Easy and Functional The customization feature is awesome. Worth the price of admission. Which means to get the app fully functional, you need to buy a subscription. Still cheaper than going to the dealer to have them do the same thing and charge each time you want to try a new setting. Very happy, we have three Toyota's in our family, all are customizable.

The app works fine for scanning the modules of my 2017 VW Passat. I did the trial upgrade to the 'Pro' version so that I could make some changes, then cancelled my subscription. This app is definitely NOT worth $40 per year for the minimal amount of programming options given. A plus+ is that it worked with my cheap ELM327 bluetooth adapter. Since this is lacking extended coding options, the subscription service is overpriced and really a non-competitor to OBDeleven and other 'more powerful' tools. I see no reason to pay indefinitely for it's limited ability. If anything, the subscription service should be considered a R&D fee. It has potential, but I just don't see the value at this point.

I get it, I really do, to keep an app running, they need money. However, it used to be free just to SEE the trouble codes. I didn't mind it when they required me to pay to reset the codes or do other extra stuff, but now I have to pay to do a basic function (which, might I add, takes forever to load all the codes)? No, no more. This reminds me way too much of Gameloft. I'm ditching this tool and buying a dedicated scanner that doesn't need a cash-cow app. It was good while it lasted. EDIT: Nice try, Carista, but that isn't true. It hasn't always been a paid-for feature to SEE codes. I used this app for two years, and I could see codes just fine without a subscription until now. If you're going to try to deceive people, at least make it believable. I'm never returning to this sketchy brand. Buyer beware!

Hi Jakob, thanks for your review. Seeing and resetting standard OBD2 fault codes has always been free (and still is). Seeing and resetting manufacturer-specific fault codes has always been paid. Nothing has changed in that respect; maybe you just happened to have standard codes before. If you liked the functionality, pls rate accordingly. Thanks!
