Cool new look

I noticed Object Viewer has a new look, which is very nice. I’ve been using this app for about 4 months now and I love it. It takes a bit more creativity to use this app than Explorer, but there’s a lot of versatility. It’s enjoyable to go through the collections and see the various objects and I find the app very simple to use. My niece enjoys it, and I sometimes show her objects on the cube while teaching her about things like planets and dinosaurs. She is pre-school but I think it is important to get kids comfortable and familiar with technology that may be a big part of their lives in the future.



I stumbled across this app after seeing an ad and I am soooo glad I did. I cannot wait to use this with my students and my own kids. I am a K to 8 STEM teacher and this is a Seriously amazing teaching tool! I love that you have the option to use the cube, 3D, or real word view. I can see so many possibilities for enhancing current lessons with this app!I haven’t explored it yet, but looking forward to trying out the printable cube with my students!! Would recommend to my colleagues for sure!

How useful, as well as fun!

This is the first time I have been inspired to write an app review. I work in a college where we do a lot of 3D modeling. I always wondered if the Merge Cube could somehow be used to view students STL files. This app is amazing! Been fascinated viewing my own designs held and rotating in my hand. It works beautifully in real time. Only request I have is to be able to adjust lighting, it gets a bit difficult to see details at some angles due to brightness. Thank you....Amazing!
