I already have automated scripts running at home that download the daily data and generate basic reports for me so I have no need to spend $20 on an app that I can't even see what it does.
I'd be interested to know how Sales App and the new one about to come out, as mentioned above, deals with the fact that Apple makes changes to the pages for downloading the sales reports every once in a while.
BTW - My scripts for downloading the data can be found here:

These are NOT supported. It also seems that some users from some countries other than the USA get a different screen or two so this script may not work for you but I use it every day. It's set up on a Linux server I have as a cron job.
