Detailed Description
Zero - Intermittent Fasting: Your Personalized Fasting Companion
Zero is a dedicated intermittent fasting tracker designed to simplify the practice of time-restricted eating. It helps users schedule, monitor, and optimize their fasting windows with a clean, intuitive interface. The app leverages scientific insights to support metabolic health, weight management, and long-term wellness.
Chapter 1: Function
Zero’s core functions center on tracking fasting periods with precision and minimal effort. Users start a fast with a single tap, and the app automatically counts down the remaining hours. It supports popular fasting schedules such as 16:8, 18:6, and 20:4, as well as custom durations. The app provides real-time notifications at key milestones like entering ketosis or autophagy, accompanied by educational tips. A dashboard displays daily, weekly, and monthly fast history, including total fasting time and streaks. Zero also integrates with Apple Health to sync activity data and provides a simple log for weighing in, allowing users to correlate fasting patterns with weight changes. The interface is deliberately uncluttered, focusing on the essential timer, history, and a minimal set of controls to reduce friction.
Chapter 2: Value
Zero delivers value by reducing the cognitive load and guesswork associated with intermittent fasting. Its primary advantage is automation: the app removes the need to manually calculate or remember fasting windows, which is especially beneficial for beginners. The milestone notifications serve an educational purpose, demystifying biological processes like ketosis and providing a sense of achievement. This positive reinforcement helps users adhere to their fasting plan consistently. For experienced fasters, Zero offers data transparency, enabling pattern recognition through historical logs. Users can identify which schedules yield the best results in terms of energy levels, weight, or sleep quality. The integration with Apple Health creates a holistic view of health metrics without requiring multiple apps. Another key advantage is its non-restrictive design; Zero does not prescribe a specific diet or calorie limit, making it adaptable to various eating philosophies like keto, plant-based, or Mediterranean. The app emphasizes habit formation over strict rules, encouraging gradual improvement. Its simplicity also means lower barriers to entry, as users can start tracking in seconds without a steep learning curve. Ultimately, Zero’s value lies in making the science of intermittent fasting actionable and sustainable for diverse individuals.
Chapter 3: Scenarios
Zero targets adults seeking a structured yet flexible approach to intermittent fasting for weight management, metabolic health, or longevity. Primary user groups include busy professionals who need a no-fuss timer to schedule fasting around work hours, individuals with prediabetes or insulin resistance looking to stabilize blood sugar, and fitness enthusiasts aiming to optimize body composition without extreme calorie restriction. Everyday use cases include tracking a 16-hour overnight fast from dinner to next-day lunch, setting a 20-hour fast for deeper autophagy on a weekly basis, and reviewing weekly fast streaks to maintain motivation. Another common scenario is using the app alongside a food journal to monitor how fasting affects hunger patterns and energy levels. The app also serves people who travel frequently and need to adjust fasting windows across time zones, as Zero can pause or restart a fast if needed. It is equally useful for beginners who require gentle guidance and for seasoned fasters who want precise data to refine their protocols.

Frequently Asked Questions
What is Zero and how does it track fasting?
Zero is an intermittent fasting app that tracks your fasting and eating windows. It uses a simple timer system, allowing you to start and stop fasts manually. The app calculates your fasting duration and syncs with Apple Health to log data. It supports popular fasting schedules like 16:8, 18:6, and 24-hour fasts, with optional reminders and a journal feature to note how you feel. No additional equipment is required beyond your iPhone or Apple Watch.
Is Zero free to use or does it require a subscription?
Zero offers a free version with basic features, including manual fasting tracking, cycle history, and simple reminders. A paid subscription (Zero Plus) unlocks advanced features like personalized fasting plans, health insights, weekly reports, and Apple Health deeper integration. The free tier is fully functional for casual users. There is no one-time purchase option; all paid features are subscription-based, with a free trial available for new subscribers.
Does Zero work on Android or only on iOS devices?
Zero is currently available exclusively for iOS devices, including iPhone, iPad, and Apple Watch. There is no official Android version or web app at this time. The app requires iOS 14.0 or later and works best with an internet connection for syncing data and subscription features. Users with older iOS versions cannot run the app. No Android support has been announced.
How accurate is Zero's fasting timer when I forget to stop it?
Zero relies entirely on manual start and stop actions. If you forget to stop a fast, the timer will continue running indefinitely, leading to inaccurate fasting records. The app does not auto-detect eating or activity. To correct this, you can edit past fasting sessions manually in the history log. There is no automatic pause or correction feature. Accuracy depends on user discipline and timely input.
Can I share my fasting data from Zero with my doctor or coach?
Zero can export limited data through Apple Health integration, which may allow sharing with health professionals if your doctor uses compatible health apps. There is no direct PDF or CSV export from Zero itself. For coaches, the app does not support real-time sharing or team features. Users must manually screenshot or summarize their fasting history. For detailed data sharing, consider third-party apps that sync with Apple Health.
