Reviews for Gretio - Automotive Scan Tool

This app helped me repair my car! It's Great!

I cannot get this stupid thing to work with my OBDlink mx+. It will not recognize my 2005 Suburban at all when I plug it with the device I listed it would work with my Chevy Cruze.

The best scan tool and monitor for GM vehicles, especially diesel

Does not support OBDLink MX+ even though it states it does. Cannot use.

Super support for my application. Excellent value.

I wish there was an android auto version so I could watch values as I'm driving, but it is an amazing tool that helps me out a ton with GM specific commands and PIDs, using a cheap little OBDLink LX!

Keeps disconnecting on multiple phones when Torque Pro has zero issues

Spent a good hour or more. Trying to get this app to work won't stay connected to the v linker mc+

Won't work with OBDLink MX+. Other apps instantly connect, this one says unsupported protocol even though OBDLink is all over the app.

It was able to connect to my OBDLink MX+. It took only a couple of minutes to clear and relearn my FOBs.

Gretio is a one of a kind tool for GM vehicles, have started using it at my shop for a few of our L5P and L5D diesels. If you're looking for an inexpensive and feature rich app, this is for you. And yes, this app is great if you need to do manual service regens on your Duramax.

I need to be able to test the tamper system for my exhaust in my 2011 Silverado duramax and it's in the glow plug module but I don't have access to it it says the module isn't supported or something and I really need to test it.

Bummed it does support Android Auto yet. Would be nice to see gauges in a grid. Also had a bit of trouble setting up OBDLink MX. I didn't expect to have any issues but, I did. it works now.

not the most walk thru user friendly but boy this one is powerful! great paired with obdlink mx+

Just downloaded and ran two service regens on 17 Cruze TD using an obdlink mx+. Works great.

This needs a trial for 30 bucks a year. It didn't do more than what I could accomplish with torque outside of accurate tpms sensors. The gear is incorrect, the gas milage is in l/h, you can't use torque widgets with this. Overall, definitely not worth 30/year. I'm very much willing to pay 30/year for torque looks and all gm pids. This isn't that.

This App is a scam. Everytime I try to get a read or do a regenerate it lost network connection and lost connection to the module. DO NOT BUY.

I emailed the developer a couple questions regarding my intent to use this app to force my diesel Chevy Colorado to regenerate the DPF. I have very basic knowledge of this stuff and Justin patiently and thoroughly answered my questions even though I emailed him on a Sunday. Bottom line is, I was able to force a regen on my truck and monitor the progress easily. I have had to pay for this to be done by a mechanic three times this year. This app will definitely save me money. Thanks!

Replaced my DEF tank heater in my 2015 Duramax but struggled to clear the "service DEF system" warning. Needed to initiate all 3 DEF heaters before the truck would kill the impending speed restriction. My current scan tool wasn't able to command each heater on, but this tool certainly did! I have is a ELM327 BT adapter, but like others have said, its too slow to stay connected reliably but it stayed on long enough to run all 3 commands. Ordering a MX+ today. Best $20 I have spent in a while. TY

Changed NOX sensor had level 5 code. Ran reductant fluid quality test and cleared the issue. Used obdlink mx+ no issues.
