I have had a OBDII unit in the 08 Gen II Prius, ordered from Amazon in 2012,
PLX Devices Kiwi 2+ Bluetooth OBD Car to Smartphone Wireless Link and Scan Tool for Android, Windows, Symbian, Linux and N9 it worked really flawlessly!

In the Leaf I had to buy a different one, the first would not talk to my Iphone. It was a really good one..also ordered from Amazon in 2016.

Now in the KIA Niro I had to purchase a third unit, because the second unit would not work in the KIA. It's also from Amazon ordered a month ago...12/2017

It works terrific with Torque! And it's small!

Go figure.
The first one was Wifi, and the other two were Bluetooth

I use a Palmer Performance bluetooth obdll. Go-point. Cost was 180; 8years ago. Worked flawlessly on all other vehicles, not this 2007 prius yet, combo meter problem in a new thread.
Recent update has a screen orientation bug, but this is the only issue in all of the years of use.
Dashboards are great, guage options are nice and plenty of pid's.
Prius real-time view is available for me to veiw, just not the DTC's-combo meter connection I am guessing...

 

First one I got was the BAFX Android Bluetooth Wireless OBDII Reader & Scan Tool - For Android Devices Only. It sort of worked for Torque, but not very well for Hybrid Assistant. It would often have trouble reconnecting between startups and wasn't reporting all the relevant data for Hybrid Assistant.

Then I switched to the OBDLink® LX Bluetooth. It was more expensive, but has worked nearly flawless for both apps. I would definitely recommend it if you want to have real-time updates from your car while driving.

 

Did you use obdlink with Dr Pruis? How did it work as far as hv health?

 

I use this $28 version with Dr Prius. The hv health functions seem to be reasonably accurate. It won’t fix a bad hv battery but the load test algorithm seems solid. One use tip: Disconnect other bluetooth devices the phone or tablet may be connected to ensure good results. Otherwise I am able to leave the adapter on the car without concern.

 

I bought one of the cheap $7 elm327 BT V2.1 from USA Warehouse (ebay). I planned to use it with my Samsung Note phone.

I purchased the Torque Pro app and downloaded the gen 3 PID's. It seemed to return data from parameters that I created objects for from the ECM but not other ecu's like voltage or resistance from the traction battery.

I spent a few hours with it but I didn't try it with another phone/tablet so I couldn't say whether it was my phone or the BT adapter. I have since switched back to my ScanGauge and have been busy with other things and have not gotten back to it.

 

Dr Prius and Car Scanner free apps will get the battery data.

 

The TorquePro app has objects for cell voltage and resistance in the Prius Gen3 library but they just didn't work. I created one page that was the 14 cell voltage digital displays and a second page that was the 14 internal resistance digital readouts but I got no data with them. Parameters like RPM or engine temperature work but battery data didn't. Next time I swap out the ScanGauge for the Elm327 adapter I will try the apps you suggested.

 

The Dr Prius app has recommended obd2 bluetooth scanners that have been tested. The attached pdf is a snapshot of some of my v's battery points using car scanner last year. The link shows various Dr. Prius screens.

I can't agree with that list from the Dr Prius app.

New OBD2 Bluetooth Adapter is better than Carista -

I love the dr prius app but Carista shouldn't be bought and the $100 adapter I purchased has shown me more information on my car than other adapters. Heck, once I'm done with this tank of gas, the adapter I have could've made Hybrid Assistant report data more accurately...
