Zero Longevity is a mobile intermittent fasting and food-tracking app. Its page describes it as the “#1 Fasting & Protein App,” positioning it as a tool to help users lose fat, protect muscle, and build healthy habits. The product is available for download via the App Store and Google Play, with a free trial option provided.
Based on the captured page content, Zero is centered around fasting and nutrition management, including intermittent fasting tracking, food/nutrition logging, and protein-related management. Its value proposition is not simply calorie tracking; instead, it combines “fat loss” and “muscle preservation” as joint goals, making it suitable for users focused on weight management who do not want to sacrifice muscle mass.
However, from an AI application/tool perspective, the page does not disclose whether it uses AI models or offers capabilities such as personalized diet recommendations, smart reminders, automatic food recognition, or predictive analytics. As a result, its AI capabilities cannot be confirmed, nor is it possible to assess the model source, data training approach, or recommendation logic.
The page clearly includes “Download & Try for Free / Try for Free,” indicating that the app supports free downloads or a free trial. However, the main text does not provide the trial duration, feature limits of the free version, subscription pricing, billing cycle, or refund policy. Therefore, the business model can only be understood as an app with a free trial; specific pricing still needs to be confirmed through the app store or official website.
Its main advantage is very clear positioning: it targets intermittent fasting, protein management, and healthy habit formation, supports both iOS and Android, and is suitable for everyday mobile use. For people who want a low-barrier way to start tracking fasting and diet, the user flow should be relatively straightforward.
The limitations are also clear: the current page provides too little information. It does not disclose Chinese language support, privacy policies, health data handling practices, third-party device/API integrations, or the accuracy and medical boundaries of its recommendations. Users who need professional nutrition advice or medical-grade health management should still proceed with caution.
Zero is better suited for general users who are trying intermittent fasting, want to track diet and protein intake, and are aiming for fat loss and habit-building. Access from China cannot be determined based on the available content; app availability may depend on App Store/Google Play region settings and the network environment.
