Pros: Easy to set up, easy to use, clear instructions on the battery test, clear results on screen that explain the condition of the battery. Cons: You can only use the personal licence 3 times for $11.99+tax, gave me an error message when trying to save my results. I feel it's a bit overpriced for something you can only use 3 times. They have a mechanic version that costs $30+ which they should rename as Unlimited. They should change the personal to 5 uses or add more pricing tiers.

This app is so easy to use with any Prius! Just be sure you have the right OBD2 adapter. This app tells you which one to buy, too! You can find your error codes and reset them too, even while driving. This is useful when your HV battery is starting to fail until your new one comes in. You can also disable the annoying reverse bus noise and seat belt beeping.

Wow! Provides a nice view of real time voltage of each block. If you hit the record button, it will capture voltage and internal resistance of each block, MPH, Amps being charged/discharged, and SOC every second. When you click the record button again, it will allow you to share the log as a csv file to email, etc. If you open the csv file in excel, you can get a real good idea of how each of the cells perform. You can also read and clear OBD2 codes. This app is accurate and essential.
