Only Fasting is a mobile app for intermittent fasting. Its core features include fasting timers, water intake tracking, meal and nutrition logging, progress statistics, meditation, and meal inspiration. It is explicitly positioned as a general health and information tool, not a medical device, and it does not provide medical advice, diagnosis, or treatment. Users must be at least 16 years old.
The product supports multiple fasting plans such as 16:8, 18:6, and 20:4, and can track hydration goals, streaks, health insights, and the calories βavoidedβ by resisting cravings. The AI component is mainly Nutrition Analysis: users can take photos of meals or describe meals in text to get instant estimates of calories and macronutrients. This helps lower the barrier to food logging, but the website does not disclose the model used, the source of its nutrition database, error margins, or accuracy rates. As a result, it is better treated as a rough reference rather than a basis for strict nutrition management.
The main content indicates that Only Fasting uses an in-app subscription model, with some premium features requiring payment. Specific subscription plans and prices are shown only inside the app; the website does not disclose any free quota, trial period, or feature differences between tiers. Payments are processed through the Apple App Store or Google Play Store. Subscriptions renew automatically, can be canceled in the corresponding store account settings, and refunds are handled according to the app storeβs policies.
The main strength is that its feature set is fairly complete for fasting use cases: timers, hydration tracking, meal estimation, meditation, and statistical insights form a closed loop. It supports more than 45 languages, giving it a relatively high level of internationalization. It also provides fairly clear explanations of medical risks and the boundaries of its responsibility. The downsides are limited transparency around key information, including exact pricing, AI model capabilities, data processing details, and Chinese-language support. AI-based nutrition estimates are inherently prone to error and should not replace medical advice, especially for people with diabetes, during pregnancy, or with eating disorders.
Only Fasting is suitable for general users who want a lightweight way to track intermittent fasting and hydration habits on their phone, while using AI to quickly estimate meal calories. It is not suitable for people who need medical supervision, precise nutrition prescriptions, or locally compliant health management. The main content does not disclose availability in mainland China, app store listing status, or payment availability, so these remain unknown. If it cannot be used, users may consider domestic alternatives that can be downloaded locally, support Chinese, and offer local payment options for fasting timers or food tracking.
