5/5Best $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!!!

5/5EXCELLENT
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 -

5/5Best 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.

5/5Perfect!!!
Just built a new audio system in my car and I was struggling with some weird polarity issues coming from the OEM head unit. I downloaded and burned the WAV file to CD and played it on repeat. And then one by one I could test each speaker simply by hold my phone near it. Brilliant!

5/5Quick 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.
