Pros and cons of OBD Fusion app for iPhone and iPad

OBD Fusion app good for

After much thought with regards to the competition I settled on obdfusion. Pleased so far, easy to use and reasonably intuitive app with lots of eye candy with regards to gauges. Dashboards are very configurable. Complaints about not being able to connect to bluetooth ELM modules has absolutely NOTHING to do with the app - theyre not compatible with the iPhone so NO OBD software will work with them! People dont read before buying!
I am using this app for measuring the speed of the vehicle. Apart from the occasional connection drops the app is functioning well. The setup was very easy and the interface is easy to use.
I reluctantly purchased OBD Fusion really to see if it could surpass my suite of vendor specific OBD tools. Well it has. When it comes down to diagnosing engine issues, be it on a Ford, BMW or Aston Martin- I inevitably turn to OBD Fusion for its ease of use and in depth analysis ability. Well worth the price and likely the best value item in my toolbox.
Thank you very much for app!!! Please, update language pack Russian. Очень хочется на Русском языке.
Shows you whats happening live and in person. Needs to be able to display on the Sync console in Fords. Doesnt seem to like music to play over blue tooth or cable at the same time.
The user interface is superior to similar OBDII apps that Ive tried. The information supplied is much more detailed as well. Excellent!

Some bad moments

My car malfunctions every time i try to connect it. All dash lights come on and the car shuts off. Very scarey. Im done trying to connect this this app. What a waste of $10
Read the reviews and went to the supported hardware and then the FAQ. Some customers had the scanner I had and said it worked so I gave it a try. It didnt, and about four hours later I tried to return it. Response? This app is not returnable. They should be ashamed.....
Right now it gets a 2 star rating because it will not stay connected for me.
Honestly this app didnt work for me it crashed and didnt allow me to add Bluetooth but after that it would be crashing during the process later when I closed the app it wouldnt open I would give 0 stars but cant
the part you can use on the apple watch is not worth the money
User friendly. Only problem i have is getting obd2 mode and pid for lexus. No info for my lexus
