Comments on FrequenSee - Spectrum Analyzer for Android

★★★★★ void null · Nov 25, 2025
Great spectrum analysis app for human audible sound
★★★★★ Peter Marshall · Mar 10, 2023
This is the one! Responsive, accurate for the purpose, excellent display. No frills, it just does what it should. Invaluable for hunting feedback in audio reinforcement (PA) systems. It's always with you and it's free. Ads are unobtrusive. Thanks, Daniel!
★★★★★ Eric Bogle · Jan 16, 2024
Good app for seeing sound frequencies and finding feedback. Free on Android, paid on iOS. I wonder why.
★★★★★ Casey Baker · Jul 3, 2020
I love this app. Would particularly love a way to analyze from an external input (line in or external mic).
★★★★★ Dennis Moore · Mar 23, 2019
Clean and Simple. Only way the app could be better would be to add a decibel meter, or make it split screen compatible so I could use a sound meter app in the other screen.
★☆☆☆☆ Robert Zinda · Jul 17, 2021
I put some time into testing a bunch of this audio frequency and decibel apps using 4 different devices and none were able to do anything even close to what real spectrum analyzer was showing! Each device showed a completely incorrect reading. I couldn't even get any apps to match any other apps readings on the same device with them both running at the same time with pink noise sent from real RTA. Incredibly useless, use this to tune a stereo, and you'll be wondering what happened to it.
