ShAPPes 3D shapes in AR

I downloaded this in the hopes it would allow my 7-8yr old students to build some simple castle designs using 3D shapes. The shapes move about and don’t stay into the orientation you need to combine them well. There is no lock feature. I could almost overlook that and use the tool in other ways if it wasn’t for the bizarre, breathy voice that narrates your movements. It borders on creepy and that alone was enough to make it unsuitable for use with young learners. I’d like my money back!
