I've been using this app for the last couple months and it's been instrumental in understanding how my 2012 HyCam works and reassuring me that all seems fine since I bought it used 8 months ago. Anytime I drive without it I feel 'blind'
The Dr. Prius app recommends the Panlong OBDII, so I'm hoping that will also work with Hybrid Assistant...
I've been using it for a couple of days and you can absolutely have other bluetooth stuff running at the same time as Hybrid Assistant...
