Perform physics experiments with your phone. (by the RWTH Aachen University)
Pros & Cons
Direct access to on-device sensors enables hands-on physics experiments
Ready-to-run experiments let users start immediately with minimal setup
Flexible data exports to CSV, TSV, and Excel support easy analysis
Remote control and a web-based editor at phyphox.org enable collaborative work
No new downloads in the last 30 days, indicating limited recent growth
Demands multiple sensitive permissions (location, camera, microphone, storage, Bluetooth, etc.), which may raise privacy considerations
Some features rely on online resources (phyphox.org editor and online experiments), which may affect offline usage

Description
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 - Light intensity - Pressure - Microphone - Proximity - GPS *some sensors are not present on every phone.
Export formats - CSV (Comma separated values) - CSV (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.

Explanation for the permissions requested
If you have Android 6.0 or newer, some permissions will only be asked for when needed.
Internet: This grants phyphox network access, which is required to load experiments from online resources or when using the remote access. Both are only done when requested by the user and no other data is transmitted. Bluetooth: Used to access external sensors. Read external storage: This is may be necessary when opening an experiment stored on the device. Record audio: Required to use the microphone in experiments. Location: Used to access GPS for location-based experiments. Camera: Used to scan QR codes for external experiment configurations.
Recent changes: New camera-based sensors to measure luma, luminance, hue, saturation and value New camera-related experiments: Brightness stopwatch, color stopwatch, brightness spectrum New UI elements: Slider, Dropdown and Toggle Redesign of export/save dialogs to offer an additional download to filesystem button The deprecated Apache-based webserver has been replaced with jlhttp (big thanks to Amicha R.)

Excellent tool for doing easy physics experiments like measuring the acceleration of an elevator or plane!!! I like physics, hope you like it too!

This is what a utility app should be like. There's absolutely no ads or (from my experience) intrusive popups, it's completely free (although if your phone has some sensors missing you'd need to buy a new one, but that's not something the app can fix) and it has all the utilities and data exportation you could like.

After 40 years in technology there are few things that make me say "Wow, that's really cool!". This app however, is definitely one of them. What a useful and fascinating set of tools. Thank you for this app!
★★★★★Justin Knauf· Dec 12, 2025
Thank you, Chris Boden for the recommendation; I am definitely seeing something cool!

Download data, nothing. Waste of several experiments. Don't waste your time; data should be SAFE.

Great app but it only works once, then needs to be re-installed to work again.
