### 5/5 — Excellent tool!

*2024-03-23*

Thank you very much!

### 3/5 — Incomplete

*2024-02-04*

I generally like the app’s functionality with some niggles. However the biggest issue is the absence of some relatively common words eg acuity.
 Also the linking seems faulty eg if a search for ‘recant’ gives a list including ‘disavow’ then shouldn’t it also be vice versa? Real shame.

### 5/5 — Favourite

*2024-01-15, version 5.6*

Buy to support a developer who doesn’t collect any data and offers their product for free as well. Nice QOL additions for the price.

### 4/5 — Small annoyances

*2022-11-13*

I have been using this Thesaurus App for many years with mixed success, more and more recently a word that I enter is not recognised. I check the spelling so I know that is not the issue. I enter the same word into its sister dictionary and it comes up . It is not as though the words are obscure, the latest was crustacean, not an obscure one I would have thought. I don’t know what the developers can do other than increase the stored words. But I suspect that is easier said than done. I will just keep my fingers crossed. Apart from that an excellent App.

### 2/5 — The faulty interface irks

*2020-11-03*

The search field is not immediately available unless triggered. It opens to a random entry and searching requires a few unnecessary clicks.

### 5/5 — Surprised and disappointed....

*2020-02-19, version 3.85*

...that this excellent application no longer works on my iPad running OS12.4.5, needing instead OS13. Since it worked perfectly well before, I can't really see any reason for the new OS requirement. I hope that it’s companion, the Chambers Dictionary, will not likewise become inoperative.

### 1/5 — ダウンロードできない

*2019-12-08*

使えません。お金を返して。

### 1/5 — Broken

*2019-09-27, version 3.80*

After the latest update it now crashes when opening. It was a great app, but the update has rendered it useless.

### 1/5 — Latest iPad OS update broke app

*2019-09-26, version 3.80*

This app now refuses to open and immediately crashes with the latest iPad OS update. I’ve tried to get help via the developer website but there is no troubleshooting or help section at all. 
App now useless. Such a pity because it used to be great.

### 1/5 — Not convincing

*2019-09-04*

It’s been about 4 years I’ve been using this app however the thesaurus is not that much persuasive. I expected something more.
