Phyphox is an app that allows users to utilize their smartphone's sensors in various experiments. The app features include data export, remote control, and custom experiment capabilities. With Phyphox, users can detect frequencies, measure sound waves, and analyze data in multiple formats.

The team behind Phyphox has received several awards for its innovative teaching tool. In 2020, the Ars legendi-faculty award was given to Prof. Heidrun Heinke and her team for their development of Phyphox and its impact on academic teaching and physics classes. The app has been widely used in Germany, particularly among students who have praised its effectiveness.

Phyphox was developed at the RWTH Aachen University's 2nd Institute of Physics by a team of researchers, including Sebastian Staacks, Christoph Stampfer, and Heidrun Heinke. The team has grown to include numerous contributors, with a global ambassador program providing support and resources for users worldwide.
