Core features

Everything built,
ready on launch.

Every feature below is implemented and ready. carbIQ launches with the full platform — not a stripped-down MVP.

Personal Insights engine

Detects correlations between your glucose and specific foods, sleep, activity, and stress. Confidence-rated insights built on your data — not population averages.

✓ Built

850,000+* food database

4,200 clinically verified GI entries. 845,800+ ML-estimated entries clearly labelled. GI, GL, macros, and your personal response layer — all in one search.

✓ Built

Health overlays

Plot any two health streams against each other. Sleep vs glucose, steps vs blood pressure — with Pearson r correlation scores surfacing the hidden relationships in your data.

✓ Built

Barcode scanner

Point at any packaged food and log it instantly. GI estimation, full macros, and your personal glucose prediction on every scan.

✓ Built

Apple Health sync

Syncs activity, sleep, heart rate, and weight data from Apple Health. Coming at launch alongside iOS — no manual entry required for wearable data.

Launching soon

Record sharing

Share glucose logs, correlation views, and insight exports (PDF, JSON, CSV) directly with your GP, dietitian, or specialist.

✓ Built

Simple Mode

One focus per day. Plain English. Designed for users who want clinical insight without complexity — toggle between Simple and Full mode any time.

✓ Built

Privacy-first design

End-to-end encrypted. Zero data selling. Full data portability. Your health data belongs to you — not advertisers, not data brokers.

✓ Built

Recipe import

Every carbIQ recipe has a unique CIQ-XXXX code. Paste it in-app to import the full recipe, GI breakdown, and macro data instantly.

✓ Built
Core USP — Overlays

See the connections
no other app reveals.

Most health apps show you one stream at a time. carbIQ lets you overlay any two health streams and calculates the statistical correlation between them. This is the feature that turns data into understanding.

Any two streams

Glucose vs sleep, steps vs blood pressure, mood vs fasting levels — any combination from your 10 health streams.

Pearson r correlation score

Statistical strength and direction — strong, weak, positive, negative — all surfaced clearly.

Stress as a confound

High-stress days distort glucose data. carbIQ detects and excludes these so your food correlations stay accurate.

Privacy-first

Your data belongs
to you. Full stop.

carbIQ is built on a privacy-first foundation. Your personal health data is stored in your private encrypted account, never sold, never used for advertising, and never shared without your explicit consent.

End-to-end encrypted

All personal health data is encrypted at rest and in transit. Only you can access your full data profile.

Zero data selling — ever

carbIQ will never sell your personal health data to third parties, advertisers, or data brokers. No exceptions.

Consent-driven

Every data permission is opt-in, clearly explained, and revocable at any time. No dark patterns or buried consent.

Full portability

Export your entire health history as JSON, CSV, or PDF any time. Full account deletion with one tap.

Data for good

Helping understand what's really driving metabolic illness.

With your explicit opt-in consent, carbIQ contributes anonymised, de-identified data to population-level health research. No names, no identifiers — just aggregated patterns that help researchers and public health bodies understand what foods, behaviours, and environments are driving blood sugar issues across populations.

Always opt-in. Never assumed.

Always opt-in, never assumed

Anonymous data contribution is strictly opt-in. Users who decline participate in nothing.

Fully anonymised & aggregated

Stripped of all personal identifiers before leaving the device. Only population patterns are shared — never individual records.

Supporting real-world research

Feeds public health initiatives to understand which foods, behaviours, and environments drive blood sugar issues at a population level.

Transparent & auditable

Users can see exactly what categories of data are contributed and withdraw any time. Annual transparency report published.

"I'd been guessing about food for years. The database changed everything — I can scan anything, see the GI and GL immediately, and know exactly what I'm putting in my body."

FAQ

Questions
answered.

What exactly is carbIQ?

carbIQ is a personal metabolic health app for people managing diabetes, pre-diabetes, or blood glucose conditions. It combines an 850,000+ food database (with glycaemic index and glycaemic load data) with a personal Insights engine that analyses up to 10 health streams to surface the specific correlations in your data — not population averages.

Who is carbIQ for?

carbIQ is built for people with Type 1 diabetes, Type 2 diabetes, pre-diabetes, insulin resistance, PCOS, or anyone actively managing their blood glucose levels. It's also used by carers, dietitians, and anyone who simply wants a deeper understanding of how food and lifestyle affect their metabolic health.

Is carbIQ free?

Yes — carbIQ has a free tier that includes blood glucose logging, basic food and meal logging, activity tracking, and basic 14-day insights. There's no time limit on the free tier. Premium unlocks the full Insights engine, all 10 health streams, barcode scanner, meal planner, record sharing, and insight exports. Premium is £3.99/month or £27.99/year. All plans include a 3-day fully unlocked free trial — no card required.

What is the GI database and how accurate is it?

Our database contains 850,000+ foods. 4,200 of those have clinically verified glycaemic index values sourced from peer-reviewed research. The remaining 845,800+ foods use our ML model to estimate GI from macronutrient composition — these are clearly labelled as estimated in-app so you always know what you're looking at.

What is the Overlays feature?

Overlays let you plot any two health streams against each other — for example, your sleep duration vs your fasting blood glucose levels, or your daily steps vs your blood pressure. carbIQ calculates the Pearson correlation coefficient (r) between them to show you the statistical strength and direction of the relationship. This is carbIQ's core USP — no other consumer health app surfaces this kind of cross-stream correlation analysis.

How does Simple Mode work?

Simple Mode strips carbIQ back to the essentials — one health focus per day, shown in plain English. Instead of dashboards full of numbers, you get a single clear message: "Your glucose spikes most after breakfast on weekdays." You can toggle between Simple Mode and Full Mode at any time. Your underlying data is identical — only the presentation changes. Simple Mode is particularly popular with older users and those new to health tracking.

How does carbIQ handle my personal health data?

Your personal health data is stored in your private encrypted account. It is never sold to third parties, never used for advertising, and never shared without your explicit consent. You can export your full data history (JSON, CSV, or PDF) or request complete account deletion at any time. carbIQ is built privacy-first by design — not as a legal afterthought.

What is the anonymous data programme?

With your explicit opt-in consent, carbIQ can contribute fully anonymised and de-identified aggregated data to population-level health research. This helps public health bodies and researchers understand what foods, behaviours, and environments are driving metabolic illness at a population level. This is strictly opt-in — users who do not opt in contribute nothing. Participants can withdraw at any time and view exactly what data categories are being contributed.

Does carbIQ work with Apple Health?

Apple Health sync is launching alongside the iOS app. It will import activity, sleep, heart rate, and weight data automatically from Apple Health — no manual entry required for data already collected by your iPhone or Apple Watch. Apple Watch and broader wearable integrations are also on the near-term roadmap.

When does carbIQ launch and what platforms will it be on?

carbIQ is launching on iOS and Android. A web dashboard and Apple Watch app are on the near-term roadmap. Join the waitlist to be notified the moment we go live and to get priority early access.
