Tried different Bluetooth devices and never worked. ### 4/5 — The app works *2023-01-31, version 1.3.2* It works on my BMW F30, except that the live data is a snap short and is not continuously live , you need to refresh but generally it works, I simulated a fault by removing the Mass air flow sensor, it showed P0100. I give it 4stars ### 1/5 — Uzak durun *2022-12-11, version 1.3.2* Deneme fırsatı vermeden para istiyor. Çöp ### 1/5 — SCAM!! stay away *2022-11-30, version 1.3.2* Let’s you pay for the subscription even though the app holds you on the payment screen. Do not buy! Doesn’t work ### 2/5 — Had to buy feature. But doesn’t record anything *2022-11-14, version 1.3.2* Bought it so I can track diagnostics and sensor values, but doesn’t let you record values to a file, and doesn’t show the errors on my dashboard (which I know there are) and other free apps do show them including official dealers. Very basic app, and the paid features you can get for free on other apps on the App Store. ### 1/5 — Not compatible with Kiwi 3 *2022-10-17, version 1.3.2* Does not work with my Kiwi 3, always shows as “not an adapter” when I try to connect. I sure with I could get a refund after paying for the in-app unlocking if that feature… ### 1/5 — Worthless without paying first *2022-07-12, version 1.3.2* Hi. I download this app to test my OBD II Scanner, but it’s worthless unless you pay for it. A much more honest company would charge a few bucks for a working app. This tricks you into thinking at least basic features would be available. Well, I have the perfect solution. I’m deleting it now Try DashCmd. It’s a good app, well when it works. My WiFi shows the scanner but nothing connects. Remember back a while when there were actually honest companies? This guy doesn’t seem very honest or it would state right up front a payment is required, but he’s right, I would have never downloaded an app that’s broken before you can even test or use it. If it were any good, you’d be able to easily see that in a working app. A basic connection and even basic info to prove it works and is worth the investment, seems like it be a much better app. This just wasted my time, so I complimented the dishonesty with a fair review ### 1/5 — Rubbish *2022-07-05, version 1.3.2* Don’t buy it can’t understand anything ### 1/5 — Nul *2022-07-02, version 1.3.2* Nul ### 1/5 — Does Not Work With Adapter *2022-05-31, version 1.3.2* Save your money and look elsewhere. Waste of $2.99 🙄 ### 1/5 — Nul *2022-05-05, version 1.3.2* Téléchargement payant qui ne sert à rien ne marche pas ### 1/5 — Pay only *2022-02-10, version 1.3.2* Doesn’t do anything unless you pay ### 1/5 — Not as useful as some free versions *2022-02-01, version 1.3.2* Needs work ## Most critical reviews (10 lowest-rated) ### 1/5 — Bas buy *2025-06-26, version 1.3.2* Always disconnect ### 1/5 — Stuck at “loading services” forever *2025-02-13, version 1.3.2* Somehow it keeps scanning for tens of bluetooth devices around me, instead of allowing me to simple pick the obd one, and it keeps “scanning services” forever, I waited for longer than 20 minutes for nothing ### 1/5 — Does not read trouble codes *2024-11-12, version 1.3.2* Purchased the OBD2 app to scan trouble codes. I hooked it up to an Elm Wi-Fi adapter, got it connected, but does not seem to read any codes or do anything beyond identify the vehicle. No settings or instructions. I purchased it as I thought it could read and clear codes. It does less than free apps currently. Maybe I’m missing something. ### 1/5 — Don’t waste your time & money!! *2023-11-30, version 1.3.2* I downloaded the app, paid for the complete app and the only thing the app does is “identifying..” my OBD tool that is clearly shown when you try and connect! Closed the app 5 times and the same thing every time, identifying but never connecting! ### 1/5 — Müll *2023-08-27, version 1.3.2* Nutzloses Zeug ### 1/5 — App *2023-08-08, version 1.3.2* Die app ist völliger Müll. Hab 4 € bezahlt damit ich die OBD2 Funktionen auslesen kann. Also nur Motor. Das geht auch mit kostenloser Software. Nucht empfehlenswert ### 1/5 — Scam *2023-07-05, version 1.3.2* Apple please do something about this ### 1/5 — Nutzlos *2023-04-20, version 1.3.2* Selbst zum Testen ob zum Dongle überhaupt eine Verbindung aufgebaut werden kann muss bezahlt werden. Ob es dann auch funktioniert ist fraglich. ### 1/5 — Obd expert *2023-03-18, version 1.3.2* This is completely rubbish i want t refund this purchase its useless and trying to connect to other people and discuss solution ### 1/5 — Pessima app *2023-02-08, version 1.3.2* Pessima app o spendi o non la usi morale cene sono altre di migliori saluti ## Most praised reviews (10 highest-rated) ### 5/5 — Audi a3 quatre sport Line *2024-12-30, version 1.3.2* Introuvable ### 5/5 — Top *2023-11-10, version 1.3.2* Coole Software funktioniert bei meinem e46 super und schnell ### 5/5 — Thanks *2023-02-22, version 1.3.2* Thanks ### 5/5 — Bbva *2023-02-21, version 1.3.2* Bien ### 5/5 — La mejor aplicación *2022-06-01, version 1.3.2* Muy buena cómoda y agradable ### 5/5 — A++ *2022-02-22, version 1.3.2* Works like a charm.
