If you think this app is worth a shit, I'll do some testing, just tell me what you want.

I can get pink noise sweeps, 0-100Hz sweeps or just specific tones, Google play has test tone playlists...

Highly doubtful.
What do you mean by "seems to have a higher pitch". Do you mean that the tweeter in the other is nor working correctly? You could use a cheap microphone to do frequency response measurements on both. If you have an android phone, you should be able to use a free frequency analyser app such as RTA audio analyser.
Yes, white noise surely :)
Actually, it would depend on the kind of spectrum analyzer we are using. SpecScope shows FFT, and white noise shows up flat here. If we were using RTA spectrum analyzers, either hardware or probably this app, pink noise would show up flat.
