I was able to see the Actions menu once or twice. I saw the Skeleton and Drive menu there . I can no longer bring up those menu items, no matter how often I tap the menu. Asking the developer 2 questions: 1. How to see the menu again? 2. Are there any tips to get consistent results? It seems very particular about angle and lighting. Thank you. ### 4/5 — Good *2026-02-12, version 3.16* Add more dinosaurs! Other than that it’s good. ### 2/5 — Good but one issue *2026-01-14, version 3.16* So I had this app a couple years ago on an old device but it says to deauthorize it but I don’t have it anymore so maybe can you make it so the same serial number can work on multiple devices ### 3/5 — Can’t re-install app *2023-03-30, version 3.16* My old phone died in water and I can’t reinstall the Dinosaur 4D+ app on my new phone as the app says I have to deregister the old phone first. Can the developer tell me the solution or provide an email address? ### 4/5 — Cute! App is a bit frustrating though *2020-08-15, version 3.6.8* I love the idea of this and my son has a blast looking at the dinosaurs! However, I find that about half the time when I start the app up it freezes on the loading page, and i have to force shut down the app and restart. Generally by this time my toddler is pretty impatient haha. ### 4/5 — Great app, BUT... *2020-05-22, version 3.6.4* This is a great app, but I just wanted to say something can u make it so that I can see the dinosaur even if it gets of card? Because when I try to do that it just blinks out of existence. Also please add some more Dino’s other than that it great thanks:) Ps pls remove the serial no. Thing ### 4/5 — Where’s my boi Stegosaurus *2020-03-15, version 3.5.7* Where is the Stegosaurus ### 3/5 — VR MODE *2020-01-01, version 3.5.7* been having trouble finding the VR MODE selection... missing out on that since my daughter would mainly use her headset on that ### 3/5 — Not very clear *2019-12-28, version 3.5.7* This seems to be a very good idea but I’m not getting all the features on the app, I’m not getting drive mode only action and facts. The instruction are a bit basic as I’m trying to set up vr mode using the utopia headset but the Manuel says select vr mode I’m not getting any of these settings, any help from the developer would be amazing. ### 2/5 — VR mode not show *2019-12-25, version 3.5.7* I am trying to find the VR mode so my son can use the goggles and I have pressed every single button the features option doesn’t show the VR mode like the manual states. Would be given more stars if I would have JUST purchased it for the phone. But it was the goggles that made it interesting. ### 2/5 — No need for the headset *2019-09-26, version 3.5.7* So everything was easy to set up and works okay but the app does not hage the different modes like the instructions say so we don't use the headset for my son which is sad because he loves the headset and he is 4 years old. Also the dinosaur keeps disappearing and sometimes it doesn't read the cards. I don't recommend and I'm going to return it. I have the Iphone XS Max ### 2/5 — Stuck on “Collecting Data 30%” *2019-09-02, version 3.4.13* First time I tried this app, it worked ok. Now it does not go beyond “Collecting data 30%” on two independent iOS devices. Currently useless... ## Most critical reviews (10 lowest-rated) ### 1/5 — You actually have to email them to deauthorize old devices *2022-03-10, version 3.12(4)* What a terrible design. Kids just want to play this stupid game and it was setup on multiple old phones, you get locked out and you have to email them to deauthorize your old devices. They never return an email or do as you ask. Waste of money and waste of time! ### 1/5 — Serial number invalid *2022-01-05, version 3.12(4)* Got it for Christmas. The included serial number gives an error that it is already registered to another device. I submitted a support request and am now wondering if the company still exists. No response so far. ### 1/5 — Serial Number Problem *2022-01-02, version 3.12(4)* “Sorry, the serial Number you’ve entered has been registered in another devices, please deauthorize one of your devices to proceed”. How is this possible? It was a Christmas gift for my nephew. I opened the box. It was a New one and dosn’t Work. It’s awful!!!! Please, resolve this as soon as possible. Thanks! ### 1/5 — WHAT THE HECK!?!? *2020-03-20, version 3.5.7* I really do not like this app. In the instructions they say the VR and AR mode are in the bottom left corner... IT IS NOT!!!!!! I got so fed up that I packed it all up and started to read the reviews. There was one that had the same problem as me. There was a developer response and it said the the VR and AR mode can only be used on devices “6 inches or under”. My phone is the iPhone XR. It’s 6.1 inches. IS THAT NOT CLOSE ENOUGH TO 6 INCHES?! DO NOT GET THIS APP!!!!! ### 1/5 — Nur AR - kein VR *2019-12-31* Wozu ist die Google Cardboard Hardware gut, wenn VR gar nicht unterstützt wird? Leider totaler Mist - das Bild von dem Google Cardboard ist unscharf (Google Cardboard Demo App) und wie gesagt, die eigentliche Dinosaur 4d+ unterstützt kein VR Modus (iPhone Xs Max, iOS 13.1.3 ### 1/5 — Can’t input serial number *2019-12-25, version 3.5.7* I have read the reviews and the standard response from the developer and followed the trouble shooting instructions... however it is still not working. I have the card with the serial # on it but there is no where within the app to enter it. It says the app will automatically scan the card but it does not.. any help (besides your standard template response) would be greatly appreciated. ### 1/5 — Stuck *2019-11-26, version 3.5.7* Bought the flash cards and the app but when I fix the camera on the card it just pops up with a box for a serial number even though everything is up to date. Could use some advice? :) ### 1/5 — Solo está en inglés *2019-10-05* Debería haber una opción para cambiar el idioma de la aplicación 😒 ### 1/5 — App won’t load *2019-08-31, version 3.4.13* App gets to 66% loaded and won’t go any further ### 1/5 — App fails to load *2019-08-31, version 3.4.13* App hangs during initial data download 😭. Perpetually stuck at 66%. Upon restart it attempts to “collect data” but hangs at30%. Will be returning the Dino cards. ## Most praised reviews (10 highest-rated) ### 5/5 — Very impressed *2026-06-29, version 3.16* Bought these cards for my 6 year old, simply beautiful.!! ### 5/5 — Best app ever *2026-04-27, version 3.16* I got my cards and I know the serial number. ### 5/5 — Best Dinosaur Toy Ever – Still Unmatched After 7 Years! *2025-06-12, version 3.16* This is hands down the coolest and most educational dinosaur toy I’ve ever seen! It teaches you the names of the dinosaurs based on how they sound, shows how they move, displays their skeletons, and even gives detailed information about each one. You can interact with them through your phone or iPad camera as they come to life in front of you – it’s like real-life VR without needing goggles! I bought this game for just $10 at Barnes & Noble back in 2018, and now it’s 2025 and STILL nothing compares to it. I was surprised to see it had bad reviews, but I realized it’s probably because people lost the key card – which is essential. Just a tip: don’t bother with VR glasses, just use your phone or tablet! Huge thanks to the creators of this game and app – you deserve an award. Honestly, it should be priced at least $100 for how amazing and educational it is. ### 5/5 — Great Fun for Kids and They're Learning at the Same Time *2023-03-21, version 3.16* Lots of fun. A great product. Highly recommend. Put two or more dinosaur cards in view of the camera and let them go. ### 5/5 — Amazing!!! *2022-03-05, version 3.12(4)* Brilliant app. Kids have spent hours with the dinosaurs. Makes for an interesting car ride on long journeys. ### 5/5 — Amazing! *2020-04-10, version 3.6.4* Amazing idea and amazing quality and amazingLY good fun! ### 5/5 — Can you help *2019-10-14, version 3.5.7* Hi I love your app it’s the best. Can you help I can’t do the crazy I don’t have the serial number can you send me it thank you ### 5/5 — Best app ever *2019-08-12, version 3.4.13* This is the best app. I’m playing on my iPad it’s so much fun! ### 5/5 — Serial Number *2019-06-07, version 3.4.6* How do we find the serial number? ### 5/5 — Awesome toy *2019-03-02, version 3.3.1* If people would actually READ the instructions they would be able to enjoy the product --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
