1. 4/5Very nice, but two things need fixing...

   While WOD is both impressive and entertaining, I did find two glitches that need some attention. First is that the information page for Troodon is in Spanish. Now, if I were fluent in Spanish this really wouldn't be much of an issue. Sadly, I'm no good at reading or speaking Spanish, so this is a bit of a bummer for me. The second thing is the image for Iguanodon doesn't display, even though its information page does. Instead of the intended image showing up, I get the far left portion of the previous dinosaur's image (regardless of which direction I approach from). Kind of odd, I must say. But even with these two issues I still think the app is very well done. Could use a few more dinosaurs, though... and pterosaurs, too... some more marine reptiles would really nice, as well, and maybe you folks could toss in some crocodyliformes just to be sure, OK? Thanks a bunch, and keep up the good work! ;-) OK, as of August 22, 2018, I just updated to the latest version and now it won’t let me do anything but change the icon. Not sure what is going on, but I even restarted my iPhone and it made no difference. Any advice on how to solve this issue would be greatly appreciated! Thanks!! August 23, 2018 update: Great job getting the bug in version 6.4 fixed!! A very fast turnaround that really earns a lot of praise for your efforts; well done!

2. 4/5It Could Almost Be Paradise

   First of all this is a fun and worthwhile companion for bite sized information on dinosaurs and other extinct reptiles. I love having a “go-to” app for referencing Dino facts and species. And I’d be thrilled to rate five stars, but I really want this app to be a little more user friendly with regard to finding and viewing key information. I can tell they’ve put a lot of attention into the visual aspect of this app (and it’s beautiful ) but I’d love to see at least the species name on each animal’s splash page, instead of having to click (i) just to learn what it is you’re looking at. Also, a more accessible ‘search’ function would be lovely right from the start. It would make all the difference between a four-star experience to a perfect app.

3. 1/5Horrible app not reference

   Worst app I have ever purchased. Not worth anything unless you are under 5 years of age. I really expected more from this app. It should not be under reference. I was looking for an app that could provide easy alphabetical access and this was not it. Preview images are misleading. Edited to respond to dev: I am accessing this app on the iPhone X. After dedicating more time than this app is worth to see if the 🔍 would appear on any part of the app, I finally managed to access it under very strict and specific circumstances. You must go to the pull up menu and click back on “dinosaurs” this will bring up the panoramic image and the 🔍 will appear- if you move your phone or touch anywhere else the 🔍 icon will disappear (doesn’t matter if you are using the accelerometer view or scroll view). It does not appear under any other circumstances or on any other page or even in the pop up menu (where it belongs). I have sent screen shots of this issue directly to the devs and I hope they will fix this. Until this is fixed the app is not worth it and my one star review will stand. The 🔍 icon should not be an Easter egg that the user has to find. I paid for this app and I want to be able to use it as an educational resource. I want it to work. I would be more than happy to amend the rating and review if and when it becomes what it claims to be.

4. 4/5This is so cool!

   I am autistic and my special interest has been dinosaurs for a while so I was really excited when I found this app. It seems super cool so far! I’ve been playing around with it on both my phone and my Apple Watch. I was specifically intrigued because of the ability to have some more dinosaurs on my Apple Watch. I’m thoroughly enjoying the app so far. It’s really quite comprehensive. I’m a bit saddened by the fact that you have to pay for the app and also subscribe and pay for the Dino directory though. However, latest scientific updates/news, glossary, anatomy, and everything is super cool and I love that I can just access it all through an app. The info on the Apple Watch is limited and I would love to see that expanded on more soon!

5. 4/5Is 4.9 an option??

   This app is great. Bought it for my 2 year old son who has this awesome fascination with dinosaurs. Bought it only for the AR portion but the rest of the app seems fantastic and as my son grows, he will continue to enjoy the rest of what this app has to offer. Giving the app a 4 out of 5 because when using the AR everything but the dinosaur seems blurry. So taking a photo of my son next to a T-Rex is great but wish he was clear in the image. Truthfully maybe I am doing something wrong when taking the photo on my iPhone X, but I’m not sure. Giving a 4 out of five because 4.9 out of 5 is not an option.
