# Native modules

Cross-platform wrappers around device APIs that are not part of the
view tree: camera, GPS, file I/O, notifications, clipboard, share
sheet, deep links, permissions, connectivity, secure storage, battery,
haptics, and biometrics. Each module is a Swift and a Kotlin class
registered by name in the native runtime; the Python classes below are
facades that call them through
[`native_module`][pythonnative.native_modules.registry.native_module],
with a Python implementation registered for the desktop and tests.

Both synchronous and coroutine APIs exist (chosen to match the
platform call). For the call-site patterns, the reactive
`use_app_state` / `use_net_info` hooks, and the runtime coroutines are
scheduled on, see the [Native modules guide](../guides/native-modules.md)
and the [Async + data guide](../guides/async.md).
