Not worth the price. This app have some fixed gauges which read well. The PID (choose your own gauge) are too tiny. The code reader shows codes that don't make since for my car even with correct protocol set and no codes where stored anyways. Shouldn't have shown any. One of two emails where answered.
Works but... Can't read the name of each dial. The text is centered so that all letters in each label are at bottom center of each dial layered on top of each other within the space of a single character.
