Works slow but always connects. Also it is somewhat limited in the data it recognizes. ### 2/5 — Limited dashboard-functionality *2018-06-02, version 2.0* - There are only the 2 dashboards shown in the application store, no more - Dashboards are not customisable - Fuel %, range etc. not supported by cars we have tested it with (Suzuki) - values show nil - Cannot set unit of measure (i.e. shows mph as unit of measure but value is km/h). There is no settings at all other than to set if you are using a WiFi or Bluetooth adapter Depending on your priorities, if you want live stats displayed on a well designed dashboard, this application would probably disappoint. The screenshots in the application description looked promising, unfortunately there is no more than that. I have not looked into the diagnosis functionality yet, that in turn may be satisfying (my cars are not showing faults yet). --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
