Carista may be a scam!

I hate to say this, but either their programming is really bad or it is a scam.

In mid-March, I bought the Carista Pro app ($20) and the Carista OBD module ($40). I used it to change one seatbelt warning but my main interest was in using it to register TPMS sensors for changing between sets of wheels with OEM and snow tires on them. I heard that this capability was under development at Carista, so when they offered me the opportunity to get the Beta test version I downloaded it. The TPMS capability was there and looked fine, so I figured I was all set. I knew that the Beta would expire in a month or so and just figured I would be shifted to the updated Pro version at that point.

A couple of weeks ago I tried to use Carista and it kept shunting me to the Apple Store. Today I tried a bit more and discovered that they wanted to charge me ANOTHER $7 for a week of access to this app, which I had already paid for, or $40 for a year of access. In the meantime, they sent me an invitation to download another Beta, this one good for 60 days.

So either they are lousy at tracking who has already bought the Pro version, or they are trying to scam regular payments to use their app. If you look at the reviews on the App Store by opening iTunes, you will see that others have had the same problem for example:

"Don’t Purchase this or the device. Multiple payment scam.

Found this app/device combo after researching Service Reset options on Audis. I liked that the app and the obd device were from the same company, and would work together, so I didn’t mind paying a little more. I didn’t realize how much though. After purchasing the Pro option, I had to scour the internet to find out you have contact the developer to request the Beta version which ‘unlocks’ the main features. First this is shifty. They are gaming apple. Second I had no response to multiple emails and FB messages until I suggested I’d start discussing my negative experiences online. Now I have the Beta (you have to install it through another app- TestFlight) which only lasts for 30 days. When I ran the test and tried to reset the service warning I’m told I have to pay either seven dollars for a weeks access or forty for a year for that feature. This is after I’ve purchased the overpriced device and paid for the “full” pro version. They also make you pay overtime you unlock the ebrake. I feel duped for having bought into the idea that I’d be treated better with a company offering the whole package. I thought I’d save time and money by avoiding the Dealership, but in this case I’ve wasted both and I’d give my seventy dollars to the dealer crooks rather than these scammers."

So I don't know if I can use it to do what I want to do this winter.

I apologize for recommending Carista here.
