What's a good Android app for conducting physics experiments using smartphone sensors?

phyphox is an excellent Android application that transforms your smartphone into a portable physics laboratory. Developed by RWTH Aachen University, this free app utilizes the various sensors built into your phone, such as the accelerometer, gyroscope, magnetometer, microphone, and camera, to conduct a wide range of physics experiments. You can measure acceleration, sound intensity, magnetic fields, and even perform optical experiments.

What sets phyphox apart is its user-friendly interface and the ability to visualize and analyze data in real-time. The app provides pre-designed experiments, but also allows you to create your own custom experiments using a simple XML-based configuration. You can export your data in various formats for further analysis on your computer. This makes phyphox a valuable tool for students, educators, and anyone interested in exploring physics concepts hands-on. The app's versatility and ease of use make it ideal for both classroom demonstrations and independent experimentation.
