phyphox

Did you realize that your smartphone houses a 3D magnetometer, allowing you to explore magnetic fields? Or that you can harness its capabilities to transform it into a pendulum for measuring Earth's gravitational acceleration? Furthermore, with phyphox, your phone can double as a sonar device, opening up a world of possibilities for experimentation and exploration.

Phyphox provides smooth access to your phone's sensors, either directly or through a series of ready-to-use experiments. These experiments analyze your data and offer the flexibility to export raw data and results for further analysis. Additionally, users have the freedom to define their own experiments on phyphox.org, enabling easy sharing with colleagues, students, and friends.
