Smartphone as a measuring device and laboratory: phyphox app for iOS and Android

Smartphones are more than mobile phones with a few useful, entertaining and fun apps on the display. Modern iPhones and Android devices contain a large number of sensors that can be used to read and use data that is not only important for the system. Apps can also access and process the sensor data. The phyphox app for iOS and Android from RWTH Aachen University makes it possible to use it for interesting experiments. The software is free and can be used on Apple devices from iOS 9; the latest version of the Mac software, however, requires macOS from version 11 Big Sur and the M1 chip.

With the phyphox app you can use the iPhone sensors for experiments. RWTH Aachen University offers the app free of charge for iOS as well as for Android. There are also instructions for experiments and school materials. In this way, young and old can use the smartphone to develop a better understanding of physics and technology.

phyphox app - use iPhone sensors for experiments

The Apple iPhone has built in various sensors for the position in the GPS network, for the earth's magnetic field, for the acceleration of the device, for the air pressure and more. Audio signals can also be fed in via the microphone for evaluation. The named and other sensors are used in the phyphox app of the Rheinisch-Westfälische Technische Hochschule Aachen (RWTH) to carry out specified experiments or to enable your own test setups. An example: With the app you can measure the speed of an elevator in which you are. There are YouTube instructions and even school materials for further experiments.

On official website for the app you will find a list of the experiments and materials available so far. From the (in) elastic shock and the acoustic stopwatch to the measurement of acceleration and speed to sonar, air pressure and magnet examples, everything is included. In private life as well as at school or at university, the individual tools of the app as well as their recording and output options can help to develop a better understanding of physics and technology. For your own experiments and experiments, you can use the phyphox app to collect, save and output data in common formats for further processing.
