Are there any android apps for measuring loudspeakers?
Be it for free or for money?
I can use a smartfone as source and another one for measuring frequency response and waterfalls.
Distortion is not necessary.
Implemented microphones should be enough linear in the mids where it is most important.
Highs and lows are always adjusted to taste.
The most important region is 200hz to 8khz.
Even if integrated mic deviates outside of this band I will find that easily out measuring well known responses from existing drivers.
I can tell that "Spectroid" is a good tool for getting an impression for frequency response but it is not ideal.
Also you can download white and pink noise signals from YouTube and extract the audio. If you look for "YouTube to mp3 converter" you find the tools online.
Who knows more?
Which apps will do?

There is Winlator for android;

Which is a way for running x86 programs on you android device.
Programs like ARTA seem to work fine, I haven't tested it yet with an audio device.

I got a Dayton iMM 6, but I had no luck with the measurement due to phone limitations. The idea was to use the SMSL B1 BT receiver and that microphone, but for now it's sitting there waiting for the bether phone. And I have other measuring equipment, so I can compare. Let's say the phone begins to cut the range below 100Hz and above 12kHz, with some peaking at 16k, and in between is acceptable. Now I see that there are new versions of that microphone with a different connections. Maybe a USB connection would give a better result. Mine is TRRS 3.5mm, it goes to the headphone and mic jack.

Audio Tools - nice tip
Here I found Spectroid:

This here I will try out Room Acoustics meter from Mr. Gaus (nice name!):

Does anyone know if there is an Auto EQ android software like / similar to the one in the Behringer DEQ2496?
Wavelet app has a sort of auto eq.
Player apps like jet audio and neutron player have 20 and 60 band eq integrated

Neutron Player is very sophisticated!
There is a free version - do not know what is the downside of this (maybe it forgets its settings). The payment would be only something like 9 euro for the full version software.
It has parametric EQ (!) And you can adjust a lot of bands already in the free version.
It offers also Auto EQ with a plugin you have to download.

What is your goal here? First you ask about speaker measurement and then you make posts about audio players? The "Auto EQ" feature in those players are just EQ presets for specific headphones.
You measure so you can adjust an EQ.
So integrated EQ and playing white noise signal allows for real time frequency response adjustment by hand.
Tested now spectroid app and it allows for clearing the max hold.
So a sweep from 20hz to 20khz shows F response and for any new look at a done correction I clear the max hold

External EQs will do the same. But nice to see parametric EQs they are powerful tools.
Interesting would be how much integrated standard smartfone Mics deviate.
Anyone knows collected measurements from these in a diagram?

OTG not enabled on your phone?
The ability to use the usb as an input, not just output.
I'm looking at this mics myself. For running REW on the PC. A USB extension will make it mobile. I'm not sure it will be great though. There seems to be no calibration file.
I measure with white noise and Spectroid app works well.
here a measurement of an 8cm fullrange close to back wall
the room acoustics meter from mr gauss has a less good visibility and measured less good in response

I also use spectroid, and white noise and sweeps from youtube. I know my phone's mic is a very weak link, but it shows the spot frequencies of room gain and dips I can hear. Making it easy to set up some filters, just to level out my response curve. It's both imperfect, and loads better.
I could drag my speakers outside, and set them up there. However, it's better to set them up in-situ. Making them the best fit for my room. Not perfect in some situation I don't live in.

the 8cm fullrange I use was perviously measured with atb pc 501 hardware measurement system from Kirchner Elektronik. so i know it.
with my smartphone and spectroid it measures correct 15khz upper frequency limit, with the room acoustics meter it showed 9khz, I know the fullrange goes to 15/18khz.
