Apple Cracks Down on Cal AI Over Payments
Apple briefly removed the Cal AI food‑logging app (owned by MyFitnessPal) from the App Store after finding multiple violations of its App Store rules tied to external payments and billing design. Apple said Cal AI implemented an embedded third‑party payment flow (using Stripe) that bypassed Apple’s in‑app purchase option, and that the app used deceptive billing displays and other manipulative tactics in violation of its review guidelines. Cal AI corrected the issues and the app was reinstated. The episode underscores that Apple continues to enforce its App Store payment and developer‑conduct rules even after court rulings have loosened some restrictions on linking to external payment systems.
Major platform (Apple) enforcement of App Store payment and developer‑conduct rules affects app monetization and compliance practices across the ecosystem following the Epic ruling.

MyFitnessPal Acquires Viral Teen-Calorie App Cal AI
MyFitnessPal acquired Cal AI, a photo-based AI calorie-counting app founded by two high-schoolers, after nearly a year of talks, closing in December. Cal AI had over 15 million downloads and $30 million in annual revenue in under two years. MyFitnessPal retained Cal AI's seven-person core team, including co-founder/CEO Zach Yadegari, and integrated it with its nutrition database (20 million foods, 68,500 brands, 380+ restaurant chains), while keeping Cal AI as an independent product. Financial terms were undisclosed. Separately, Yadegari has launched a new AI agent startup called Persona, raising $10 million in funding led by Vine Ventures, with participation from Cory Levy and Collective Global. Persona is a privacy-focused personal AI assistant with an optional $179 wearable band, shipping in December, which monetizes via advertising during shopping research.
Apple Blocks AI 'Vibe Coding' Apps
A CNBC opinion column reports that Apple has blocked updates for at least two 'vibe coding' AI coding apps (including Replit) and removed one, citing safety concerns. The column argues Apple's enforcement on apps that let non-developers build and preview software inside apps or browsers may push new builders to the open web, potentially hurting the iOS app ecosystem and Apple’s Services revenue. The piece notes Apple still added AI tools from OpenAI and Anthropic to Xcode in February, highlights data showing a recent surge in App Store releases, and quotes users and experts who warn inconsistent enforcement and platform-protection incentives could redirect innovation outside Apple's closed App Store environment.
China Pressures Apple Over App Store and AI
Apple faced intensified pressure from Chinese authorities and state media after a People’s Daily editorial criticized the company’s App Store practices. Tim Cook travelled to Chengdu amid criticism and after Apple cut its App Store commission for Chinese users from 30% to 25%, a move Beijing said was insufficient. Apple’s generative-AI product, Apple Intelligence, remains unavailable in China because of regulatory delays, while domestic rivals (Huawei, Xiaomi) ship devices with on-device AI. The piece places Apple’s situation in a broader pattern where Western firms that derive large revenue shares from China face recurring regulatory leverage. The article also covers China’s push toward de‑dollarization via expanded cross-border digital yuan settlements and a domestic cultural policy axis—museum expansion and a simultaneous mental-health therapy boom alongside tightened online content controls enforced by the Cyberspace Administration of China (CAC).
