Analyzed automatically. Assessed 2026-10-04 from 410 user reviews, the store listing and its privacy label. We have not scanned the app's package, so nothing on this page was read from inside the app itself.
This analysis describes version 10.0 of the app, analyzed 2026-10-04 . The app may have changed since.
The store currently lists version 10.0, updated 2026-08-21.
What the analysis found
Positive evidence 1
Things this app does right, published at the same strengths as the catch list.
One source only — shown, not confirmed 2
A single kind of evidence. We publish these because withholding them would be the bigger distortion, and we do not treat any of them as a finding we stand behind.
What reviewers said
Verbatim excerpts from public store reviews, shown as corroborating user reports. They are not Appworthy audit evidence, and a quotation is not proof of the finding it sits under.
Paywall blocks the basics
Had to purchase a subscription to check whether a feature was available for my car. It was not. I canceled the subscription instantly and asked for a refund which was declined by the developer. That is a really unfortunate behavior in my…
gets more expensive yet half the customise features still don't work. Now they have even locked more diagnostics behind the pay wall and upped the price by 50% with no new working benefits to justify it. The amount of times it has…
I bought the Carista OBD2 reader years ago, from day one it had all the features available, including checking faults. Now you need to pay a monthly fee just to be able to use the basic features of an OBD2? Thats ridiculous.
Reports that the ads misrepresent the app
Useful features as far as I've seen so far but beware the free trial period, there isn't one and a subscription for 12 months gets taken out immediately the same day you start the "trial". Disappointed with this false advertising…
I bought the Carista OBD2 adapter and a subscription about 2 years ago. I unlocked some features on my Toyota and canceled the subscription. Now that I have a different car, I checked for compatibility and it said I could unlock features…
bait and switch. purchased the hardware, then to actually use it I have to pay a lot of money for an app subscription. looking to return my carista device, but they refuse. legitimately stole my money among many others. I expect a class…

How the automated analysis works
This assessment is produced automatically. Three independent signals are read — user reviews, the store listing and the store privacy disclosure — and each candidate finding is filed under the sources that support it.
No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every subscription bills weekly; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.
There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.
Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.
Several measurements above say “Not assessed” because no artefact we hold can answer them. A human review is what resolves those — and it can remove a favourable band as easily as add one.
Hands-on inspections are not yet open.
