Customer Reviews

She's hot, but the conversations are brief

This is definitely the best overall dictionary app that I have come across. It has the bells and the whistles, and I enjoy the blogging. I love that you can click on just about any word and it will take you to the definition. But it does have its issues. The WOD's are interesting, but they are short and lack the etymological information provided by a Merriam Webster. And the example sentences can be a bit myopic in approach. I don't need twenty examples of the same sentence. The thesaurus is awesome for the most part. But some words that could have synonyms don't for some reason. The upgrade nonsense is a bit ridiculous. I purchased the encyclopedia, the example sentences, and the thesaurus, but it still gives me ads and is trying to get me to do the "new" upgrade. Not crazy about that.

Much love

The app is amazing, and it's worth it to purchase upgrades to broaden your knowledge on whatever it is may you search for. I believe the pop ups should be removed for the people who want to just explore the app free of charge, and that it's not fair to charge people to remove the pop ups. They get in the way of people who want to quickly search without the occasional accidental tap on a pop up. Just because the prices are cheap, doesn't mean that someone wants to spend their money.

Annoying upgrade pop-ups

What an annoying experience! I look up a word not all that often (maybe once a week), yet every time it seems there is an annoyance (pop-up to upgrade, etc.) that interrupts the what-should-be simple process of looking up a word definition.

Oh... and I have 14 "messages" and 186 "mPoints" in a dictionary app!? They've destroyed the simple concept of what a dictionary app should be. I actually have to scroll down the menu to access my "favorite" words. Dictionary & Thesaurus
