Thanks for a wonderful gift

Thank you Seth.

I love this App

It’s definitely helped me learn new words and new anagrams. I don’t know why but my iPad version won’t give me definitions. I’d pay for this app, just saying. I love tournament scrabble and I am improving yearly with study. This tool really helps.

It’s tricky knowing what the word lists are, the abbreviations are confusing. Updating the app description here in the App Store would be nice — add latest lists and describe what they mean. For instance, the latest NASPA list has two for 2020. The one with the S is for school or students and has more ‘objectionable’ words removed.

Thanks for such a handy tool!

Works for Me

Albeit, this App has a couple of drawbacks when compared to Zarf which, to many, was the Gold Standard. However, ULU is more than I could have hoped for and, for our purposes (wife and I), it is exactly what we needed when we go head to head in our Scrabble competitions against each other. Thank you for developing this wonderful App.

Lives up to its name

The only other feature I wish it had was definitions, but get that this a licensing issue or whatever. Thanks for an exceptionally useful tool, Seth!
