### 3/5 — It’s good, not great

*2020-09-08*

Their was quite a view dinosaur species missing. Some for example the most popular thanks to Jurassic Park the Tyrannosaurus Rex, Triceratops & The Velociraptor. Plus their isn’t a lot of detail on some of dinosaurs to get a general idea of what they looked or size comparisons which is one of my favorite things about learning about animals from whales, lions, dinosaurs etc. but I give it 3 stars for having a large selection of dinosaurs but if your going to call yourself a dinosaur Encyclopedia and charge for it at least give us all known dinosaurs please. Thank you!

### 1/5 — A Wikipedia front end

*2020-04-06, version 1.0.2*

This app is taking the content from Wikipedia to present as its own. It does curate the dinosaur articles in Wikipedia into something easier to navigate, especially for kids, but the impression the app description gives that they created the content is deceptive. You’ll find the same info on Wikipedia for free. Pray for this if you like the convenience but know that you are buying.

### 1/5 — Beyond Stupid

*2020-01-11*

The idea that this brain dead “developer” wants to charge you $2.99 to have access to Wikipedia copy and past information is the funniest thing I’ve ever seen. You’ll have better luck googling it yourself. This is a pathetic attempt at monetization of what basically amounts to plagiarism..

### 4/5 — Good game but needs improvement

*2019-09-11*

I wish you could get all Dino’s for free... Still good game

### 1/5 — Fine if you want to pay for Wikipedia

*2018-08-15*

The “articles” in the app are republished from Wikipedia, so I guess it's okay if you want to pay for access to a collected volume of dinosaur Wikipedia articles offline? I compared the app “article” for my favorite dinosaur to the live Wikipedia site and it was an exact match. But the links don’t work, even though they’re presented as underlined text, so it really is static, cribbed straight from Wikipedia including text formatting.

### 1/5 — Please sort the picture cropping

*2018-06-20, version 1.0.2*

Excellent content but on the iPad the heads and tails for most of the dinosaurs are off screen. If this is sorted it would score better

### 3/5 — Needs Clear Instructions

*2018-02-01*

The app has good information, but it needs clear instructions to access specific information.

### 1/5 — Missing a few dinos..

*2017-06-04*

Wrote to the company about missing Dino's from their app... said they were working for an update... that was many months ago and still no update
