phyphox: Physics Phone Experiments – A Mobile Laboratory for Science Education

phyphox is a mobile application developed by RWTH Aachen University that transforms a smartphone into a versatile physics laboratory. It leverages the device’s built-in sensors, such as accelerometers, magnetometers, gyroscopes, and microphones, to conduct accurate scientific experiments. The app requires no external hardware and supports real-time data collection, analysis, and export. Designed for educators, students, and hobbyists, phyphox offers pre-built experiments or allows users to create custom setups using the sensor interface. It is available on Google Play and the Apple App Store, providing a cost-free tool for interactive physics learning.

Chapter 1: Function

phyphox’s core function is to harness smartphone sensors for precise physical measurements. The app includes over 30 pre-configured experiments, such as measuring gravitational acceleration with an accelerometer, analyzing sound frequencies using a microphone, or tracking rotational motion with a gyroscope. It supports multi-sensor synchronization, enabling experiments like pendulum analysis or magnetic field mapping. Users can record data in real time, visualize results through dynamic graphs, and export raw data in CSV format for external analysis. The app also provides a remote control feature, allowing experiments to be triggered from a computer via Wi-Fi or Bluetooth. Additionally, phyphox includes a sensor calibration tool to minimize errors, ensuring reliable measurements for both simple demonstrations and advanced research tasks.

Chapter 2: Value

phyphox delivers significant value by democratizing access to scientific instrumentation. Traditionally, physics experiments require expensive laboratory equipment, but phyphox turns any smartphone into a functional lab tool at zero cost. This reduces financial barriers for schools, universities, and individual learners, especially in resource-limited settings. The app enhances conceptual understanding by linking abstract physics principles with tangible, interactive measurements. For educators, phyphox offers ready-to-use experiment templates and remote monitoring, simplifying lesson planning and enabling in-class or at-home assignments. For researchers, its high-precision sensor data and exportability support pilot studies or field measurements without bulky gear. The open-source platform allows advanced users to customize experiments, fostering innovation. Moreover, the app operates offline, ensuring usability without internet dependency. By integrating data analysis and real-time feedback, phyphox promotes active learning, critical thinking, and practical skills, making it a powerful educational asset.

Chapter 3: Scenarios

phyphox primarily targets students and teachers in secondary and higher education, particularly in physics, engineering, and environmental science courses. It is also used by hobbyists and citizen scientists for DIY projects, like analyzing vibration patterns or calibrating home sensors. Everyday use cases include a high school classroom measuring the local gravitational constant using a phone drop experiment, or a university lab studying centripetal force with a rotating smartphone. Outdoor applications, such as measuring acceleration in a moving vehicle or recording sound spectrum in a concert hall, demonstrate its versatility. In remote learning scenarios, students can perform experiments at home and share data via export to collaborative platforms. The app also serves professionals, such as acoustic engineers, for quick field measurements. Its adaptability to diverse learning environments, from formal labs to informal exploration, makes it a practical tool for anyone curious about the physical world.
