This update improves the signal processing in general. Meanwhile, I have released my second app "liveBPM". If you are a musician or DJ, be sure to check it out!

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!

A fun app I can see how this would be very useful for a specific group of people. My kids like playing with it, and I kind of do too. I'd like to have the option to turn the camera on & have it record video with the frequency spectrum line superimposed. "Yes dear, you were snoring - and it was THIS loud!"
