About this app

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 phyphox.org 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 (http://phyphox.org/editor). The analysis 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
• Light intensity
• Pressure
• Microphone
• Proximity
• GPS
• Camera
• LiDAR/ToF
*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.

Ratings and reviews

Honestly, a really cool piece of work! Simple to use and operate, and really opened my eyes as to the sheer amount of STUFF my phone has to offer in terms of telemetry. I think what really opened my eyes was being able to detect the minute, fraction-of-a-decimal differences in barometric-pressure between various rooms in my home, from floor to ceiling. Impressive stuff! Definitely worth having on-hand.

Really useful app, but why can't it keep running in the background to collect the data on a 5-6km road I need to make sure the app remains open on the screen and the phone doesn't get an auto screen lock.Thisnis something that should be addressed, it should keep running in the background until I terminate it.

Really, really cool. Easily now my favourite app on my phone. I cannot believe this has no ads and is entirely free. Just goes to show what can be produced when you just want to help people around the world do experiments. I found it essential for adding the finishing touches to a pulsing electromagnet, where other apps couldn't quite capture every pulse. This app smashed it!! Awesome.
