Free version used to allow codes reset. Other free apps allow that and sensor data. Free functions very limited. Pro functions have potential. Without evaluating them on the free version it would be difficult to judge its performance. U could be losing paid upgraders for that. The connection process is slow and disconnects too easily and often and not easily reconnected. Having some way of trying the higher functions before buying and fixing the connection issues Would rate this higher. The main plus is its clear drive cycle tests section.
