### 5/5 — I cant believe i'm the first to leave feedback

*2024-02-11*

Excellent app, for a few quid, it's well worth it!

### 5/5 — 連携

*2017-11-03*

他の辞書と連携が出来て便利です。

### 5/5 — Does the job

*2017-10-27*

Really easy to use and lots of words

### 5/5 — Super!

*2012-11-24*

Sehr umfangreich, lohnt sich!!!!!

### 5/5 — Free Dictionary

*2012-04-24*

Not only defines a word but gives option for synonym & acronym

### 4/5 — Essential for all writers

*2011-07-30*

This is the best thing out there if you're looking for an app that will give synonyms for all possible meanings of a word, whether the word is colloquially used or traditionally used. Will also list multiple-word terms. Thesauruses (thesauri?) only list strictly related synonyms to a word's traditional use and possibly some colloquial and the number of similar words is always pretty limited. Not so for companion synonyms. It's true that the bookmarking system is a bit clunky (bookmark something and then navigate to the same word via another means, and the bookmark+notes don't come up) and there are some simple things that could be added to improve user functionality but I find the value of the app far outweighs any minor issues. I hope they continue developing the app and adding to its lexicon because it really is a must-have for creative writers.

### 1/5 — 使えにくい

*2011-05-29*

コンテンツすごいですが、なかなか使えないです。
例文 解釈も全くない。

### 3/5 — Confounding, beclouding, obscure...

*2010-08-20*

The entries do contain lots of good synonyms but you have to sift through many words that are in no way associated with the query. If English is your second language, beware.

### 1/5 — 検索結果について

*2010-01-01*

良く見ずに購入してしまいましたが、類義単語の順番がabc順になっています。
abc順ではなく、意味が近い順や、複数の意味がある場合意味のグループごとに掲載されていればより分かりやすいと思います。

### 1/5 — Not Helpful!!

*2009-10-21*

I was skeptical about downloading from a site without User Reviews, but decided to purchase the App anyway... Big mistake! I had to write several papers and could not even find one appropriate synonym! The "Check Synonym" feature with Microsoft Word is a better Resource.
