Dalia is a personal health management app from StethoAI LLC, positioned somewhat like “WHOOP meets MyFitnessPal.” It emphasizes using only a phone camera—without a wearable—to track recovery, HRV, stress, and heart rate, while also logging meals via photos. The company also sells hardware such as the StethoAI stethoscope and DaliaSense blood pressure monitor, but the app itself is marketed around the idea that “one phone is enough to get started.”
Its VitalTouch feature asks users to cover the rear camera with a finger, then uses PPG signals to generate heart rate, HRV, stress, energy, and respiratory rate readings in about 30 seconds, while saving long-term trends. On the nutrition side, it supports photo-based meal recognition to estimate ingredients, portions, calories, macronutrients, vitamins, and minerals. The AI Health Coach answers questions based on context such as HRV, stress, diet, and sleep, creates daily briefings, and identifies patterns across data sources. The site says it works with leading AI companies, but does not disclose specific models, validation data, or accuracy figures.
The product is marked as free to start, and VitalTouch is included with Dalia for free, but the limits of the free plan are not explained. Paid tiers are Smart Nutrition at $2.99/month, 360 Health at $4.99/month, and AI Health Coach at $7.99/month. Hardware is sold separately, and all purchases are non-refundable. Payments support Visa, Mastercard, American Express, and PayPal, with billing in USD. For integrations, it supports Apple Health, Apple Watch, Bluetooth blood pressure monitors, digital stethoscopes, and pulse oximeters; no open API documentation was found.
The main advantages are that it can provide basic recovery and stress tracking without a wristband, photo-based food logging is easier than traditional manual entry, and it can combine vital signs, diet, sleep, and other data for analysis by an AI coach. Subscription pricing is also relatively low. The limitations are that it is explicitly not a medical device, the health coach does not constitute medical advice, and StethoAI analysis is not a definitive diagnosis. At the same time, there is limited public evidence around algorithm transparency, clinical calibration scope, and the objective accuracy of meal recognition. It is suitable for general users interested in lifestyle management, fitness recovery, and food logging, but not for people who would rely on it for diagnosis or treatment decisions.
The site does not provide information on availability in China, a Chinese-language interface, or local payment options. Data hosting and processing are in the United States, so cross-border privacy implications should be assessed independently. Users in China may also face issues with app availability, network connectivity, and PayPal/international card payments. If a Chinese-language ecosystem is needed, alternatives such as Boohee, Keep, Huawei Health, and Apple Health may be worth comparing.
