Overview

Cronometer is a food and nutrition tracker that pairs detailed nutrient logging with exercise, weight, and other health metrics. It suits people who want a closer view of what they eat than calorie totals alone provide. Basic covers core tracking, while its short reporting window makes Gold more useful for looking beyond the current week.

Key features

Food and nutrient tracking

Cronometer supports tracking up to 84 nutrients and other compounds. Its Basic plan draws on a database of more than 1 million lab-analyzed or verified foods, giving users a substantial foundation for detailed food records. Barcode scanning speeds up packaged-food entry, while manual logging and custom foods, meals, and recipes help cover items that are not scanned or need to be saved for reuse.

Basic includes reports and charts, but only for a 7-day window. That is enough for short-term checks; anyone trying to compare longer stretches will need Gold, which extends insights and charts to any time frame. Meal planning, progress tracking, and client goals broaden the feature set, though the central appeal remains personal food and nutrient tracking.

Health data, integrations, and privacy

Users can also track exercise, weight, and other health metrics. Listed integrations include Suunto, Keto-Mojo, Dexcom, WHOOP, Apple Health and Apple Watch, and Health Connect, useful for people whose health data already sits in those services or devices.

Cronometer describes safeguards including two-factor authentication, penetration testing, and privacy-by-design. Users can request deletion of their account and personal information, subject to stated exceptions. Support is available at support@cronometer.com.

Pricing

Basic is free and includes tracking up to 84 nutrients and other compounds, plus reports and charts limited to a 7-day window. It is the sensible starting point for users who want to log food without paying, but the brief reporting span constrains longer-term review.

Gold costs 10.99 USD per month, billed monthly, and adds ad-free tracking, more insights and charts over any time frame, and Crono Coach. It fits users who want longer-range charting and those who prefer an ad-free experience. Cronometer also offers a 30-day trial. The free plan retains the core nutrient tracking, so Gold's clearest reason to buy is its extended time frame and added features, not access to basic logging.

Cronometer Pro is dietary analysis software for health professionals, designed to simplify diet recall, data entry, and analysis. It may suit professional workflows better than a personal plan; pricing is custom.

Platforms

Cronometer is available on Android, iOS, and the web. That range suits users who want to log on a phone and review information in a browser, as well as those who prefer one platform over another.

Who it's for

Cronometer is a strong fit for people who want nutrient-level food tracking alongside exercise and health metrics, especially if its listed integrations match their existing devices or services. Basic makes it accessible for routine tracking, while Gold is the better choice for anyone who needs charts spanning more than a week. It is less compelling for someone interested only in a simple calorie tally or who does not need longer-term reporting.

Pros and cons

Pros: Tracks up to 84 nutrients and other compounds, with a database of over 1 million lab-analyzed or verified foods—useful for detailed nutrition monitoring.
Pros: Barcode scanning plus custom food, meal, and recipe creation gives users more than one way to handle food entry.
Pros: Exercise, weight, other health metrics, and a range of listed integrations bring related tracking into the same app.
Cons: Basic reports and charts stop at a 7-day window, limiting longer-term review unless users move to Gold.
Cons: Gold is an ongoing monthly cost for the longer time frames and ad-free tracking, which may not be worthwhile for users who need only basic logging.

Alternatives

Fitness Nutrition Software is a broader category to explore when comparing options.

CoachVana may be the better fit for coaches: its free plan includes every coaching feature for the first 3 active clients, and its Coach plan supports up to 5 clients for 29.00 USD per month.

MyFitnessPal is worth considering for food and exercise logging, recipes, measurements, and partner app connections; its free plan includes those features, while Premium (monthly) costs 19.99 USD per month.

Practice Better may suit practitioners seeking a client-management option, with a free Sprout plan for 3 active clients, 100 MB storage, and 1 practitioner license.

Tyzra is another freemium alternative for Android, iOS, and web.

Promealplan is a web-based alternative with a free plan limited to 3 meal plans total, 1 team seat, 7 days per plan, calorie-only plans, and 3 branded client apps.

Well&Co may suit users looking for client-facing nutrition and activity tracking, with its Starter plan including up to 5 clients, a day plan builder, in-app messaging, and basic analytics for 29.00 EUR per month.

Verdict

Choose Cronometer if detailed nutrient tracking, a large verified-food database, and related health metrics matter more than a simple calorie log. Its free Basic plan is a credible place to start, but users who want to examine patterns across longer periods will need Gold; those who do not need that reporting range can stay on Basic or look for a simpler tracker.
