pyobjc-framework-CoreMotion

What it is and what it does

This package wraps Apple's CoreMotion framework for use in Python, allowing developers to access motion and activity sensor data on macOS. It is part of the PyObjC project, which provides a bridge between Python and Objective-C frameworks on Apple platforms. The wrapper does not include its own documentation; users must consult Apple's CoreMotion documentation alongside PyObjC's general translation guides to understand how to use the framework from Python.

The package depends on pyobjc-core and pyobjc-framework-Cocoa and is available only as pre-built wheels for macOS. It supports Python 3.10 through 3.15, including free-threading builds for Python 3.13+. Installation is straightforward on supported platforms, and the project is actively maintained with recent releases.

Use it for:

• Build macOS applications that respond to device motion, such as gesture recognition or tilt-based controls.
• Collect accelerometer and gyroscope data from a Mac for research or fitness tracking applications.
• Detect user activity (walking, running, stationary) on macOS for context-aware application behavior.
• Develop accessibility tools that adapt to user motion or activity patterns on macOS.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides Python bindings to macOS's CoreMotion framework, enabling access to motion and activity data from device sensors like accelerometers and gyroscopes.

Yes, if you are developing on macOS and need native access to motion sensors. The package is actively maintained, has no known vulnerabilities, and carries a permissive license. Install friction is moderate due to platform specificity and Python version constraints, but pre-built wheels minimize setup complexity. Not applicable on non-macOS systems.

Install

pyobjc-framework-coremotion on PyPI

pip install pyobjc-framework-coremotion

uv add pyobjc-framework-coremotion

poetry add pyobjc-framework-coremotion

Installing pyobjc-framework-CoreMotion

Before you install

Medium install friction: platform-specific wheels for macOS only (Python 3.10–3.15, including free-threading variants). Requires pyobjc-core and pyobjc-framework-Cocoa. Active maintenance with a recent release (3 days old) and steady repository activity.

License in practice

MIT license is permissive; no restrictions on commercial or proprietary use, modification, or redistribution provided the license and copyright notice are retained.

Quickstart

pip install pyobjc-framework-coremotion

from CoreMotion import CMMotionManager
manager = CMMotionManager()

macOS only; requires Python 3.10 or later and a compatible macOS version (10.9+ for most wheels, 10.13+ for Python 3.12+, 10.15+ for Python 3.14+).

Verify before relying

• Specific CoreMotion capabilities exposed (e.g., which motion sensors, data types, or APIs are wrapped).
• Whether the wrapper covers the full CoreMotion API surface or a subset.
• Real-world performance or latency characteristics for sensor data collection.
