Mobile app development using Python is possible through various frameworks and tools that allow you to create cross-platform applications for both iOS and Android platforms. 

Here are a few options:

Kivy:

Kivy is an open-source Python library for developing multitouch applications. It’s particularly well-suited for creating touch-based mobile applications. Kivy supports various input methods, and its code can be used to target different platforms.

BeeWare:

BeeWare is a collection of tools for developing Python applications that run on different platforms, including mobile devices. Toga is a part of BeeWare that allows you to create native applications for iOS, Android, and desktop platforms using the same codebase.

PyQt and PySide:

PyQt and PySide are Python bindings for the Qt application framework. While primarily used for desktop applications, these libraries can also be utilized to develop mobile applications. Note that using these libraries for mobile development might require some additional effort.

KivyMD:

KivyMD is a Python library that builds upon Kivy to provide Material Design components for your mobile applications. It’s suitable for creating visually appealing and functional cross-platform mobile apps.

SL4A (Scripting Layer for Android):

SL4A allows you to use various scripting languages, including Python, to interact with Android’s API. While not a traditional mobile development framework, it’s useful for creating scripts that can control Android devices.

PyJNIus:

PyJNIus is a Python library that allows you to access Java classes and methods from Python. It can be used to build Android applications using Python while leveraging Java APIs.

Chaquopy:

Chaquopy is a plugin that allows you to include Python code in your Android applications. This can be useful when you want to combine Python with Java/Kotlin code in an Android project.

It’s important to note that while these frameworks and tools enable you to use Python for mobile app development, they may have limitations compared to native development in terms of performance and access to platform-specific features. However, they can be a great choice for cross-platform development or when you want to leverage your existing Python skills for mobile development.

Before choosing a framework, evaluate your project’s requirements, target platforms, and the level of access to native features you need. Additionally, keep an eye on the maintenance and community support of the chosen framework to ensure its longevity.
