What Zero does
Zero Longevity Science, Inc. operates Zero, a mobile health and fitness application focused on intermittent fasting tracking and nutrition guidance. The app serves health-conscious consumers seeking weight management, habit formation, and improved nutrition through a combination of real-time fasting timers (supporting 16:8, 20:4, and 36-hour protocols), AI-powered photo and text-based meal logging, a proprietary Protein Score that converts daily calorie-protein balance into a single guidance metric, and hydration tracking. Core technology combines computer vision for food recognition, natural language processing for text-based meal input, and a personalization engine that surfaces pattern-based insights over time. The platform reports millions of members with documented individual weight-loss outcomes.
The business operates on a freemium model distributed through the Apple App Store and Google Play Store, with a free tier offering core fasting and tracking features and a premium subscription unlocking advanced capabilities. Zero is incorporated in the United States, headquartered in New York, and serves a global user base through mobile app marketplaces without geographic restrictions. Marketing relies heavily on earned media across major health and lifestyle publications (Men's Health, Fortune, Fast Company, Women's Health, Good Housekeeping), an affiliate program, content marketing, and organic social media channels — a product-led, low-CAC acquisition model.
The company has raised approximately $4 million in disclosed seed-stage funding from True Ventures, Trinity Ventures, SV Angel, and Audrey Capital, with the most recent round in August 2019. Zero is led by founder Kevin Rose and CEO Mike Maser, with Nicholas Robinson serving as Chief Business Officer. The team is small (1-10 employees), indicating a lean operating model that depends on product and content rather than enterprise sales infrastructure, and there is no evidence of a parent company, institutional growth capital, or M&A activity.

Zero competitors and assessment
Company assessmentBroad incumbents
- Apple Health: OS-level health platform that increasingly embeds fasting timers, nutrition logging, and hydration tracking directly into iOS — a major competitive threat to Zero's standalone positioning.
- Samsung Health: Platform-level health and fitness ecosystem with meal tracking, fasting, and water tracking features built in — competing with Zero on distribution and integrated user experience.
Direct peers
- MyFitnessPal: The dominant food/nutrition tracking app with calorie and macro logging, similar to Zero's AI meal tracking feature. Direct competitor in the consumer nutrition-tracking category with a comparable freemium business model.
- Cronometer: Detailed nutrition tracking app with comprehensive macro/micronutrient analysis, competing with Zero's Protein Score and meal tracking capabilities in the same nutrition-tracking category.
- Noom: Subscription-based weight management and behavior change platform targeting the same weight loss and habit-formation segments Zero serves. Competes directly for the same health-conscious consumer wallet.
- BetterMe: Health, fitness, and weight loss app with meal tracking and fasting features, serving the same consumer weight-management segment with a broader fitness/coaching portfolio.
- LifeSum: Health and nutrition tracking app combining meal logging, fasting, and weight management — directly overlapping with Zero's feature set and target health-conscious consumer segment.
- Yazio: Fasting and food tracking app with intermittent fasting protocols and meal logging, the most direct European competitor to Zero's fasting timer and nutrition tracking combination.
Emerging players
- Simple (fasting app): Intermittent fasting-focused app that has rapidly grown as a Zero alternative, particularly popular among beginner fasting audiences — directly competing for Zero's primary beginner segment.
Others
- Headspace: Leading consumer wellness subscription app, not a direct nutrition competitor but a comparable consumer health brand targeting the same wellness-conscious consumer with a freemium subscription model.
