Zarf is a multipurpose utility for Scrabble® players in any language. It provides word list lookup, pattern matching, tournament-style adjudication and a timer customized for tournament Scrabble® play.

Use the Search panel to perform pattern matches, anagrams and builds to find legal words in one of five built-in word lists, or in word lists that you can download to your device. Tap on a word in the word list to bring up a list of hooks or look up the word's definition on the internet.

Clabberware does not provide downloadable word lists, but they're easy for third parties to publish, and they can be found with a little web-searching.

The Judge panel can be used to adjudicate tournament-style challenges in Scrabble®. Enter one or more words and the play will be ruled acceptable or unacceptable.

The Clock panel displays a digital countdown timer ideal for Scrabble® use. An indicator lights up when courtesy hold time has expired, as required in tournaments. Challenge buttons are available to automatically pause the timer and adjudicate in-game challenges.

Needs Updating

One of my favorite apps, until it stopped working when I updated to iOS 11 today. Please fix! Charge a few dollars if you have to!

Zarf needs to be updated

I love using Zarf. I play a lot of Scrabble and its so helpful. It's helped me become a better Scalable player. My only criticism is that it needs to be updated. I have the latest operating system on my iPhone 6 and after one or two lookups, it crashes and pops me out of the program. I hope you will fix it soon!

Great Scrabble toolbox!

This app is superb. Powerful features. A must for serious Scrabble players. An all in one tool box. I especially like the front and back end letter hooks - unique and extremely helpful. I use the app just for that a lot.

Anyone who rated this one star is clueless and made a mistake - can't read directions or whatever. User error.
