I do not know if it is a problem with the unit or just the app. Either way it is annoying. ### 1/5 — Charged money for no reason *2026-07-22, version 7.4.0* Charged money for no reason ### 5/5 — Great App *2026-07-12, version 7.3.0* I like to monitor vehicle sensors and this App delivers! ### 1/5 — Paid app but then you pay again in app *2026-06-30* Yeah first you pay it to download then buy enhanced pack if you want to see all the sensors. I mean I downloaded car scanner and it have more features as a free app. I can’t see my atf temperature in fusion but in car scanner I can. So I unlocked the lifetime option in car scanner rather paying this developer. Sorry I paid for half the features and this should be highlighted first not later. Not asking for refund, you can keep it. ### 5/5 — 20FuZion *2026-06-25, version 7.3.0* New to the App, just a dashboard so far, but really looking forward to digging deeper. So much in there & for any future code diagnosis. Took a few tries to get it to talk to iOS, but managed. ### 2/5 — No Dashboard CarPlay integration *2026-06-24, version 7.3.0* The app haves a lot of configuration tools and great dashboards, however it is not worth the purchase as the Apple CarPlay integration is terrible. You cannot monitor the information setup in dashboards with Apple CarPlay and that makes this a 2 star purchase. If the app had dashboard display for CarPlay, it would be well worth the $10 purchase price. ### 5/5 — Really cool app for iPhone *2026-06-18, version 7.3.0* This is a really cool app for iPhone. It works well other apps charge you by the week or a ridiculous yearly price. This app was cheap one time fee and works great. ### 5/5 — Love it *2026-06-12, version 7.3.0* Use it each time I drive my LS swapped C10 ### 1/5 — Not for iPhone *2026-06-06, version 7.3.0* Works great on android but very fussy on iPhone so it’s unusable to me. Wasted my $ ## Frequently asked questions about OBD Fusion ### What does OBD Fusion do? OBD Fusion is a mobile application that connects to your car's OBD2 port using a compatible adapter.
