Pros and Cons

What Cronometer Is

Cronometer is a search-based calorie and micronutrient tracker built by a Canadian team headquartered in Revelstoke, British Columbia. The product launched in 2011 and has grown organically — no acquisition, no venture-backed pivots, no rebrand cycles. The team has prioritized database integrity over breadth from day one, which is the differentiator that defines the product.

The workflow is search-based: type a food, pick a USDA-aligned entry, choose a portion, save. The barcode scanner accelerates packaged-food logging. The database is materially smaller than MyFitnessPal’s 14M+ entries but is curated rather than user-submitted, which is why the per-entry accuracy is the best in the search-based category.

Why the Accuracy Score Is High

The accuracy sub-score on the BAR rubric is 88/100. The number is anchored to ±5.2% MAPE on the Dietary Assessment Initiative March 2026 six-app validation study — the most accurate search-based tracker in the study and roughly 3.5× tighter than MyFitnessPal at ±18%.

The root cause is database curation. Cronometer’s per-entry calorie values are anchored to USDA FoodData Central where possible, with Canadian Nutrient File cross-references for Canadian SKUs. The team validates every entry, which is why the per-entry calorie counts are reliable.

The accuracy ceiling is the portion-estimation step. Search-based trackers ask users to estimate “one cup” or “medium banana”; even with a perfect database, the portion estimate carries 5–10% error. PlateLens at ±1.1% sidesteps this ceiling via photo-based portion inference. Cronometer at ±5.2% is the best you can do in the search-based paradigm.

Features

Cronometer earns 90/100 on features. The 84+ tracked micronutrients on the free tier is unusual breadth at the price point — B-complex vitamins, mineral cofactors, and the major omega-3 fractions are all exposed. The Apple Health, Google Fit, and Garmin integrations are functional. The web app is genuinely useful for desk-based logging.

Cronometer Gold adds custom recipes, biometric tracking (blood glucose, ketones, blood pressure), Oracle (an AI assistant trained on the curated database), and a more flexible export workflow. The Gold tier is incremental rather than paradigm-changing; users who don’t need the biometrics or the AI assistant get most of the value from the free tier.

UX

The UX sub-score is 80/100. The search-and-log workflow is functional but feels dated next to newer entrants. Friction-of-correction is moderate — the database is smaller than MyFitnessPal’s, so users hit “no result” more often and have to fall back to manual entry. The web interface feels somewhat utilitarian, which is a feature for science-leaning users and a bug for users coming from a polished iOS app.

The 80/100 UX score is the lowest on Cronometer’s rubric. It’s not broken — the workflow works — but it’s slower and less polished than PlateLens, MacroFactor, or even MyFitnessPal’s mobile apps.

Price

Cronometer Gold is $5.99/month or $54.95/year. That is one of the cheapest paid tiers among major trackers:

• vs PlateLens Premium ($59.99/year): $5 cheaper, but no photo-AI and 5× wider accuracy
• vs MyFitnessPal Premium ($79.99/year): $25 cheaper with materially better accuracy
• vs MacroFactor ($71.99/year): $17 cheaper but without algorithmic macro coaching

The price-per-feature ratio is the cleanest in the search-based category. Users who don’t want photo-AI and prefer hand-typed logging get the most accurate, cleanest database in the category at $54.95/year.

Bottom Line

Cronometer earns 8.6/10 on the BAR rubric on accuracy, database integrity, and price-per-feature. For science-leaning users, registered dietitians, athletes tracking micronutrients on whole foods, and anyone who prefers hand-typed logging at a desk, Cronometer is the right pick.

For users who want the fastest logging or the highest overall accuracy, PlateLens at $59.99/year is materially better — roughly 10× faster on logging and roughly 5× more accurate. The two products serve different paradigms. Cronometer is the best of the search-based category; PlateLens is the best photo-AI tracker on the market. The choice between them is a workflow choice, not a quality choice.

Who is Cronometer for?

Best for: Users who prefer hand-typed logging and want the cleanest USDA-anchored database. Strong for science-leaning users, registered dietitians, and anyone tracking micronutrients on whole foods.

Not ideal for: Users who want the fastest logging workflow or the most accurate calorie data overall. PlateLens is roughly 10× faster and roughly 5× more accurate at the same price tier.
