Won’t launch on my iMac running 10.13.6. Sent messages to developer 6 days ago. No response.

Not too bad for $3.99, but needs improvement. There is a feature with a camera button, that says it saves it to your gallery. I can't figure out where the "gallery" is. The simplest way to save a picture outide of the app is to take a screenshot.Library of furniture etc: Not nearly enough choices. It's difficult to manipulate the 3-d view to get a screenshot of the correct angle. No laundry facilities, and too few kitchen options. There is one kitchen island with barstools, but it has to be placed at a straight angle. I need to place it diagonally within the room, and it is not possible. Same thing with the bathtub. It's just too limiting. It needs some basic shapes that you can stretch to fit, which could simulate furniture. This would help make up for the lack of choices. Flooring: light brown wood only. No other choices. It would be nice to have a more open floor plan. There is a feature to remove a wall (open doorway in the library), but it leaves a white line on the 2D view. In the 3D view, I was unable to completely remove a wall. It left what looked like a structural pillar in the middle of the room. Steps: Full staircase only. No option for 2 or 3 steps. Functionality: A little sticky. It's necessary to click on some items multiple times to select. Several times I had to move an entire room to be able to select an item within a room. Over all, I guess you get what you pay for. It's easy to use, and makes a decent 3D model with many limitations. It's not possible to directly export a design without taking a screenshot. It's fun to play with. No in-app purchases.
