Spectroid
Carl Reinke
Real-time audio frequency spectrum analyser with high resolution, logarithmic frequency display, and spectrogram history — one of the highest-quality free audio analysis tools available on Android.
RWTH Aachen University
University-developed physics experiment app that accesses all device sensors with full data export and remote monitoring — the most scientifically rigorous multi-sensor tool available on smartphones.
Developed by RWTH Aachen University for physics education and research. Provides direct access to the magnetometer, accelerometer, gyroscope, barometer, microphone, light sensor, and proximity sensor with configurable sampling rates and full data export to CSV. Includes pre-built experiment templates and a remote monitoring mode (view live data on a desktop browser over the same WiFi network).
