Comments on Spectrum analyzer for Android

★★★★★ Roger Ballard · Dec 1, 2025

It shows my heater, Wi-Fi, apple air tag, frequencies from 0 hz to 20,000 hz. I use it to check for the 1.6 giga hz to 1.8 giga hz used for earth to space communications. Aliens

★★★★★ Thomas Potthast · Dec 11, 2025

Helpful in dialing in home theater speakers. Responsive, informative, and the ads are reasonable. I wish you could zoom in a little more on the bottom view and would love an option to show overall sound pressure level in dbc as well as dba.

★★★★☆ R C · May 25, 2026

It needs an option for logarithmic frequency scale, and ability to calibrate.

★☆☆☆☆ CC Epping · Dec 29, 2025

Doesn't allow what it describes. Books not available

★★☆☆☆ Dawson Jacobs · Jul 30, 2025

Not very informative. Unable to understand the purpose
