Dr. Prius app

Every time I start my Prius up and drive down the road, it discharges the battery from full bars down to two bars and then charges back up. I downloaded the Dr. Prius app and used it with my Bluetooth OBDII adapter. Here is the information I'm getting. I want to do the battery tests, but I need to buy it. In y'all's experience, what is the price for the unlimited vs the three car test? And does the three car test allow you to test three cars unlimited amount of times? (I have three Prius.)
