Misleading health claims in apps can lead consumers to forgo professional medical care, creating real patient safety risk — Apple's requirement that health apps disclose limitations and recommend professional consultation is a consumer protection measure with life safety implications.
Apple's App Review Guidelines directly affect what apps consumers can access, what data those apps may collect, and how they can pay for digital content — Apple's mandatory in-app purchase requirement means app developers cannot offer cheaper prices through external payment links on iOS. Consumers benefit from Apple's content and privacy review standards, which prohibit apps from collecting data beyond declared purposes and require age-gating for adult content, but have no direct appeal mechanism if Apple removes an app they rely upon. You can review an app's declared data practices by checking the App Privacy section on any App Store listing before downloading.
