An application for room acoustics measurements has been developed for Android devices: its novelty represents the use of the logarithmic sine sweep method, which is better than typical direct methods used so far. The article describes the main points of the design phase and stresses the instrument on-site testing results in common use rooms. The testing of this Android instrument gives insights on small-room acoustics and on acoustical parameters measurement quality.
