phyphox vs iDynamics

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 • 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.

iDynamics is an app for teaching and learning purposes. With this app any vibration and shock measurements and system identification analyses (e.g. determination of frequency and damping) can be performed. Furthermore, the app can be used for condition monitoring of the structure "Structural Health Monitoring". Thus, changes in the dynamic properties of the structure (e.g. due to damage) can be detected and evaluated. The application and use of the "iDynamics" app is intended for teaching and learning purposes only. The app will be further developed as necessary for the above-mentioned purposes. Other uses of the app outside of teaching, especially for legally binding and obligatory measurements as well as commercial use are not allowed or excluded.
