is linked to in your own scans, on your own range, with every point shown.

• Lifestyle Links. About three months of your sleep and activity, read against every scan, so your profile can show which factors your readings have been linked to across all your scans.

• More behind every result. The more nights your tracker has been running, the more of your own data sits behind your next scan. That is what turns "data thin" into a result that is fully yours.

• Last night, every morning. A short card describing last night's signals against your usual. Described, not scored.

Your choices

Before any tracker data flows, the app asks you three separate questions: whether your tracker data may be used for your weekly read (required for the score; kept on rolling ninety-day windows with your scan data), whether your Connectome consultant may see your results, and whether your de-identified data may be used to improve the model and for research. Nothing is collected until you answer, the app does not monitor for health problems, and you can change any choice, disconnect, or delete your data in Settings.

Available to all members from launch. Supported trackers at launch: WHOOP, Oura, Garmin and Apple Watch.

LEARN MORE: Connecting your tracker · Your data and consent

For teams and clinics. Consent is handled in the app, in three separate choices, before anything is collected. The read runs only while the tracker is worn most nights, so every person who connects and wears it is a person whose results carry more lifestyle data behind them.

Widgets: your weekly read on the home screen

If you would rather not open the app on a Monday, put the read on your home screen. The small widget shows the lifestyle score and the week; the medium adds the four factors and their points; the wide one shows both. It refreshes once a week, because the read is weekly, and it carries the same line as the card: only a scan measures your brain.

• Lock screen is off by default. A number that describes your week should be yours to show, not on your lock screen for anyone to see. Turn it on in Settings if you want it.

Available on iOS at launch.

What the app does not do

It does not measure your brain. The scan does that, in ten minutes, directly, validated with Imperial College London (LUCID preprint, not yet peer reviewed). The app keeps everything around the measurement live, and says so on the card. It does not tell you what to do: it describes, and leaves the conclusions to you. It does not show a daily brain score, a percentage change on any brain measure, or a personalisation percentage, because the evidence does not yet support them. When it does, we will say so here first.
