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)
- Excel
(if you need other formats, please let us know)

This app has been developed at the 2nd Institute of Physics A at the RWTH Aachen University.

Waghon ,

Can I use it when screen locked?

App is great, nothing to complain

Hey, devs, have u guys consider making it work on the background/screen locked?

Entwickler-Antwort ,

We have certainly considered it, however, it is quite a task within the limits of background app policies. So do not expect it any time soon.

Great App with some math

I am using accelerometer only so far for measuring and recording car acceleration.
With low pass filter (FIR) and coordination translation, it works very well.
My car has wireless phone charger, about 37 degree angle. To calculate lateral acceleration, the raw data (y-z) must be transformed by using sin() and cos().
You can use phone app to measure angle.

Thank you. :) Many of these operations could be done in phyphox itself with

This app has functionality for every sensor in my phone... even ones I didn’t know I had! I especially enjoy the Everyday Life applications like the “Applause Meter”. All in all, this app is for those who cannot access scientific sensors for their projects by unlocking the various sensors in one’s phone. Great job.
