I have been using this VERY useful app and have always received a fast and courteous reply to any queries from the developer. There may be other apps out there that do the same thing but stability and longevity are worth more than dollars.
You will also notice that the developer has completely re-written the app and hasn't asked for more money from the people who already own it.
I think its a bit scathing to rate this app as adequate without giving the new, rewritten app a thorough try.
Careless remarks sometimes costs money. For my book, it does what I want, has done for years and has never once crashed.
In my book, that deserves top marks.
