About phyphox
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 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
- GPS
*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)

1.1.10
Dec 13, 2021
- Experimental depth sensor support for devices with depth sensors (LiDAR/ToF). This feature is currently hidden. See https://phyphox.org/lidar for ways to try it.
- New sensor rate strategies (check https://phyphox.org/wiki for details).
- Translations of common units, quantities and similar short expressions are handled by the app and not in the file format, allowing for better translations.
- Fix: Analysis only executed once or not at all after user input if experiment is paused. (This for example caused the sample number in audio spectrum to only update after starting the measurement.)
- Fix: In remote access simple value elements break data requests for preceding graphs with same buffers. (Most notably breaking remote access for the inclination experiment and absolute plots on 3 axis sensors.)
- Load saved states on a background process and show the loading progress on screen to avoid watchdog kills in case of many large saved states.
- Fix: Clear in analysis resets to init value instead of emptying a buffer.
- Fix: Proximity sensor only works after rotating the device twice. (It still only works in portrait orientation and will turn off the display. This is beyond our control and a limitation of Apple's API.)

1.1.9

Fix: Reduce module produces additional zero value.
Fix: Wrong conversion of 24 bit integers (affecting both endianesses, signed and unsigned) for BLE inputs. (i.e. when using the pressure sensor of a SensorTag)
