Log what you ate
Search, scan a barcode, or fire a quick entry. Net and total carbs computed side by side, with the fiber and sugar-alcohol subtraction shown rather than hidden. Water too. Takes seconds, works offline.
Metabolic health tracking · keto · low-carb · GLP-1 · glucose-curious
Metabolism matters. So does everything that moves it.
What you eat, counted honestly. What the scale is doing over months, not days. How you train - and what is still recovering. The micronutrients you keep running short on. What your supplement stack actually adds. What your own blood glucose and ketones say. It all matters, and it all connects. metabomap is where you keep the receipts.
$39 for year one - first 250 paid accounts or through January 31, 2027, whichever comes first - then renews at the regular $49. Payments aren’t live yet; leaving your email puts you in line for a founding slot. No card, no charge.
How it works
Log the day. Read the trends. Keep the receipts.
Three steps, about a minute a day. No wearables required, no subscription required, no streak theater, no faith in packaging required. None of it is engineered to keep you scrolling - it’s engineered to keep a record.
Log the rest of the day
Fasting timers run themselves against your eating window - 24–72h extended fasts included. Workouts log in taps: 68 exercise types, structured reps, saved routines you re-run with one tap. Your supplement stack logs in a tap too. Steps, weight, and sleep arrive by Fitbit sync. And if you keep a blood meter, glucose and ketone readings take about ten seconds each.
Watch the record build
History charts and trends for every metric you track. Paired glucose and ketone readings become your GKI, with zone bands so the number means something at a glance. Look at your day whole instead of reconstructing it from memory - you stop guessing and start keeping receipts.
The home screen
Your day, drawn as a route.
The dotted line is the fasted morning. Each meal opens a response. The ring is now. metabomap's home screen draws today as one route - meals, readings, training and fasting on a single line you can read at a glance, with the number that matters most on top: net carbs left.
And one honesty rule carries the whole picture: readings stay dots. We never draw a curve we didn't measure.

The full kit
Everything a serious low-carb day needs. In one log.
Built keto-first, useful anywhere metabolic health matters - including if you’re on a GLP-1 and keeping an eye on protein. Every feature below is in the free tier today, with no ads.
Logging at the speed of eating
Fast search, barcode scanning, quick entries, water tracking. Built for the fact you’ll do this 1,400 times a year - logging you’ll actually still be doing in March.
Net and total carbs, together
Both numbers, every food, always - plus the fiber and sugar-alcohol lines they came from. Nothing subtracted where you can’t see it.
Glucose, ketones, GKI
Log readings, pair them, and get your Glucose Ketone Index with zone bands and charts. The metric serious keto runs on, computed natively.
Weight, on a timescale that tells the truth
Weight, body fat, and the tape-measure girths, charted over weeks and months instead of judged this morning. Daily noise is not a trend; the chart is what separates them.
Fasting that keeps itself
Fasting timers and protocols with daily eating windows and automatic start and end, plus 24–72h extended fasts when that’s your practice. Your fast tracks itself while you live your life.
Recipes with real numbers
Build a recipe and per-serving nutrition computes itself from USDA-backed data. No copying labels, no hand-waving portions.
Plan the week, shop once
A weekly meal planner that writes your grocery list. Check items off in the store - it works with zero bars of signal.
Movement, mapped to muscle
Sixty-eight exercise types with MET-based math, structured reps, 7-day charts - and a front-and-back body map showing what each muscle group is still recovering from, fading day by day, so you can see what is ready to train again. Save routines as circuits, log them in one tap. Steps and Fitbit sync keep energy-out next to energy-in, drawn on an actual body.
A challenge worth showing up for
Weekly community challenges and forums. Real people, disclosed accounts, no engagement theater.
Bring your own AI
Just tell Claude what you ate.
metabomap ships an MCP server, which means the assistant you already pay for can work your account directly - 42 tools across your diary, readings, fasting, training, supplements and meal plans. No copying numbers between apps. You talk, it logs.

The micronutrient layer · Premium
“Eat real food” stops being advice the moment you ask which mineral you’re short on.
Macros are the part everyone counts. The part that actually explains the headaches, the cramps and the flat training weeks is usually a mineral - and low-carb eating is famously an electrolyte problem wearing other clothes. Premium scores ten nutrients against FDA Daily Values, electrolytes first, on a daily %DV dashboard, with detail on every food, day and recipe.
See the gap, not a vibe
Sodium, potassium, magnesium and the rest, scored against Daily Values with a meets-or-below verdict. “I should probably get more magnesium” becomes a number with a date on it.
What the evidence says before you supplement
Each nutrient carries a plain-language read of the research, cited, with the upper limit that matters - including the ones where the ceiling applies to supplements and not to food. Written to help you decide, not to sell you a bottle.
Especially on a GLP-1
When appetite drops, protein and micronutrients are the first things to quietly slip. Smaller meals can still be complete ones - but only if someone is counting.
Who it’s for
Three kinds of people. One instinct: stop guessing, start measuring.
Different starting points, same move - log it honestly, run the math, watch the trend.
Keto and low-carb, for real
Net and total carbs both, GKI zones, fasting windows, recipes that don’t wreck the math. Built by people who know why maltitol is a betrayal.
On a GLP-1
When appetite shrinks, protein and micronutrients are the first things to quietly slip. metabomap keeps protein in view on every log, and Premium scores ten micronutrients against FDA Daily Values - electrolytes first, on a daily %DV dashboard - so smaller meals can still be complete ones, and you can see gaps while they’re still small.
Glucose-curious
You don’t need a diagnosis to want the data. Log your meals, log your readings, and watch your day whole - trends, charts, and your personal terrain building one honest entry at a time.
Label arithmetic
Labels make claims. We do the math.
The low-carb aisle runs on creative arithmetic - sugar alcohols subtracted wholesale, serving sizes written for a smaller appetite than yours. metabomap unpacks the claim: both carb counts on every food, the fiber and sugar-alcohol lines they came from, and portions at the amount you logged. And if you happen to own a blood meter, there’s a third column in the ledger.
The sugar-alcohol shell game
“2g net carbs” often means every gram of sugar alcohol was subtracted - including maltitol, which carries roughly half the glycemic punch of sugar. The label rounds it away and shows you the result. metabomap shows you the subtraction itself, so a 2g claim resting on 11g of maltitol looks like what it is. Our free calculator will re-run it per sweetener when you want the stricter number.
Serving-size sleight of hand
That per-serving number assumes you stopped at half a flatbread. The math on the package is negotiable; metabomap scales every number to the amount you actually logged - the whole flatbread, if that’s what happened.
Your n of 1
Two people eat the same food and their glucose writes two different stories. If you already own a blood meter, metabomap gives those readings a home: glucose and ketones logged in about ten seconds each, paired into a GKI with zone bands, charted over time - your meals and your readings in one log. Labels make claims. Meters file reports.

Our data
We’ll publish our error rate. Find another tracker that dares.
The dirty secret of this category is junk data - crowdsourced entries where the fiber is wrong, the sugar alcohols are missing, and your net-carb math quietly breaks. We took the opposite bet: a USDA-backed spine, provenance on every food row, user-created foods kept out of global search until verified, and a standing commitment to audit our own numbers and publish the results - errors included - in public. When we use AI to produce anything, it’s labeled. Accuracy over inventory, in writing, where you can check it.
Sourced, not scraped
USDA data as the spine. Every food carries its provenance, and search ranks trusted rows first.
Audited in public
Standing commitment: audit our data against real labels and publish the results - including the misses - with a corrections log. We’d rather be measurably imperfect than unverifiably confident.
Honest AI, disclosed AI
AI-generated content is labeled as AI-generated. Humans own the review. Getting caught pretending is fatal in a trust business, so we don’t pretend.
You are not the product
No ads in the app, and no ad-tech tracking pixels behind your login. Your health data is never sold, and never used to target advertising. The business model is boring on purpose: some people pay $49 a year, and that's it.
For the paywall refugees
Your last tracker moved the goalposts. Here’s our deal - in writing, dated today.
No commentary on the competition - you were there. So here’s today’s deal, in the present tense where it belongs: the complete daily practice - logging, barcode, net and total carbs, glucose and ketone entry, GKI, fasting, recipes, meal planning, grocery lists, community - is free today, with no ads and no card required. Premium is $49 a year or $9 a month for the depth layer: micronutrients with your supplements counted in, and Google sync. And two things will never be paid features: exporting your data and deleting your account.
The free tier is the trial
The complete daily practice is free today - barcode scanning, both carb counts, glucose and ketone logging, GKI, fasting, recipes, meal plans, grocery lists, community. No ads, no card required. We won’t promise the line never moves; we promise you’ll hear it from us before it does - not from a locked button. Judge the product by using the product.
One ladder, announced in advance
Premium is $49 a year or $9 a month - $39 for the first year of founding accounts, annual only - and that’s the whole ladder today: no Premium+, no add-on packs, no coins. If the price or the tiers ever change, you hear it from us first, in plain language - and there’s a 30-day money-back guarantee, once per account.
Cancel in two clicks
Online, from settings, instantly. If software makes you talk to someone to leave, it’s telling you what it thinks of you.
Lock $39 before it's $49
Payments open soon - so early actually pays. The first 250 paid accounts - or anyone in through January 31, 2027, whichever comes first - get Premium's first year for $39 instead of $49, renewing at the regular price. Leave your email to get in line for a founding slot: no card, no charge, no commitment until you decide - and the 30-day money-back guarantee applies when you do. Meanwhile, the free tier is open right now.
Fair questions
Do I need a glucose or ketone meter to use metabomap?
No. Everything on the food side - logging, barcode scanning, both carb counts with the subtraction shown, recipes, meal planning, fasting, exercise, community - works fully without one: a complete tracker, not a crippled one. If you do own a blood meter, readings take about ten seconds to enter, and pairing a glucose reading with a ketone reading computes your GKI, with zone bands so the number means something at a glance. If you don’t, nothing above is waiting on it. The math is the product; the meter is an instrument you’re welcome to bring.
Is metabomap really free?
The free tier is the complete daily practice: unlimited logging with search and barcode scanning, net and total carbs, blood glucose and ketone tracking with GKI, fasting timers, recipes, the weekly meal planner and grocery list, supplement logging, water, exercise, Fitbit sync, community, and articles - all in an app that installs to your home screen and keeps logging offline. No ads, and no card required. As the product grows the line between free and Premium can move; what we commit to is telling you before it does, never touching your ability to export your data or delete your account, and never selling what you log.
Does metabomap sync with my glucose or ketone meter?
Not today - and we’d rather tell you that plainly than imply a sync that doesn’t exist. You enter readings from any blood meter by hand; it takes about ten seconds each, and pairing a glucose reading with a ketone reading for GKI is built in. We only advertise what’s actually shipped.
What does Premium add?
Depth. Premium ($9/month, or $49/year - under a dollar a week) unlocks the micronutrient layer: ten nutrients scored against FDA Daily Values with electrolytes first, a daily %DV dashboard view, and micronutrient detail on every food, day, and recipe - with your supplement stack counted in the same math. It also adds Google sync, so steps, weight, and workouts arrive on their own. Low-carb eating is famously an electrolyte puzzle; Premium is the instrument panel for it.
What’s the founding offer?
The first 250 paid accounts - or anyone in through January 31, 2027, whichever comes first - pay $39 for their first year, renewing at the regular $49. Payments aren’t live yet, so joining the founding list costs an email address, not a card number, and puts you in line for a founding slot when checkout opens.
I’m on a GLP-1 medication. Is this for me?
Very much, and for a specific reason: when appetite drops, protein intake and micronutrients tend to quietly slip - it’s one of the most commonly reported struggles in GLP-1 communities. metabomap keeps protein in view on every log, and Premium scores ten micronutrients against FDA Daily Values, electrolytes first, on a daily %DV dashboard - so you can see what smaller meals are and aren’t delivering, and adjust while gaps are still small. It’s a tracking tool, not medical advice; your prescriber owns that lane.
How is this different from MyFitnessPal, Carb Manager, or Cronometer?
We compete on measurement, not inventory boasts. Net and total carbs computed together, with the fiber and sugar-alcohol subtraction shown on every food instead of resolved into one flattering number. GKI computed natively from your glucose and ketone readings, with zone bands. An exercise view that maps recovery onto a front-and-back muscle body map, fading each day, so you can see which groups are ready to train and which are still working through the last session. An MCP server that makes metabomap the first nutrition tracker your own AI assistant can use. A standing commitment to publish our label-audit error rate on the Our Data page. And a free tier that’s actually complete, with no ads and cancellation that takes two clicks.
What’s this about my AI assistant using it?
metabomap ships an MCP server with 42 tools, which makes it the first nutrition tracker your own AI assistant can use. Connect Claude - paste one URL, sign in, choose what it may touch - and it can log meals you describe, record a glucose and ketone pair and hand back your GKI, plan your week, and draft recipes grounded in USDA-backed data. It runs on the AI subscription you already have and it’s free on every metabomap plan. The full tool list, the setup steps, and a straight account of what it can and can’t reach are on the AI page.
Is metabomap medical advice?
No. metabomap is a wellness tool for seeing, tracking, and understanding your own logged data. It doesn’t diagnose, treat, or prevent anything, and it’s not a substitute for your clinician - bring your charts to them; that’s what the charts are for.
Stop guessing. Start keeping receipts.
Food, weight, training, fasting, micronutrients, your own readings - one log, free to start, no ads, no card, no countdown. Six months from now the record is the thing you’ll wish you’d started today.
