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.

FAQ

What does this app do?

This app functions as a speaker polarity tester. It helps you determine if your speakers are wired correctly, meaning they are in phase or out of phase. By analyzing a proprietary "pop" sound emitted by the speaker, it can detect if the speaker cone is moving in the correct direction, identifying reversed wiring.

How do I use this app to test my speakers?

Once the test signal is coming from your speaker, position your phone near it, ideally with the internal microphone pointed directly at the speaker. The app will then analyze the sound and display a reading of either "Plus" for correct polarity or "Minus" if the wires need to be swapped.

What kind of speakers can I test with this app?

This app is designed to work with any speaker that has wiring terminals on the back. It includes automatic adaptive technology to support all speaker types, including woofers, midranges, and tweeters, ensuring reliable readings regardless of the speaker component.

How can I connect the app's test signal to my speakers?

For iOS devices with headset jacks, you can use a standard 1/8" stereo plug and an appropriate adapter to connect to your system. Alternatively, you can record the test signal to a CD, DVD, or another device and play it through your speakers. The app also supports Bluetooth and AirPlay streaming to compatible devices.

Is this app free to use?

Yes, this application is available for free. There are no in-app purchases or advertisements mentioned in the provided description, indicating a completely free user experience.
