User reviews

Worthless

Installed app and it worked fine on android. Now it opens and connects then immediately closes out with no error message or anything. Open app again and same thing, uninstalled.

App was upgraded and now its useless keeps crashing

App keeps crashing after upgrading

Poor App lets the whole thing down

The hardware part is great but the app lets the whole system down, crashes constantly when used on my iPhone XS. I then have to close the app and restart and reconnect only for it to crash again.
It’s a real shame as it has so much potential but the constant crashing renders it useless.

Terrible product

PLX's mission statement is "to design the world's most innovative products and deliver a world class customer experience”
PLX Multigauge falls incredible short of that goal. Dealt with their support team for more than a month, trying different IOS devices and IOS releases. At best, I can get about three seconds of data before the app freezes (the controller continues to put out the correct voltage levels). Sent the unit back to PLX, and they reported that “it worked perfectly”. Apparently they don’t consider the software to be part of their product. An awful experience, time lost and money down the drain.

Crashes

App freezes or crashes within 30 seconds of starting the car. I purchased the analog gauge and it works fine.
The app needs to be fixed.
