iWord in this July 14, 2007 listing was a dictionary-search web app at idotg.com/apps/iword.php. The archived description presents a straightforward iPhone interface for looking up words.
The name should not be confused with a word processor or a later document-editing product. This historical reconstruction does not verify that the original web service still operates.
Begin with the question behind the word
A dictionary lookup can serve several purposes: checking meaning, resolving a spelling doubt or deciding whether a word fits a sentence. Knowing which question you are asking helps you judge the result rather than treating any returned entry as a complete answer.
The surviving iWord description does not identify its dictionary database, audio features or offline behavior. Those remain undocumented, even though another dictionary app might offer them.
Bring the sentence with you
When a word has several meanings, keep the surrounding sentence available. A definition that makes sense in isolation may not fit the grammar or subject of the original passage.
For writing, try the proposed word in the actual sentence and read it aloud. The task is to express the intended meaning clearly, not simply to replace a common word with a longer one. A lookup tool is most helpful when its result returns you to that task.
A focused web utility
The old app’s narrow scope is part of its historical interest. It tried to reduce the steps between encountering an unfamiliar word and consulting a reference on the phone already in hand.
For present-day app comparisons, test that same sequence: enter the word, understand the result and get back to what you were reading or writing. A large collection of unrelated features may be less useful than a clear path through those three actions.
This restored address preserves the original iWord identity through its dictionary purpose and idotg.com destination. It does not imply that a current product sharing the name is the same service or a successor to it.
