Amazing software, and fantastic customer service. I was able to rule out my hybrid battery as the culprit for my reduced mpg. Initially the app wouldn't process my payment but I was able to quickly resolve it through the customer support email. You just gotta read the obd II compatibility section in the app to find a cheap one that'll work with the app. Incredibly intuitive and saving me so much money and worry.

The battery monitoring screen is confusing because it self adjusts vertical span... versus a fixed voltage range. For me (a EE) I'd get more out of it if it were fixed range of maybe 0.5v/block vertical span. Still auto-center the scale, but don't auto-change the vertical voltage span. It would be a great user option... Fully Auto-scale, or Sliding Fixed-Scale. It would also help to filter the values a little, there's way too much screen activity. Again, this would be a great user setting.

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.
