Veepeak OBDCheck BLE Bluetooth OBD II Scanner for iOS & Android, Car Wireless Check Engine Light Code Reader Diagnostic Tool

This tested well with several cars and a hybrid with good connectivity and comprehensive functionality. It isn't the cheapest model out there but it seems to be worth the price.

Bought this a year back while on sale, knowing that I'd need this eventually. Plugs right in the OBD2 port on my 2008 Honda Accord EX and works perfectly with Car Scanner ELM327 (aka Car Scanner Pro) on my iPhone 14 Pro Max. I'm able to verify all the sensors, check existing codes, clear codes/check engine light, and monitor other stuff like fuel mileage. This works perfectly; just remember to connect from the app and not your Bluetooth settings! I'll also try this with my iPad as I'm sure the extra screen real estate will make the app even better.

Great product! Worked perfectly on my 2013 Toyota Tacoma TRD v6. Used to monitor atf temps for trans fluid drain/fill. Great value for all the metrics you get with this device and the free car scanner app. Wish i knew about this device sooner!

Works very well on the cars I tested, just needs application with it; the connection is okay.

This is a really handy tool to have, especially if you want a portable way to read and clear check engine codes, view live sensor data, and monitor performance from your phone. It works with both iOS and Android when paired with a compatible app like Torque, Car Scanner ELM OBD2, or OBD Fusion. It’s compact and easy to install in your car’s OBD II port, and once you’re in a supported app you can see things like engine RPM, coolant temp, trouble codes, and more — great for basic diagnostics and insight into what’s going on under the hood. A few practical things to know before you buy: • On iOS, you connect directly in the app rather than through the Bluetooth settings. • The actual features you get depend on the app you choose — some advanced diagnostics require a paid app or certain apps that support your vehicle. • Compatibility with Android head units is more limited than with phones due to Bluetooth profile support. Overall it’s good value for money — easy to use, small enough to keep in the car, and it gives useful diagnostic data when paired with a quality app. Just make sure to check which apps you plan to use and whether your specific vehicle supports the functions you want before relying on it for deeper diagnostics.

Works great with my iPhone 16Pro running iOS 26.3 and 26.2.1. Just used this morning with Carista app on iPhone customizing my 4Runner settings. Haven’t tried on iPad yet. One app took a long time to connect but finally did “car scanner elm obd2”. Not sure why though. But it works great after it connects and lots of customization abilities in free version, surprising! But great.

Easy setup and connection to the CarScanner app on my iPhone. It's good to be able to check the health of individual cells in the drive battery of my 2024 Ioniq 5 SEL as well as many other health checks. An older OBD II scanner I have was not compatible with the Ioniq, so this was a good upgrade.

My second unit. I had one for my JKU. Now have a Gladiator. Works great. Way cheaper and easier to operate than the tazer ones.
