iOS and Android have converged on similar primitives (app sandbox, capability-based permissions, signed code, encrypted storage) but reach them differently. iOS: closed ecosystem, all apps from App Store, sandboxing strict, kernel patches Apple-controlled. Android: open ecosystem, Google Play + sideload, AOSP + vendor forks, kernel update lag.
iOS sandbox: every app runs in its own container, file access through entitlements. Cross-app communication via deep links, share sheets, XPC. Android: similar sandbox per UID, IPC via Intents + Binder. Storage Access Framework (modern Android) is converging toward iOS's strict model.
frida-server (Android) and an iOS jailbreak toolchain. Both are research tools for understanding what's enforced.
