Dayton Audio iMM-6 Calibrated Measurement Microphone for Tablets iPhone iPad and Android
The Dayton Audio iMM-6 is a professional-quality measurement and recording microphone that is designed to work with the entire suite of Apple "iDevices" - iPad, iPhone, and iPod (with 3.5 mm jack). The rugged construction and compact size make it the perfect companion for audio professionals who must work on-location performing acoustic analysis, monitoring audio levels, or recording. Each iMM-6 is individually hand-calibrated using a laboratory-standard measurement microphone, for consistent, repeatable measurements that match the level of precision previously offered only by expensive stand-alone microphones.
The IMM-6 uses an omnidirectional electret condenser capsule that allows for a single calibration file for high-precision measurements so you can measure the output of a speaker driver, or the response of a whole room!
Also compatible with Android and Microsoft devices that use a 3.5 mm TRRS jack, a headphone/line-out is built in for monitoring the recorded signal, and a kickstand elevates and angles the measurement capsule for more direct measurements. Each iMM-6 is ruggedly built with high-quality components and include a sturdy carrying case with foam insert.
A unique serialized calibration file is available for the iMM-6. This calibration file can be used by most audio-analysis apps for the iPad, iPhone, and iPod Touch (see compatibility list for recommendations). Visit the Dayton Audio calibration download tool, where you will be prompted to enter the serial number from the case of your iMM-6. After entering the serial number, your download will start.
Note: In order to use your iMM-6 as a calibrated measurement microphone you may be required to purchase an app for your tablet or smart phone.

I have been using one of these for years. Then I upgraded my phone and tablet to Samsung Android devices. Uh-oh, no headphone jack. I started out with one of the inexpensive usb-c to 4-pole headphone jack adapters. I could not get it to work, until I discovered the trick: you have to plug in headphones to get the adapter (actually a dac and adc built into a connector) to turn on. It worked, but SQ was not great, and dragging around headphones just to activate it was a pain. Then I tried the RDE AI-Micro usb interface. That thing worked right out of the box. Now I can do impromptu testing of live band sound, room acoustics, sound system behavior, etc. I am using the Sound Spectrum Pro App, which has an RTA mode that can run at 1/24th octave resolution. It is an amazing combination.

Easy to use probably not as accurate as the more expensive ones but will get your set up in the ball park

I used this microphone to measure the speakers in a three-way speaker rebuild. I used REW to test the speakers and then VirtuixCAD to design the crossovers based on the results of the tests. Being a newby to all of this, I don't know if I did everything correctly or if REW is even supposed to be used for this purpose, but the end product sounds great to me.One thing to note: I also got the recommended mobile app for Android, which seemed to work, but after a lot of back and forth I went with REW. Maybe I should have tried the ascending tone in the app rather than pink noise (which REW uses), but I felt more confident in the REW result.Another thing to note: in REW, I would recommend choosing to do multiple cycles (or runs) for each test, and it will automatically average them.
