Did you know that you are carrying a 3D magnetometer? That you can use your phone as a pendulum to measure earth's local gravitational acceleration? That you can turn your phone into a sonar?

phyphox gives you access to the sensors of your phone either directly or through ready-to-play experiments which analyze your data and let you export raw data along with the results for further analysis. You can even define your own experiments on and share them with colleagues, students and friends.

Selected Features:
- A selection of pre-defined experiments. Just press play to start.
- Export your data to a range of widely used formats
- Remote-control your experiment through a web interface from any PC on the same network as your phone. No need to install anything on those PCs - all you need is a modern web browser.
- Define your own experiments by selecting sensor inputs, defining analysis steps and creating views as an interface using our web-editor ( The analysis can consists of just adding two values or using advanced methods like Fourier transforms and crosscorrelation. We offer a whole toolbox of analysis functions.

Sensors supported:
- Accelerometer
- Magnetometer
- Gyroscope
- Pressure
- Microphone
- Proximity
*some sensors are not present on every phone.

Export formats
- CSV (Comma separated values)
- TSV (Tab-separated values)

A range of ways to measure the world around you with your smartphone. Very cool. Wonder if light level measurement (Lux) could be added using the light sensor or camera? I know some apps offer that.

Developer Response ,

Unfortunately, there is no interface for the light sensor. See for some more details.

Really cool physics experiment!

This is a really cool apps to experiment some physics. Some experiment also have video support.

Es kann nicht mit Cookie clicker mithalten

Developer Response ,

Tut mir Leid, zu hören, dass Ihnen unsere App nicht gefällt. Dass phyphox kein Cookie Clicker ist, werden wir wohl nicht ändern können, aber da viel Arbeit in der App steckt, würden wir uns dennoch freuen, zu hören was wir verbessern sollten.
