⭐⭐⭐⭐ (4/5) OBD Fusion is an excellent technical diagnostic app for monitoring my 2008 Toyota Prius, paired via a Veepeak OBDCheck BLE. It can be finicky to connect if booted in the wrong sequence. It has a steep learning curve and a complex interface. Tracking hybrid data points like block voltages or inverter temps requires a paid "Enhanced Diagnostics" add-on. Still, as a scientist, I find the unlocked tracking resolution and logging granularity to be an excellent analytical value!

this app is identical to OBDLink that comes with your Bluetooth OBD Link interface . Don't bother

I'm using a cheap little plug in to the OBD connector called Dicknos Elm327 mini Bluetooth that I got for 8 bucks from Amazon for two of them and it works better than any other cheap scanner it's a 100% upgrade because now I can monitor the cooling temperature sensor the O2 readings the maff and map readings as well as the catalyst and the EVAP system while all the car is running and it's accurate great app it was worth the $5 thank you

Absolutely love this app. Highly configurable plus you can view the data on CarPlay. The developer is responsive to emails and suggestions, and may just offer to add features to meet your specific needs. Do yourself a favour and take a look at it.

Best overall for my use
Ive tried all of them. I have a 2024 Toyota and whilst it’s not listed they have the same model as a 2021 which is when my model changed. I paid extra for the Toyota enhancement diagnostics and everything was listed and ready. Simple clear readouts and not overwhelming to change the gauges etc. I wish I knew about this before any previous purchases. Make sure you have one of their supported adapters. I use the Kiwi3. I’ve never written a review so I felt compelled after this. Yes it costs money. Yes the enhancements for certain models cost money. But you get what you pay for and there seems to be regular support on updates for this app unlike many others I highly recommend it. I’ve deleted all the other apps like dash command that was just a pain to setup nicely but that’s just me

Deceitful. $15 gets you a toy app. Then pay WAY more for anything useful.
Just another dodgy business model to access your wallet. Do yourself a favour - just head STRAIGHT to CAR SCANNER PRO and download that - FAR superior to this. You figure the $15 download fee will give you enhanced diagnostics.. only to find it gets you almost nothing - just the simplistic app with nothing advanced to fix your car with. Pay much more for those as ‘options’, and that’s IF your car is supported, which mine wasn’t. So I just wasted $15. That’s a big zero from me. For the win: just get the FANTASTIC Car Scanner Pro app.
