In the middle of the lesson the app will close out. ### 2/5 — Mal funcionamiento en IPad *2023-11-06, version 3.4.11* La aplicación se demora demasiado en funcionar en IPad. Los elementos cargados no funcionan o generan cierre en la app. Esto sucede a pesar de haber visto el funcionamiento de los mismos modelos en la app previamente. ### 2/5 — Sin soporte para landscape *2023-09-05, version 3.4.9* Muy buena app, pero sin el soporte landscape para proyectar por AirPlay no sirve ### 1/5 — No carga *2023-09-04, version 3.4.9* No he podido utilizar nada. Cuando esté listo será fenomenal. Mientras, es perder el tiempo. ### 5/5 — Faszinierende AR-Erfahrungen mit Merge Cube's Object Viewer App *2023-06-09, version 3.4.5* Merge Cube's Object Viewer App bietet eine beeindruckende Augmented Reality-Erfahrung. Die Benutzerfreundlichkeit, die Vielfalt der 3D-Objekte und die Interaktivität der App machen sie zu einem großartigen Werkzeug für unterhaltsames Lernen und Entdecken. Die Stabilität und Performance der App sind ebenfalls bemerkenswert. Empfehlenswert für AR-Enthusiasten! ### 1/5 — Inutilisable en classe *2023-05-16, version 3.4.5* Application autrefois gratuite, mais devenue accessible uniquement avec un compte individuel, premium, et payant bien entendu. Les quelques modèles gratuits sont trop maigres pour offrir un quelconque intérêt. Application supprimée. ### 5/5 — Engaging AR STEM Tool *2023-05-11, version 3.4.5* This app is used with the MERGE Cube. It has several free options. My school subscribes to the paid version allowing simultaneous use of 30 students at a time. Teachers and students love it. Very engaging and lots of lesson ideas for C&I integration. Students are able to upload their own 3D creations and label and add details. This is a great interactive STEM tool. ### 1/5 — Terrible *2023-05-04, version 3.4.5* It sucks ## Most critical reviews (10 lowest-rated) ### 1/5 — Will not let me refund *2026-03-01, version 3.5.7* I got a free trial but it won’t let me cancel it and it charged me again horrible app does not even show you where to cancel subscription ### 1/5 — No carga visualizaciones *2025-09-21, version 3.5.4* Selecciono lo que quiero visualizar con ayuda del cubo y nunca carga, al parecer ya quedo obsoleta la aplicación o la descontinuaron. ### 1/5 — Juifs *2025-09-10, version 3.5.4* Mon prof de svt m’a piraté mon compte help je hais les feujs ### 1/5 — App funktioniert zur Zeit nicht *2024-11-06, version 3.4.31* Kommt leider nicht über Status „Verbindung mit Dashboard…“ hinaus. ### 1/5 — iPad se cierra continuamente *2024-05-15, version 3.4.23* Cuesta que cargue y se cierra continuamente ### 1/5 — Horrible App *2024-05-01, version 3.4.20* Keeps crashing and won’t load any objects 😞 🤫🧏‍♂️ 🤚🙂‍↕️ ### 1/5 — Im regretting it *2024-01-17, version 3.4.13* The app crashes almost Constanzen I try viewing my own objects. Also, when I try to add labels to my objects the just float around and sometimes even collide with the shape itself, making it unreadable. It doesn’t help that you can’t move the labels to where you want when you place them. And don’t get me started on the online 3D interface. Any and all changes are simply NOT APPLIED. Imagine painstakingly fine tuning your model, clicking save, exiting the viewer, just to find out your changes weren’t implemented ### 1/5 — No abre sesión jamás *2023-11-27, version 3.4.11* No abre sesión y no he podido utilizar la app, siempre marca error. ### 1/5 — Va fatal *2023-11-23, version 3.4.11* No te deja registrarte, he intentado hacerlos desde varios correos y no te deja.

Using the Merge Cube, students can hold, examine, and interact with detailed 3D objects right in their hands, creating a level of engagement that is hard to match. What I appreciate most is how easily students can explore objects from every angle. Whether studying science, history, geography, or STEM concepts, the ability to manipulate and investigate 3D models helps deepen understanding and sparks curiosity. Students are naturally drawn into the learning experience and often spend extra time exploring and asking questions. As an educator, I also appreciate how simple the app is to use. The interface is intuitive, the models are impressive, and the overall experience is both educational and engaging. Merge Object Viewer has become a valuable tool in our classroom, helping transform abstract concepts into tangible learning experiences. If you're looking for a way to make learning more interactive, immersive, and memorable, Merge Object Viewer is an excellent choice. ### 5/5 — Almost Perfect *2025-09-08, version 3.5.3* The merge cube lets you display 3-D objects on a simple cheap foam cube. This means that you can hold and move 3-D models by looking at them through this app. The upload support is top-notch. Exporting from Feather 3-D (AMAZING for figuring out concepts with simple modeling) on iPad, importing models is one click. The ability to build structures and interact with uploaded objects in the real world , scaling them up to room size, is remarkable. The tracking is excellent, and brings a level of immersion I did not expect. Wish list: Allow objects in World mode to snap together (horizontally + vertically), a camera button, and bring back VR support! ### 5/5 — Amazing Learning Tool! *2025-01-07, version 3.4.32* Object viewer is truly unique. Teachers can have any teaching aid right at their fingertips to enhance a lesson. Students can explore their interests and search through a wide variety of collections. This makes science so fun and engaging! ### 5/5 — Wow factor granted *2024-08-15, version 3.4.26* Amazing app that combines content and competences for kids and adults! Fun and learning made interactive. ### 5/5 — Worth every penny! *2024-06-03* This app is incredibly engaging and easy to use, offering remarkable versatility. It makes learning fun for children. Teaching and learning with this app and the Merge Cube is highly effective using true-to-life aids you can hold and interact with. You can even upload your own 3D objects. ### 5/5 — Amazing! *2024-03-22, version 3.4.19* This app definitely gets 5 stars in my book! It works amazingly well and the objects viewable are truly educational and engaging for students! This app definitely brings science to life and allows students to become personally connected to their learning! ### 5/5 — Science, STEM, Storytelling! *2024-02-06, version 3.4.16* I am in love with this app! There are countless manipulatives available in the library! As with Merge Explorer, you can place these into your current environment, but this particular app allows you to add and move several different objects into an environment! It saves your work, and you move the next object in. This will allow students to do storytelling with the objects!! I see great cross curricular opportunities here- science, STEM, ELA, Social Studies, and theatre could all “merge” together here to create profound learning opportunities! ### 5/5 — excelente ! *2023-12-22, version 3.4.13* .. las animaciones, el poder "copiar objetos" y la idea del cubo son fantásticas ### 5/5 — Having fun and learning at the same time! *2023-06-27, version 3.4.6* I love using Merge cubes in my classroom. Students hold the foam Merge cube in front of a device and can see 3D objects and learning concepts. The ‘wow factor’ factor never gets old when students first use the Merge cubes. I love it when learning can be fun! ### 5/5 — Excellent App *2023-06-20, version 3.4.6* Merge Object Viewer is an exceptional 3D object exploration app. Its intuitive interface enables effortless navigation and interaction with models. The app's ability to merge objects seamlessly allows for limitless creativity and experimentation. With superb rendering quality, extensive file format support, and convenient sharing options, Merge Object Viewer is a must-have tool for educators. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
