Is your body ageing faster than you are? BaseLine measures what no other app can.
Most “metabolic age” tools guess from a formula. BaseLine uses your real blood glucose readings and your actual blood pressure data — then shows you your pattern score, detects drift before you feel it, and tells you what is actually changing in your body.
Real blood readings. Four colours. A coaching system that learns your pattern and tells you what to do next.
7 days. Know which habits are helping, which are hurting, and what to change first.
✨ Guided by Jarvis — your AI health companion
Everyone else guesses your metabolic age. We measure it.
“I'm doing everything right but I can't shift the weight.”
Online calculators say your metabolism is fine because they only know your height and weight. BaseLine tracks your actual glucose response and daily habits — showing exactly which behaviours are ageing your metabolism, and which ones are turning it around.
“I'm tired all the time but my bloods are fine.”
Your GP tested fasting glucose once. An online calculator ignored it entirely. BaseLine tracks it daily and correlates it with your sleep, habits, and blood pressure — showing patterns that a single test or a formula never could.
“I'm doing everything right but nothing's changing.”
Without data from inside your body, you're guessing which habits matter. BaseLine ranks them by measured impact on your actual readings — so you stop doing everything and start doing what works.
“There's a family history I want to get ahead of.”
Cardiovascular and recovery markers shift gradually. BaseLine shows the trend before symptoms appear — giving you visibility while there's still time to act.
You've probably seen a biological age calculator online. You entered your height, weight, and age — and it told you a number based on a formula from the 1990s. It didn't measure anything. It estimated your calorie burn and compared it to a population average.
That's not health tracking. That's maths.
BaseLine is different. It uses your actual blood glucose readings, your real blood pressure, and the habits you log every day — then calculates markers like pulse pressure, cardiovascular load, and glucose variability that no formula can reach. It watches your trend over weeks, detects when your readings start to drift, and tells you exactly what to focus on.
This is what tracking your biological age actually looks like.
Your body doesn't change overnight. It drifts.
You feel it before you can name it. The weight that won't move. The sleep that doesn't restore. The energy that drops earlier than it used to. These aren't random — they're connected. And they're measurable.
This is Health Drift — the slow, gradual shift in your body's internal balance that builds quietly over years. Your readings change before your symptoms do. BaseLine watches for it every day, so you don't have to wait until you feel it.
The weight won't shift — no matter what you do
When your glucose response starts drifting, your body stores more and burns less — even when you're eating well. The foods that used to work stop working. BaseLine shows you exactly what's driving it, so you stop guessing and start changing the thing that actually matters.
You sleep but never feel rested
Poor sleep and low energy aren't random — they follow a pattern in your data. Your morning glucose, your wake state, your blood pressure on the days you crash: BaseLine connects them all. Most people see the link within the first week and finally understand why some days feel impossible and others don't.
Your energy crashes and you don't know why
That 3pm slump. The foggy mornings. The days you're exhausted before you've done anything. These aren't lifestyle problems — they're data problems. Your blood pressure, glucose, and recovery signals all tell a story. BaseLine reads it for you and shows you which habits are draining your energy and which ones restore it.
BaseLine doesn't just track your numbers. It watches for the drift. The more you use it, the smarter it gets. When your readings are stable, the app eases off — telling you to test less often because your pattern is holding. But when it spots movement in the wrong direction, it increases attention: more readings, more frequently, with clear explanations of what's shifting and why.
And it doesn't just warn you — it tells you what to do about it. Every shift comes with a suggested action. Which habits to focus on. What's working. What isn't. BaseLine is an early-warning system that helps you stay ahead of the changes your body is always making — postponing what used to feel inevitable, and keeping you in control of the direction.

28 health insights you can't get anywhere else.
Most apps store your readings. BaseLine's engine calculates hidden markers from every reading you take — pulse pressure, cardiovascular load, insulin resistance proxies, and more — then connects them to your daily habits and adapts its coaching as your pattern builds.
Pulse Pressure
The gap between your systolic and diastolic readings reveals arterial stiffness — a longevity marker most people have never heard of. BaseLine calculates it automatically and tracks the trend over time.
Cardiovascular Load
A BP monitor tells you the pressure. It doesn't tell you how hard your heart is working to produce it. BaseLine calculates that effort — and shows you what's driving it up or bringing it down.
Habit Impact Ranking
Sixteen daily habits tracked and correlated to your actual readings. By the end of the 7-day challenge, BaseLine shows which habits moved the needle most — so you stop guessing and do what works.
Adaptive Coaching
The app moves through Baseline, Building, Maintenance, and Escalation phases. It learns your pattern, adjusts what it shows you, and writes a personalised coaching sentence every day based on your data.
Drift Detection
When the app spots a shift — a glucose creeping up, a BP zone change — it increases observation automatically. It knows when to watch more closely and tells you why. This is how you catch Health Drift before it catches you.
Cross-Metric Trends
Complete the 7-day challenge and unlock trends: best vs. worst days, a composite health score, and which habit combinations gave you the best readings. Everything connected in one view.
Not another health app.
An actual window in.
Real blood, not estimates
Smartwatches estimate glucose from light sensors. BaseLine uses a real finger-prick meter — the same method your GP uses. The difference in accuracy is everything.
What your body did overnight, not what you ate
Calorie trackers measure what goes in. BaseLine measures what your body does while you rest — your fasting glucose each morning tells you how well you recovered, how your body managed energy overnight, and whether your sleep actually did its job.
Calculated markers, not raw numbers
Most apps store readings and draw charts. BaseLine calculates pulse pressure, cardiovascular load, habit correlations, and adapts coaching — things no other consumer app does.
Patterns emerge that are invisible on day one.
One score. One verdict. No confusion.
The app tells you how you’re doing and why — in plain language, backed by your own data. Habits ranked by measured effect on your readings. By day 14, you’ll know exactly which habits matter most for your body — not someone else’s.
Four colours replace
every confusing number.
Every reading, every calculation, every trend — translated into a colour you understand at a glance. No googling, no confusion, no second-guessing.
Two features that make
a real difference.
Point. Shoot. Understand.
Take a photo of your meal and Jarvis reads the nutrient balance for you. No calorie counting. No logging. Just a clear picture of what you're putting in — and how it connects to your readings.
Calm, guided by your data.
Taken a reading and your BP is up? Breathe guides you through a calming exercise designed to bring it back down. No guesswork — just breathe, and let BaseLine show you what happens next in your own numbers.
Everything you need.
Ready to go.
CE-certified. Clinically validated.
A glucose meter and blood pressure monitor — the same type of equipment your GP surgery uses. Compact, accurate, and the app walks you through every step.
Glucose reading takes 5 seconds. BP monitor does two readings automatically. If you've never done a finger-prick before, don't worry — it's a tiny spring-loaded device. Most people stop noticing after the first couple of times.
Less guesswork. More control.
Finally know what your body is doing.
Everything you need.
Nothing you don't.

| Core tracking | ||
| Blood pressure & glucose▶ | ✓ | ✓ |
Most people gaining weight or struggling with energy have no idea their blood pressure and glucose are already shifting. Two readings a day — morning and evening — build a picture no GP appointment can match. You see the pattern. You stop guessing. | ||
| Four-zone colour system▶ | ✓ | ✓ |
Purple means optimal. Blue means balanced. Green means watch this. Amber means talk to someone. No jargon, no anxiety — just a colour that tells you instantly where you stand today versus where you stood last week. | ||
| MetaScore▶ | ✓ | ✓ |
One number, out of 12, built from your real readings. If you've been putting on weight, sleeping badly, or just feeling off without being able to explain why — your MetaScore shows you the direction your body is actually moving. Not what you feel. What is actually happening. | ||
| Health Drift detection▶ | ✓ | ✓ |
Drift is what happens before illness. Your readings shift slowly, week by week, in a direction you can't feel yet. By the time you notice something is wrong, it's been drifting for months. BaseLine catches it early — while it's still easy to change. | ||
| Trends▶ | ✓ | ✓ |
Your 7-day pattern view shows you whether this week is better or worse than last week. If you're trying to lose weight, sleep better, or feel younger — this is where you see whether what you're doing is actually working. | ||
| Practitioner card▶ | ✓ | ✓ |
When you're ready to go deeper, one tap links you to a certified practitioner who can see your real data and run a full metabolic session. You are never starting from scratch in that conversation — they already know your pattern. | ||
| Full intelligence | ||
| Metabolic Age▶ | ✕ | ✓ |
Your calendar age is a number. Your metabolic age is the truth. If your body is ageing faster than it should — from poor sleep, high glucose, elevated blood pressure — BaseLine shows you the gap. And more importantly, it shows you it closing as you improve. | ||
| Food Scan▶ | ✕ | ✓ |
Photograph your meal. Jarvis reads the macro balance and tells you how it fits your pattern. If your glucose is already running high, that plate of pasta looks very different than it would for someone else. This makes that visible. | ||
| Jarvis AI coaching▶ | ✕ | ✓ |
Jarvis reads your actual readings — not generic health tips. If your blood pressure spiked three mornings in a row, Jarvis noticed. If your fasting glucose is creeping up, Jarvis will tell you before you feel it. It talks to you like a person, not a dashboard. | ||
| Full MetaScore 0–48▶ | ✕ | ✓ |
After your first practitioner session, your MetaScore expands from 12 to 48. Blood markers, functional activity, and your daily readings combine into one complete picture of where your body is right now — and where it is heading. | ||
| Practitioner connection▶ | ✕ | ✓ |
Your practitioner sees your real data between sessions. They know your glucose pattern, your blood pressure trend, and your MetaScore before you walk in the door. No wasted time. No starting from scratch. Just a conversation that goes straight to what matters. | ||
