Bluetooth OBD2 dongles are relatively new to the automotive world but do work well once they are understood, mainly the app used.
The most popular app is called Torque but there are many more available free and paid.
Personally I use which ever app is free since all I need them to do is scan for the code and clear it if necessary, most any OBD app will do this.
The paid versions do come with more features if that is needed such as monitoring oil pressure, temperature, and other engine vitals in real time.
Below are some units we have used and have worked well.
