I actually really do love this app, and I very rarely rate apps!!! This app is easy to use, easy to understand & is just overall user friendly.

With that being said, I only gave it 4 stars. This is because like others have also said, I wish it was slightly more sophisticated so that when I go back to the main page it doesn't bring me all the way back to the very top, so I have to scroll through everything I've already read. I also wish that for the Idiom of The Day that the video provided more information, instead of just simply repeating what is already written about it. Like the one reviewer stated, it'd be a great idea if you guys would include the history of the idiom or something more educational like that....instead of repetition of the written part.

Other than that, I love it!! Oh!! And I guess to be totally inclusive in my review, I'd really appreciate it if perhaps you either would have days where you chose the Word of The Day as a much more less known word, OR have another word in addition to the regular Word of The Day, that is a "higher point" word....i.e. a word that most people do not know the meaning of, and/or a word that replaces the need to use multiple words to get the same point across.

Cough up 4 bucks for this app, people!!!


The app I think is so SO sooooo worth 4 bones. I LOVE it and the developers deserve to have this noticed and when u use a free version of an app often and you find it useful and interesting ans enlightening and well designed, it seems to me that paying for the one that costs just a few bucks is only fair to the developers. My philosophy is that when I have established I very much like the free version of any app and use it regularly, that it is a given to pitch in to support the people that made it. But... I dunno if people in this society of ours think much about the actual people behind the app... they dont get past the thought "is it free?". Well, people out there should use free apps all they want as I do, but the ones i use regularly I will upgrade once they become a common go to for me. But that's me.

This is one of the BEST yet it is more than just a DICTIONARY❕THESAURUS❕👍🏾 I am also enjoying playing the Word Games on my iPad.
🙏🏾 This APP have save me $MONEY$ 🎶🎶🎶 I have been using this APP for a while on my Galaxy S2 phone when I was out shopping to identify ingredients in products like lotions & creams so I can avoid INGREDIENTS that give me rashes.
🙏🏾 Use this APP to define words in the Holy Bible! If You want to know who will not go to HEAVEN, look up the definition of the list that is in 1 CORINTHIANS 9:10-11 & also REVELATION 21:8. To go to Heaven You must BELIEVE in your Heart in the Lord JESUS CHRIST the ONE & ONLY SON of the TRUE & LIVING GOD that he has died on the Cross for your SINS as written in the HOLY BIBLE. This App is also good for Bible Study. Sometimes those other versions doesn't translate the KJV correctly. Let God Keep You in Jesus Christ!
