Frequency analyzer for iphone, useful at all ?

I downloaded 3 different audio frequency analyzers for my iphone and ran some pink noise through my system and placed my phone in the listening spot. Same level pink noise each test.
The curves are quite different from each other, although the seem to agree my room to be a bit 'bass heavy'
Are these analyzer apps useful at all or do one have to use more dedicated equipment to get more realistic measurements ?
Now this is what the 3 different apps came up with.
What do you think?

#1 : a linear frequency scale, half of the graph for 10k to 20k :no:

#2 : looks the most usable, huge drop in level from bass to treble ?
#3 : 33dB difference from 50Hz to 10kHz ???:yikes:

Were your tone controls flat, no loudness ?
My guess is that this is not really usable. Maybe I'm wrong ?

I dont know. I dont think the curves or level are correct. I think my sound is more 'flat' than these.
Also compared to other systems, mine is not this much 'bass heavy'.
I have noe tone controls, loudness buttons or equalizer in use. I have my bass ports pretty far from the wall, about 70 cm
I agree #1 is totally useless. The shape of the two others are not that far from each other, but dB level do not match at all
#2 probably has the best resolution.
 
OK
I rescaled the x axis to 0-8000 hz to improve resolution.
I took one shot of the graph with no sound at all and one with around 80 dB pink noise (80 according to spl level same app)
And then realized the sound of me pushing the screen shot buttons making the noise like this :p
I must find another way to capture the pic
