### 1/5 — terrible user interface, unuseable

*2026-07-23, version 17.0*

just splatters words on the screen; no organization whatsoever

### 1/5 — No display options on Tahoe 26.5

*2026-05-24, version 16.0.2*

The search results are displayed in 8-pt font, and the Settings control merely changes the spacing of the display. I would like to see the results 12-pt font for easier reading, or maybe even bigger. But you’ve got no options with this.

### 5/5 — Dab

*2026-03-14*

A radioactive Demon core.

### 5/5 — Roget’s Thesaurus

*2026-03-02*

This is a writer’s thesaurus, sort of a reversed dictionary, and is most definitely different from your typical thesaurus. 
It’s supposed to inspire ideas, and it gives you conceptually related words to the one being searched. 
That being said, this is my 3rd(?) copy of the book; the bad reviews are those who don’t understand the purpose of the thesaurus. 
If you’re looking for a basic thesaurus, this is not it! However, I will say that this is 100% my most used tool and provides exactly what it is intended to do.

### 1/5 — Roget's II: new thesaurus

*2026-01-25*

This is a bad product. Can't say enough how lousy. You will be surely disappointed, don't waste your time. See for yourself right now:

Example: word I researched: "carnivore"

App supplied these supposed "synonyms":  amphibian, aquatic, biped, board-and-roomer, boarder, bon vivant, Brillat-Savarin, canine, cannibal, Chiroptera, connoisseur of food, consumer, cosmopolite, diner, diner-out, eater, eater-out, epicure, feeder, feline, flesh-eater, fruitarian, gastronome, glutton, gnawer, gourmand, gourmet, grain-eater, graminivore, granivore, herbivore, high liver, hungry mouth, insectivore, invertebrate, lactovegetarian, Lagomorpha, Lucullus, luncher, mammal, mammalian, man-eater, marsupial, marsupialian, meat-eater, mouth, omnivore, omophagist, pantophagist, phytophage, picnicker, plant-eater, predacean, primate, Primates, quadruped, reptile, rodent, Rodentia, ruminant, scavenger, trencherman, ungulate, varmint, vegetarian, vermin, vertebrate

### 5/5 — Roget's Thesaurus: A Must Own for Every Writer.

*2025-08-29*

Roget's Thesaurus gives a writer the essential tools needed to publish polished prose without the need to repeat the same word(s) over and over and over again. 

It's not as if the cost of Roget's will break the bank. It might even create the conditions that make publishing possible.

### 5/5 — …..

### 1/5 — User Interface needs improvement

*2025-03-10*

paid $4.99, had a lot of other options which were free... bad decisions is all I make :-)

### 4/5 — The First Go To Word Source

*2024-12-26*

I want to update my review of a year ago of app “Roget’s II The New Thesaurus-Third Edition”. My clue should have been the rebranding of it as “Moby Thesaurus II” which in reality, is The Roget’s Thesaurus Light. I just queried the word “seismic” and nothing came up after repeated tries in different contexts. I then consulted my real Roget’s Thesaurus in my paperback Penguin Reference copy, edition of 2004, and sure enough, it was in there with loads of related words. Moby II is okay as an app, but it’s not the real (and thorough) McCoy! I’ve reduced my former 5 star rating to 3 stars.

### 5/5 — Antonyms
