There is an interesting app called *AF Manager* in the App Store which is free. I don’t know whether it is available for Android. It is basically for professionals working with AF patients and so is quite technical. It’s produced by the European Association of Cardiology. It contains lots of information about AF and, particularly, information on what options are available and are to be considered when a patient presents with particular symptoms. It would certainly be useful for someone who is having problems with a particular medication and wants to know what the options are. Worth downloading.
