Using on my Amazon Fire 10. Great tool for anything amplitude/frequency related. Good look to the app, and has all the options you need in a portable AF spectrum analyzer. Over the years, I've paid hundreds of dollars for actual intstruments that didn't work as well. I'm a retired electronics engineer (45 yrs on the job) and love all these new gadgets and apps.

Does one thing well! I use this with a clip-on microphone (guitar tuning mic thing) to monitor the health of high-speed motors. The waterfall and the FFT are really handy for spotting harmonics that shouldn't be present in my pumps so I can take care of maintenance long before anything breaks. Also great for looking at bird calls to help identify them by sight...if you know what the spectrogram of the call looks like...but you can learn that while playing with this app!

Good app as far as it goes. I am building tuned struck instruments. Tuning is a 'B'. Unfortunately the apparent 12Hz bins do not provide sufficient resolution. According to the description in the Pro offering, it only extends the resolution down to 3Hz. No technical description, so no way to tell if you have implemented decimation in the Pro version. Sticking with Spectroid for now.
