ULU is a word-lookup and tournament adjudication tool designed for word games such as Scrabble, Words With Friends, and crossword puzzles. Developed by Revolutionary Apps LLC, ULU is available for free on iPhone.

One of the standout features of ULU is its extensive lexicons. It includes both the NWL2023 lexicon for North America and the CSW2022 lexicon for the rest of the world, making it a versatile tool for players worldwide.

The Search page in ULU allows users to find words that match specific letter combinations, with or without blanks and wildcards. It also enables users to search for words that match specific patterns, contain only a subset of letters, or have a certain length. The search results can be tailored to show only the number of matches or to highlight the blanks that make matches. Tapping on a word provides more detailed information about that word.

For tournament Scrabble players, ULU's Judge page is a valuable feature. It allows users to quickly determine the validity of words they type, ensuring fair gameplay.

Additionally, ULU includes a customizable timer, making it suitable for use in tournament Scrabble or other games that require time management.
