Love the app BUT the heat

Not sure if anyone else is having this issue, but this app makes my iPhone 12 HOT after 15 mins of use, which is a big-time bummer as i wanted to use this app to monitor my trans temp, it works, BUT my phone will shut off from the heat...

Waste of money

None of the gauges are accurate. Not even close. You essentially spend money on a code reader

Doesn't work and support is unhelpful

This app didn't work on my iPhone or iPad. I asked for a refund and all I got was an insistence that it works and no refund.

Great app.

Thanks so much for the updates!!!

I use this with a veepeak elm327 scanner and it works perfectly. It’s helped me track down a few issues with my ranger and also helps me monitor its operation. Especially helps since I do my own repairs, I can verify and monitor readings with the workshop manuals.

Works great!

This app has more than just check engine code reading. I have had my car for 3 years and I am on a stage 2 ecu tune. I have always wanted to know what boost pressure I was running but, I don’t have a boost gauge. This app tells you boost pressure! :) pretty cool!!
