Mobile considerations
---------------------
The Web export can run on mobile platforms with some caveats. While native
:ref:`Android <doc_exporting_for_android>` and :ref:`iOS <doc_exporting_for_ios>`
exports will always perform better by a significant margin, the Web export
allows people to run your project without going through app stores.
Remember that CPU and GPU performance is at a premium when running on mobile devices.
This is even more the case when running a project exported to Web (as it's
WebAssembly instead of native code). See :ref:`doc_performance` section of the
documentation for advice on optimizing your project. If your project runs on
platforms other than Web, you can use :ref:`doc_feature_tags` to apply
low-end-oriented settings when running the project exported to Web.
To speed up loading times on mobile devices, you should also
:ref:`compile an optimized export template <doc_optimizing_for_size>`
with unused features disabled. Depending on the features used by your project,
this can reduce the size of the WebAssembly payload significantly,
making it faster to download and initialize (even when cached).
