Cronometer Review UK (2026)
The nutrition tracker serious about micronutrients - tracking 84 vitamins and minerals, not just calories.
What is Cronometer?
Cronometer is a Canadian nutrition tracking app that focuses on accuracy and micronutrient detail. While most apps stop at calories and macros, Cronometer tracks 84 nutrients including individual vitamins, minerals, amino acids, and more.
The app was built for people who take nutrition seriously - whether that's managing a health condition, optimising athletic performance, or following a specific diet like keto or vegan. It's particularly popular with the biohacking community and those interested in detailed nutrient tracking.
What Makes Cronometer Different
Most food databases are user-submitted and full of errors. Cronometer uses lab-analysed data from:
- NCCDB: Nutrition Coordinating Center Database (77 nutrients per food)
- USDA: US Department of Agriculture food database
- Nutritionix: UK and Ireland branded foods (recently added)
All user submissions are verified by Cronometer staff before being added - no random entries with made-up data.
Key Features
- 84 micronutrients: Track vitamins (A, B1-12, C, D, E, K), minerals (iron, zinc, magnesium, etc.), amino acids, and more
- Lab-verified database: 1.1M+ foods with staff-checked accuracy
- Macro tracking: Full calorie, protein, carb, fat, and fibre tracking
- Custom targets: Set your own nutrient goals or use calculated recommendations
- Nutrition scores: Visual dashboard showing where you're hitting targets
- Barcode scanner: Works for UK products (improving but not comprehensive)
- Biometric tracking: Log weight, blood pressure, blood glucose, and custom metrics
- Recipe importer: Import recipes from URLs and calculate nutrition
UK Food Database
Historically, Cronometer has been US-centric. However, they've recently integrated Nutritionix, which includes UK and Ireland branded foods. This means better coverage for UK supermarket products when scanning barcodes.
That said, coverage isn't perfect. Some UK users report needing to add foods manually or finding that barcode scans show American equivalents. Generic whole foods (chicken breast, broccoli, oats) work well, but branded UK products are hit-or-miss.
Cronometer Pricing UK
Cronometer offers a genuinely useful free tier, with Gold subscription adding convenience features:
Cronometer UK Pricing (January 2026)
| Plan | Price | What's Included |
|---|---|---|
| Free | £0 | Full nutrient tracking, custom targets, basic features |
| Gold (Monthly) | ~£7-8/month | Ad-free, charts, fasting timer, recipe importer, print reports |
| Gold (Annual) | ~£50-55/year | Same as monthly, ~30% savings |
Note: Pricing shown in USD on website. Actual GBP varies with exchange rate.
Is Gold Worth It?
The free version covers the core tracking. Gold adds:
- Ad-free experience
- Detailed charts and trend analysis
- AI food suggestions
- Fasting timer
- Recipe importer from URLs
- Print professional PDF reports
If you're a casual tracker, free is fine. If you're serious about nutrition analysis or following a specific protocol, Gold is reasonably priced.

What Real Users Say
Cronometer has a 4.7/5 rating on the App Store and strong reviews from the nutrition community:
"Cronometer is miles ahead of competitors for accuracy. The micronutrient tracking is incredible - I can see exactly where my diet is lacking. Worth every penny of Gold subscription." - App Store review
"Database of food is inadequate and inaccurate for UK users. Had to add many items manually." - UK Trustpilot review
Common praise: Accuracy, micronutrient detail, clean design, professional-grade tracking
Common complaints: UK database gaps, learning curve, some find it overwhelming
Who Cronometer Is Best For
Micronutrient Optimisers
If you want to know your vitamin D, iron, magnesium, and zinc intake, Cronometer is unmatched.
Keto/Low-Carb Dieters
Popular with the keto community for tracking net carbs and ensuring adequate electrolytes.
Vegans/Vegetarians
Essential for tracking B12, iron, zinc and other nutrients that need attention on plant-based diets.
Data-Driven Trackers
If you want charts, trends, and detailed analysis rather than gamification, Cronometer delivers.
Who Should Look Elsewhere
- Casual trackers: If you just want simple calorie counting, Cronometer may be overkill
- UK branded food trackers: If you eat lots of packaged UK foods, database coverage is still patchy
- Social motivation seekers: No friends, challenges, or community features
- Meal planners: Doesn't include meal plans or recipes like some competitors
The Bottom Line
Cronometer is the serious tracker's tracker. If you care about micronutrients - whether you're managing a health condition, optimising performance, or following a specific diet - it provides detail that other apps simply don't.
The UK database has improved with Nutritionix integration, but it's still not as comprehensive as US coverage. Expect to add some foods manually if you eat lots of UK branded products.
Our verdict: Worth trying if you want more than basic calorie counting. The free tier gives you the full micronutrient tracking experience.
