Not practical
This is not helpful for everyday use when learning te reo. For most searches, far too many results come up, many of which are irrelevant. There’s nothing to indicate which is likely to be the most applicable. For example, a search for “dirty” brings up 19 results. Search results sometimes don’t include the most obvious word. For example, a search for “cook” does not bring up “tunu”. This App seems designed for academics and not for those trying to learn the language and to use it in their lives. A Google search is usually more helpful. Also there’s no ability to easily go back to your previous search. You either need to type it in again or exit and then re enter the App to see it in your recent search history.
