I found this application to work well, and easily expose letter combinations in an intuitive way. It took me a little while to realize that the Wordipus settings page was actually on the iPhones settings page (perhaps this could be made more apparent from within the Wordidpus app itself?). But after I found that, it was smooth sailing. I like how you can configure the settings to limit what you see, which makes it more relevant to what its being used for (Scrabble in my case). Anyways, awesome app!
