Ant Afu: Ant Group's AI health app tops China's App Store free chart

A standalone consumer app that answers health questions, reads and explains medical-exam reports with AI, and connects users to digital hospital services — built by Ant Group on a medical large model and linked to about 5,000 hospitals and 300,000 real doctors.

That a free AI health assistant backed by 300,000 doctors could make Ant the default health app for Chinese families — carrying Alipay's trust into lower-tier cities.

In December 2025 Ant Group shipped a new version of its AI health assistant app Ant Afu (蚂蚁阿福) — an independent health app built on a medical large model that answers health questions and links users to digital medical services. The company connected it to health commissions, medical-insurance bureaus, roughly 5,000 hospitals and 300,000 real doctors.

Growth spiked during the 2026 Spring Festival travel season: a 'health blessing' (健康福) campaign with red-envelope activities, plus young people returning home to teach parents the app, pushed downloads sharply up. On Feb 14, 2026 Ant Afu hit #1 on the China App Store free overall chart, ahead of Qwen at #2, and that same week Ant announced the app was becoming a CCTV health-life partner. On May 6, 2026 Ant Group signed the strategic cooperation with China Media Group; Ant said users had passed 100M (55% from tier-3 and below cities), that the platform handled tens of millions of health queries daily, and it launched a free AI report-reading drive aimed at 100M people.

Still scaling as of 2026-09-02: Ant calls Ant Afu the world's largest health-AI app by users and is deepening the CCTV-backed free report-reading push; the February chart win came from a campaign spike and Ant has not disclosed sustained rankings, but the app anchors its consumer-AI strategy alongside Alipay.

Trust transfer: in a high-stakes category like health, Ant leaned on real doctors, hospitals and public institutions rather than selling AI cleverness alone.

A universal pain point: 'I cannot read my medical report' is near-universal in China, and free AI interpretation gave people an obvious first reason to install.

Family-as-distribution: the Spring Festival ritual of returning home let younger users onboard parents and grandparents, pushing the app into lower-tier cities (55% of users).

Institutional partnerships compounded the surge: health commissions, medical-insurance bureaus and CCTV gave the app authority that chart position alone could not buy.

The spike-to-platform test: campaign-driven chart leadership is easy to measure and hard to sustain, so retention beyond the festival is the real bet.

Trust-heavy categories reward credible anchors: hospitals, 300,000 doctors and a CCTV partnership vouched for the AI, while a family-teaching campaign turned Spring Festival returns into onboarding.

As of 2026-09-02, Ant Afu is still scaling: Ant says it is the world's largest health-AI app, with over 100M users (55% from tier-3 and below cities) and tens of millions of health queries a day (CNR, 2026-05-07). The free report-reading push and CCTV partnership keep expanding, while the Feb 14, 2026 #1 chart position was campaign-driven and no sustained ranking data has been published; Ant has not disclosed revenue or engagement metrics, so the open question is whether free health AI converts into durable usage.
