User reviews of FrequenSee - Spectrum Analyzer
Excellent App. I'm a DJ an place it on my board to monitor for feedback frequencies. It looks great and helps me quickly locate mic feedback and kill it. Surprisingly accurate considering it is using the phone mic for input!

Very accurate Accurate for a phone app. Could use some more bells and whistles such as: a option for bars instead of a wave. Tap a frequency for more exact number. Calibration. Peek recordings.
