I have previously tried others but found this one to be the most reliable. The program is so quick, easy & intuitive, no Help screen is needed or offered.
Cons
There are Zero Cons to speak of. However, simply as a token of professionalism, the app ought to offer an "About" screen (which displays, for example, the Version Number & the author's homepage).
