This Is the free app that accompanies the company's (expensive) hardware. However, I was pleasantly surprised. It does everything that it says, i.e. fuel efficiency, tach, sensors, all of it on your iPhone. However, the hardware did charge my iPad 2 nor could I use the app on my iPad. GoPoint does not advertise or claim that they do, but I thought it important to mention since iCloud will automatically bring the app to your iPad too.
Overall, a promising product and I hope they expand on its functionality.
