Improving problematic app but audio useful.

App Buyer9

Oflline audio guide is good although fairly low-quality recordings with some muffled sound.
With iOS8 upon us, this app looks incredibly dated -now improved (I've added one more star).
By default the search box shows a(1) meaning you have to delete that text to empty the search field first everytime - now finally removed, mind this took months and months just to remove one tiny thing that made the app cumbersome.
No thesaurus.
The favourites section could be beefed up with alphabetical sort options, perhaps some review and test opion, and most usefully: a full-screen table view of word favourites not just one single narrow column.
New problems:
Got rid of the side column which is a terrible idea. Here's why: if I type a prefix the column showed a list of possible words and I may want to read several definitions. By removing the column it forces you to lose your 'place in the book.' It is the same if you press the wrong word, you cannot then correct yourself but have to go back. Far better would be the user-option to open and close the side column at will.
The favourited words are now out of sync with definitions! My 'pariah' now shows definition for 'ariah dog', 'teratology' shows defn for 'teratoma', 'parsimony' shows 'parsley', 'segue' shows 'Sedgwick, Adam', etc. Hundreds of fav words are now all out of sync!
Nag, nag, nag, rate me, rate me, rate me pop-ups the app...correspondingly I’ve knocked a few stars off.

Disappearing definitions and annoying colours


(Saying all this, this is still my most used dictionary app and I won’t get rid of it.)

I generally like the dictionary, which has a good range of entries and useful derivations on the whole. However, the new colour scheme is annoying. I liked it when it tied in with the colours of the actual hardback dictionary.
Additionally, there seem to be definitions missing from the previous update. For example, there is a definition of “again”, which means “in response to; as a result”, which is no longer there (but is in the Shorter Oxford, so all is not lost).
Further, the interface for entering a new word is clumsier than it used to be and there are now added taps needed to navigate or to just search for a new word. This could do with some work.

I have used for Study, Work and for saving personal documents it had helped me saving money and worry free.
This application with an Office Suite has greatest use benefit for beginners and Students. The biggest savings you will get on an Ipad-Pro in making One time purchase only. It means that Microsoft do not have power to excuse subscription and steal money from individuals resisting uncertainties, just because you want to use Apple device for experience Virus free work.
