Keeps crashing after update
Please update again it keeps crashing now
Crashes on opening
App won’t even open. It flashes then crashes. No way to get my money back either, apparently.
Lame
Pretty much the worst $5 I’ve ever spent. Does not matter if I’m Bluetooth, wired CarPlay, wireless CarPlay. Tells me “low sample rate detected” and then reads no signal when I play the sound. I restarted the iPhone, restarted the uconnect, turned off all other apps and radios on my phone. Don’t bother with this junk if you are trying to figure out polarity on a 2025 wrangler.

EXCELLENT
Worked for my Jeep , Found out my Jeep Grand Cherokee front 2 door speaker were wired backwards, and all 3 dash tweeters also 🤦🏽♂️, After only reversing the the 2 front door speakers the sound system sounds so much better. Once I receive my adapters from Crutchfield I will replace the Tweeters. FOR THOSE OF YOU WHO DONT LIKE TO READ INSTRUCTIONS,HOLDING YOUR CLOSE TO THE SPEAKER EITH TEST TONE PLAYING IF THE PHONE READS A NEGATIVE IT MEANS THAT SPEAKER US OUT OF PHASE/POLARITY. All speakers should read + and not -

Chuchero testing
Used this app after I found my channels for my chuchero setup and it was accurate on the phase when I switched it on my drivers, mids, and tweeters.
Must have
This app accurately identified the speakers out of phase. Bluetooth connected, turned on the test tone, held my phone in front of each of the speakers.
Now my sound is great
My speakers really sounded bad. Somehow flabby. The app showed different polarity, so I changed the polarity of one speaker. Afterwards the sound was as expected. Thank you for this nice and simple app!
Didn’t work…
Follower instructions, Bluetooth and wired. I tested it on car speakers, my TV and the speaker I bought from the store. Even the speaker that was intentionally crossed wired
Non functioning
Designed very poorly and doesn’t seem to work via blueooth or irony. Playing the sound manual had no effect. Broken app
Best money spent on an app
Works great with Bluetooth, (doesn’t work when Apple Car Play is running, but does with Bluetooth) Within 2 minutes I was done. Found out 3 speakers were backwards, literally the most useful app I’ve ever downloaded.
Best $5 i’ve ever spent!!!
Moved into new house with speakers built in everywhere to the ceilings and walls. No idea how the wires are connected, and i’m not about to go around removing each speaker from the wall and ceiling to see how they are attached (i tried one one, but they are very difficult to remove).
I needed to know the correct polarity so that I could correctly calculate the impedance of various series and parallel circuits of speakers with the amp so i didn’t overload it (in addition to them having optimal sound).
The builders of my house did not seem to follow any sort of convention or pattern when installing the speakers and connecting the wires, unfortunately. Using the app I was able to see that approximately 25% of my speakers were wired backwards and I simply matched this backwards wiring on my wall plate to ensure that I have the correct polarity everywhere. This app save me hours and hours and hours of difficult work and I will be forever grateful!!!

Quick and easy
I ran the WAV click file from their website through my stereo (using my iPad), then held my phone in front of each speaker to check polarity. 3 out of 4 of my speakers were negative, so I reversed the wires on those. Very quick and easy.

Works like a charm
I’m a perfectionist and wanted my home theatre setup to have proper polarity. The speaker wires run through the wall so it’s difficult to know if positive/negative are flipped along the signal path. Rather than pulling out the multimeter and finagling a way to determine what is what, this app makes it a total breeze. Contrary to what an older review states, you can pipe the sound through your iPhone’s Bluetooth. Luckily my stereo receiver is Bluetooth enabled. I didn’t even care to isolate each speaker—it worked perfectly without that step. Get the pop going, adjust the volume on your phone to ensure signal strength is in the correct range, and the app does the rest. I know it works because when I tested the port on my subwoofer, it changed from “+” to “-“ as you would expect. All in all well worth the $7 to save a headache.

So simple with the right tools
What a great app !! I have an amp with 2 speakers on each channel and I’ve been noticing a drop in bass.
I assumed I’d blown a woofer (don’t lend your PA to friends !!) and was getting ready to replace it or maybe even get new speakers but had a nagging doubt that maybe I had wired the speakon connector incorrectly & therefore one speaker was out of phase.
Downloaded the app and within 2 mins had diagnosed & confirmed my suspicion.
Now they sound great !! Saved me money.
P.S Best way would be to download on to 2 devices. One as source for the all important sample tone & the other as diagnostic tool.

Works well
Exactly what I needed to troubleshoot speaker polarity and, by extension, phase for speaker pairs. Thank you.
Not Recommended
Why sell an app with a setting easily set by mistake that makes it give wrong readings! And there’s no documentation for that mono/bal “feature” either😖. Buyer beware! This cost me hours of time. I would like my money back.
Piece of crap
Save your money !!!
A miracle app!
This app saves me a lot of trouble by telling me which of my car speakers was connected properly or not (without having to disassemble my radio in my dash). Thanks a lot!
