Es una pena porque la idea es estupenda ### 1/5 — No funciona bien. *2022-01-05, version 1.5* El libro tiene pocas páginas que se pueden escanear y algunas no funcionan. Se ofrece com un gran complemento del libro, pero debería mejorarse para valorarse como tal. ### 1/5 — L’app non va 😡 *2021-11-02, version 1.5* Quando inquadro su scansiona questa pagina non parte😡 Buona serata ### 1/5 — Muy muy mejorable *2021-10-12, version 1.5* De los 10 o 12 codigos para leer que hay en el libro, solo funcionan 3… ### 1/5 — Should be simple…. *2021-09-12, version 1.5* Doesn’t work 🤷🏻‍♂️ ### 1/5 — App non funziona *2021-04-07, version 1.01* Dopo aver dato l’ok a tutto , non si apre l’applicazione .

Doesn’t work at all. ### 1/5 — Doesn't work *2025-01-23, version 1.5* Brand new phone and with a simple app, point and shoot, the app does nothing. There is no technical help so it's a complete and utter waste of time. A very disappointed son who does not understand why I can't make it work! ### 1/5 — App Broken *2025-01-23, version 1.5* The app requires the camera, but doesn’t request camera permissions from the device. This renders the app entirely useless and a tragic waste of 300+ megabytes of storage. Please fix this. ### 1/5 — 앱이 작동이 안됩니다 *2025-01-02, version 1.5* 앱이 작동이 안되는데 수정해주세요 ### 1/5 — 작동을 안함 *2024-12-26, version 1.5* 우쒸 애가 안된다고 울고불고ㅠㅠ 뭐 이런 거지같은 앱이 다 있노 ### 1/5 — Callate! *2024-08-15, version 1.5* Ssssssssssssss ssssssssmsssss ### 1/5 — 앱 실행이 안됩니다 책 반품 고민중 *2023-12-08, version 1.5* 아오 ## Most praised reviews (10 highest-rated) ### 5/5 — Per ora funziona perfettamente *2023-11-29, version 1.5* Libro appena arrivato ma funziona benissimo l’app su iPhone 14 pro; sia la riproduzione dei video sia l’interazione con i dinosauri ed è veramente stupendo! ### 5/5 — Gran Enciclopedia De Los Dinosaurios *2022-11-25, version 1.5* Excelente aplicación funciona de maravilla ! ### 5/5 — Genial para los niños *2022-07-21, version 1.5* Al proncipio creía que no funcionaba como he visto en otras reseñas, pero es solo cuestión de alejar la cámara hasta que encaja todo el libro y no solo el código. Hemos podido ver todos los dinosaurios y los niños se lo han pasado genial haciéndose fotos con los que aparecen en realidad aumentada. ### 5/5 — Fanastic *2021-04-04, version 1.01* The technology is a little bit fiddly, but worth some trial and error BEFORE you show the child. I’m a science graduate now retired and bought to share with a 4 year old boy. I am very impressed. Once you have the picture on the camera, move the phone to see a 3D image from any direction. Brilliant concept. Interactive. Makes the book come alive. ### 5/5 — Perfetto *2021-03-06, version 1.01* Funziona perfettamente! Molto belli i contenuti sia via che in modalità AR. ### 5/5 — Amazing app!! *2021-01-29, version 1.0* Our was given this for his birthday. We tried to download the app on a very old iPad and it didn’t work. However we then used a newer iPad and it worked a treat. It’s incredible. We were all blown away by it. Once scanned, by just holding the camera in front of the picture, you either get a video or 3D mage of a dinosaur. The 3D image is obviously on your screen but in your room on your screen. Our sons favourite birthday present! ### 4/5 — My review *2023-08-12, version 1.5* It is a cool, fun and futuristic app and book, however it is quite glitchy and especially hard to use in the car ### 4/5 — LECTOR DE CÓDIGOS *2023-05-28, version 1.5* La aplicación si que funciona, el problema es que lo que hay que escanear es la página entera en la que viene el código, no solo el código. Importante: si parece que no funciona, es porque tienes que enfocar a la página entera!!! ### 2/5 — app shuts down? *2021-06-11, version 1.2* How come the app shuts itself off whenever I open it? so upset as we were supposed to watch the 3D model of dinosaurs in the book. ### 2/5 — App keeps crashing *2021-02-12, version 1.01* App is absolutely brilliant when it works but it crashes constantly on both iPhone and ipad. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
