Aaron Davidson releases CRON-o-Meter as a free, open-source Java desktop app on SourceForge to track his CRON diet. The tool uses USDA nutritional data, has no monetization, no business entity, and no ads. It serves a niche community of calorie-restriction dieters with a commitment to data accuracy that will define the product's identity for the next two decades.
Cronometer transitions from open-source desktop app to a hosted web platform at cronometer.com, generating roughly $2,000/month in hosting fees by fall 2011. The company is formally incorporated as Cronometer Software Inc. The web version adds convenience but introduces basic hosting-fee monetization. Davidson runs the business part-time from Alberta with no employees, keeping overhead minimal.
Cronometer launches native mobile apps for iOS and Android, introducing a free ad-supported tier alongside a $2.99 one-time ad-free purchase. Davidson moves to Revelstoke and begins hiring his first employees as revenue reaches $28k/month. The mobile launch brings Cronometer's accurate NCCDB/USDA data to a mass-market audience but also introduces advertising as a monetization vector for the first time. Banner ads are modest at this stage.
Cronometer introduces the Gold subscription tier and Pro for healthcare professionals, shifting from one-time purchase to recurring revenue. Gold gates features like custom charts, fasting timer, and recipe sharing behind $49.99/year. The Pro tier launches with HIPAA compliance for dietitians. The company surpasses 1 million users and reaches $40k/month revenue while remaining entirely bootstrapped. Ads become more prominent on the free tier but are not yet the aggressive full-screen video variety.
Cronometer's user base grows past 8 million as partnerships with WHOOP, Dexcom, and Practice Better expand the platform's health data ecosystem. A controversial November 2022 UI redesign draws widespread backlash over reduced information density and poor desktop usability. The free-tier ad experience begins worsening with ads blocking navigation elements. Feature stratification deepens as Gold-exclusive features like recipe importer and fasting timer widen the gap between paid and free tiers.
Cronometer's free tier has degraded significantly with intrusive full-screen video ads that hijack the app during food logging. Gold pricing reached $59.99/year with AI-powered features like Photo Logging and CGM charts locked behind the paywall. The company surpassed 13 million users and roughly $1 million/month in revenue while remaining bootstrapped and founder-led. Data sharing with ad networks and growing feature stratification mark a worsening trajectory despite continued product investment.
Alternatives
Data-driven nutrition tracker with adaptive metabolism algorithms that adjust macro targets based on your actual weigh-ins and intake. No free tier ($71.99/year), but the AI-powered coaching and user-friendly interface make it the best option for serious fitness enthusiasts. Moderate switch — you can export Cronometer data as CSV.
Simpler calorie-focused tracker with an intuitive interface, ideal for weight loss goals rather than micronutrient optimization. Premium costs $39.99/year, comparable to Cronometer Gold. Less detailed nutrient tracking but easier to use for casual users. Easy switch.
The most widely used calorie tracker with 250M+ downloads and the largest food database (18M+ items). Free tier is more generous than Cronometer's ad-heavy version, though micronutrient tracking is far less detailed. Scored 53 here (Severely Enshittified) due to its own paywalling and data practices. Easy switch.

Timeline (30 events)
Aaron Davidson creates CRON-o-Meter open-source desktop app
Software developer Aaron Davidson, experimenting with the CRON diet (Calorie Restriction with Optimal Nutrition) at the University of Alberta, creates an open-source Java desktop application for tracking nutrition. The app is released under the Common Public License on SourceForge. It uses USDA nutritional data to track detailed micronutrient intake, addressing a gap in existing tools.
Cronometer web app launches at cronometer.com
Davidson launches a web-based version of the nutrition tracker at cronometer.com, transitioning from the open-source desktop app to a hosted platform. By fall 2011, the web app generates roughly $2,000/month in revenue from hosting fees, establishing Cronometer as a viable side business. The web version retains the NCCDB and USDA data sources that differentiate it from competitors.
Cronometer launches iOS mobile app
Cronometer releases its first native iOS mobile app, expanding beyond the web platform to reach smartphone users. The app includes a free ad-supported tier alongside a $2.99 one-time purchase for an ad-free version. Davidson moves to Revelstoke, BC and begins transitioning Cronometer from a side project to his primary business, hiring his first full-time employees at approximately $28k/month revenue.
Davidson goes full-time on Cronometer at $40k/month revenue
With revenue reaching $40,000/month and a small team of 4 full-time and 2 part-time staff, Aaron Davidson transitions to working on Cronometer full-time. The company has grown entirely through organic word-of-mouth over 12 years with no venture capital or external funding. Revenue had grown from $3,500/month in 2012 to $6k in 2013, $12k in 2014, $18k in 2015, and $28k in 2016.
Cronometer Gold subscription tier introduced
Cronometer launches its Gold subscription tier, offering premium features like custom charts, custom biometrics, and an ad-free experience for a recurring fee. This marks the transition from the one-time $2.99 ad-free purchase model to a recurring subscription model. Free users retain core tracking functionality but see ads. The app surpasses 1 million registered users around this time.
Cronometer Pro launched for healthcare professionals
Cronometer introduces its Pro tier targeting dietitians, nutritionists, hospitals, and research institutions. The platform provides HIPAA-compliant client management with encrypted messaging, nutrition reports, and multi-client diary monitoring. Pro clients receive complimentary Gold access for their patients. Pricing starts at $39.99/month for individual practitioners with 10 included client seats.
Columbia Basin Trust supports Cronometer's Revelstoke expansion
Cronometer secures a business loan through Columbia Basin Trust's Impact Investment Fund after traditional banks declined funding, enabling the company to hire additional staff in Revelstoke. The company also obtains funding for an intern through the Trust's Career Internship Program. By this point Cronometer employs 17 people locally and 5 remotely, growing from a one-person operation to a meaningful local employer.
Practice Better integration launched for nutrition professionals
Cronometer integrates with Practice Better, a practice management platform for health professionals, allowing automatic syncing of food and biometric data to client journals. The integration pulls 3 months of historical data on connection and updates in near real-time. This expands Cronometer's B2B ecosystem beyond its own Pro platform, supporting open interoperability with third-party practice management tools.
Cronometer launches Apple Watch companion app
Cronometer releases an Apple Watch app providing quick-glance access to daily energy intake, remaining energy targets, nutrition scores, and highlighted nutrients. The wearable expansion brings nutrition tracking to the wrist, complementing existing Apple Health integration for exercise and biometric data syncing.
Major UI redesign draws widespread user backlash
Cronometer rolls out a complete visual redesign across iOS, Android, and web with new brand colors, fonts, and layout. Community forums flood with complaints about reduced information density, excessive scrolling, gray night mode with low contrast, and a design that feels 'clunky and childish.' Users on desktop criticize the mobile-first approach that wastes screen space. The company acknowledges feedback and works on increasing information density but does not revert the changes.
Dexcom CGM integration launches for diabetes management
Cronometer announces integration with Dexcom continuous glucose monitors (G6 and G7), allowing users in the US, Canada, UK, Ireland, and Australia to import real-time glucose data. Gold subscribers can overlay glucose readings against nutrient intake using Custom Charts, enabling diabetics and health-conscious users to see how specific foods affect blood sugar. The integration targets Cronometer's existing diabetes-management user base.
WHOOP partnership adds fitness recovery and strain tracking
Cronometer partners with WHOOP, the human performance wearable company, to allow users to import sleep stages, recovery scores, resting heart rate, and skin temperature data. Gold subscribers can chart WHOOP metrics against nutrient intake to identify correlations between diet and recovery. The partnership deepens Cronometer's wearable ecosystem alongside existing Fitbit, Garmin, and Oura integrations.
Cronometer surpasses 8 million registered users
Cronometer announces crossing 8 million users worldwide, demonstrating continued organic growth in the competitive nutrition tracking market. The milestone reflects the app's differentiation through lab-verified nutritional data from NCCDB and USDA sources, which increasingly attracts users dissatisfied with MyFitnessPal's user-submitted data accuracy.
Canadian Food Innovation Network awards $47K AI grant
Cronometer receives a $47,378 grant from the Canadian Food Innovation Network (CFIN) through its Innovation Booster Program to develop an AI-powered Food Suggestions feature. The grant is one of eight foodtech projects sharing $654,417 in total funding. This represents Cronometer's only known external funding beyond the Columbia Basin Trust business loan, reinforcing its bootstrapped growth model.
Recipe Importer algorithm retrained to 92% ingredient matching
Cronometer retrains the Gold-exclusive Recipe Importer algorithm, improving its ingredient matching success rate by 10% to 92% overall. The feature allows Gold subscribers to paste a URL from a cooking website and automatically generate a Custom Recipe with ingredients, measurements, and nutritional data. Free users must enter ingredients manually, widening the feature gap between tiers.
Cronometer reaches 9 million users worldwide
Five months after hitting 8 million, Cronometer announces surpassing 9 million registered users globally, adding approximately 1 million users in a 5-month span. The accelerating growth rate reflects broader consumer interest in nutrition tracking and Cronometer's increasing visibility through partnerships with WHOOP and Dexcom.
Health Connect replaces Google Fit integration on Android
Cronometer transitions Android users from Google Fit to Google's Health Connect platform for syncing health data across devices. Health Connect acts as a centralized health data hub replacing Samsung Health and Google Fit integrations. The change follows Google's broader deprecation of Google Fit in favor of Health Connect, and Cronometer's compliance maintains interoperability standards.
Cronometer reaches 10 million users milestone
Cronometer crosses 10 million registered users worldwide, adding 1 million users in approximately 5 months since hitting 9 million in February 2024. The company celebrates with a 30% discount on all plans through July 30, 2024. The growth acceleration coincides with increasing user migration from MyFitnessPal, where 64% of Cronometer users reportedly tried MFP before switching.
Water tracking feature launched for all users
Cronometer introduces a dedicated Water Tracking widget available to all users (not Gold-gated), with a default goal of 6 cups for female and 8 cups for male users. The feature includes an iOS Home Screen Widget for one-tap logging without opening the app. This represents a rare recent example of a feature launching free for all tiers rather than as a Gold exclusive.
AI-powered Food Suggestions feature launches for Gold users
Cronometer releases its AI-powered Food Suggestions feature, funded by the 2023 CFIN grant, exclusively for Gold subscribers. The feature analyzes nutritional targets, dietary preferences, recently logged foods, and restrictions to recommend meals that fill nutrient gaps. It later expands to the web version in November 2024. The AI-only access for paying users adds mild algorithmic opacity to an otherwise transparent platform.
Cronometer revenue reaches $3.8M with 3.5M paying customers
Business intelligence platform Latka reports Cronometer Software generating $3.8 million in annual revenue, up from $3.2 million and $1.9 million in prior years. The company serves 3.5 million customers while maintaining its bootstrapped, no-VC model. Revenue growth has accelerated from $40k/month in 2017 to approximately $316k/month by late 2024.
Strava integration removed due to API terms conflict
Cronometer disconnects all Strava-linked accounts after Strava updates its API terms to prohibit third-party use of data for AI model training. Despite negotiations, Cronometer is informed it no longer meets Strava's requirements. Existing synced data remains in user accounts, but future automatic syncing is permanently disabled. Users must switch to alternative exercise tracking integrations like Garmin or Apple Health.
Ad-free Android app discontinued from Google Play Store
Cronometer discontinues the $2.99 one-time-purchase ad-free Android app from the Google Play Store, leaving the free ad-supported version as the only option for new Android users who don't subscribe to Gold. Users who previously purchased the paid app retain ad-free access, but new users must either tolerate full-screen video ads or subscribe to Gold at $59.99/year. This eliminates the affordable middle option between free-with-ads and the full subscription.
Free tier data lookback restricted to 7 days
Cronometer limits free-tier users to viewing only 7 days of historical nutrition data in reports and charts, down from previously longer lookback periods. Gold subscribers retain unlimited historical data access. The restriction means free users cannot track trends over weeks or months, significantly reducing the utility of long-term nutrition tracking without a subscription. Thousands of free users hit the 7-day data wall weekly.
Full-screen video ads escalate on free tier
User complaints about intrusive advertising on Cronometer's free tier reach a critical mass, with forum posts and app store reviews describing full-screen video ads lasting 15-30 seconds that 'hijack the app,' block bottom navigation buttons, and interrupt mid-meal logging. Some ads play audio. A bug in version 4.39.3 caused excessive ad frequency, which Cronometer acknowledged and patched. Users report feeling 'bullied' into paying for Gold just to regain control of the app.
Diary Groups feature unlocked for all users
Cronometer makes Diary Groups, previously a Gold-exclusive feature, available to all users for free. The feature allows users to organize food diary entries by meal categories with custom labels. This represents a counter-trend to the general paywall expansion, suggesting selective unbundling to maintain free-tier usability.
Cronometer updates Terms of Service
Cronometer publishes updated Terms of Service dated February 12, 2025, incorporating changes to subscription terms including a shift from twelve-month to six-month policy periods. Auto-renewal remains the default for Gold subscriptions, with cancellation available through account settings or email. The updated terms reflect the company's evolving monetization approach.
CGM chart feature launches with expanded glucose tracking
Cronometer announces enhanced CGM integration enabling seamless continuous glucose monitor data visualization. Gold subscribers can overlay glucose readings against specific nutrient intake on custom charts, while the CGM Chart provides detailed blood sugar trend analysis. The feature builds on the January 2023 Dexcom integration and expands glucose monitoring capabilities to a broader audience of health-conscious users.
Privacy policy updated to align with new regional laws
Cronometer revises its Privacy Policy to better align with recently enacted privacy laws in the regions it serves, including updated GDPR, CCPA, and Canadian privacy regulations. The policy further details user rights and contact points. The company continues to maintain it does not sell personal data but reserves the right to share aggregated or de-identified information for marketing, advertising, and research purposes.
AI Photo Logging launches as Gold-exclusive feature
Cronometer releases Photo Logging, letting Gold subscribers snap meal photos for AI-powered food identification matched against the lab-verified database. The feature identifies ingredients and estimates portions, with matching time reduced from 10-15 seconds to 5-7.5 seconds in later updates. By this point Cronometer has surpassed 13 million users. The Gold-only gating of the most user-friendly logging method increases pressure on free users to upgrade.
