Works well

I got this app because I have always had an interest in architecture and interior design. I do enjoy this app (I got the full version, the lite was quite annoying), but it has a few areas that I would like to see improved. For one, I would like to have houses with multiple levels. Even if the floor are side by side, I would really like to have a “duplicate” feature so that I could copy the shape of the lower floor because it is quite difficult to recreate. I would also enjoy a feature that would allow me to add the wall dimensions manually rather than with the slider, because it takes a while to get the measurement I want. I do like the furniture, and the add-ons are lovely. Great choices for flooring and walls, and even the colors of the cabinets and window frames are customizable!!

The lite version, however, was the world’s most irritating thing. You could only have one room, and there were many limitations. Had no problem upgrading and I’m glad I did.

Good, but missing a few basics.

It is WAY too difficult to grab and move small items and walls, it tries to move the whole space rather than the object. In the 3D mode and moving any object, you should be able to easily toggle between vertical space and the horizontal plane. As it is, if I try to move something vertically, it flings the object out of the plan entirely when it should stay within the room, even without “snapping” on (moving something from room to room should simply take more movement, or a setting to turn on when you don’t want things to stay put), and when I’m trying to move it horizontally, it often moves vertically. I shouldn’t have to go in and out of floor plan mode just to position something correctly that should be simple.

Also, I should be able to rename a plan once it’s been created. Who’s idea was it to not allow that?

I was designing a home that I was going to build me a couple years and I found this app so I decided I’d give it a shot. I was surprised with everything that was actually in the app you can put furniture and all that other stuff in to actually see how it’s being used in the space, but I was using it on an iPad and I don’t recommend that because it’s kind of difficult to navigate through the building as your building. I definitely recommend this app for anybody that kind of wants to just play with some ideas of floorplans or kind of see how things fit together in their physical form. I like the ability to go back-and-forth from the blueprint view to the 3-D view and really get an idea how the space is being used. I got the upgraded version because the light on I want to build so much and I’m definitely Pleased with the purchase.
