Xiaomi's Fitness App Teams Up With AI Doctor Ant Afu
Xiaomi Mi Fitness Gets Smarter With AI Health Assistant
Xiaomi's popular Mi Fitness app just got a major upgrade by integrating with Ant Afu, Ant Group's artificial intelligence health assistant. This partnership marks a significant step forward in making health tracking more intelligent and actionable for everyday users.
Your Pocket Health Consultant
The latest version of the Mi Fitness app now allows users to tap into Ant Afu's capabilities directly from the sleep and heart rate monitoring screens. Instead of just collecting numbers, your fitness tracker can now offer meaningful insights about what those numbers actually mean for your wellbeing.

"We're moving from passive data collection to active health guidance," explains a Xiaomi spokesperson. "When your watch records an unusually high resting heart rate or poor sleep quality, Ant Afu can immediately analyze potential causes and suggest improvements."
Powered by Medical AI
The secret behind this smarter approach lies in Ant Afu's advanced medical large language model. Unlike basic fitness apps that simply log your stats, this AI assistant can:
- Interpret patterns in your health data
- Provide context about what's normal or concerning
- Offer practical suggestions tailored to your lifestyle
The system doesn't replace doctors but serves as a helpful first opinion—like having a medically knowledgeable friend always available.
Expanding Ecosystem
This collaboration represents part of Ant Afu's broader strategy to integrate with popular devices across the tech landscape. Since rebranding from AQ last month, the assistant has enhanced its three core functions:
- Health companionship - Continuous monitoring and check-ins
- Q&A - Answering medical questions in plain language
- Services - Connecting users with relevant healthcare resources
The assistant already works seamlessly with devices from Apple, Huawei, vivo, Yuwell and Omron—nine major brands in total.
Growing Popularity
The numbers speak volumes about how quickly consumers are embracing this AI health revolution:
- 30 million monthly active users
- Over 10 million daily AI-powered questions answered
- Rapid expansion across multiple device ecosystems
As more people prioritize preventative healthcare, tools like Ant Afu integrated into familiar fitness apps could become our first line of defense against potential health issues.
Key Points:
- Xiaomi Mi Fitness now includes Ant Group's AI doctor functionality
- Provides real-time analysis of sleep and heart rate data
- Uses medical LLM to offer personalized suggestions
- Part of Ant Afu's expansion to multiple device brands
- Already serving 30 million monthly users
