Very helpful to visualize your dream home plan

I purchased this app (full version) hoping this would help me on house remodeling project. Binge watching Property Brothers gave me so many ideas... I needed something to visualize plans before talking to contractors. And yes, this app has been exactly what I wanted! I love that you can duplicate a plan and make different versions easily. It has limited number of furnitures and what I see is not always a good match, but ability to change “part” of object colors separately has been unexpectedly useful. (It’s not for very detailed modification, but you can change color of cabinet counter top, handles, and the rest to different colors, for example.) Plus, you can change size of furnitures freely. You can be creative and substitute by modifying existing items if they don’t have the exact item you need. (Ex. I’ve created a “deck” by making a coffee table very big, flat & short)

One tip - if you are using an iPad like I am and frustrated that text color for notes your wrote is white font color on light gray background, change your iPad display setting from dark view to light view... I emailed customer service about it and they responded in couple days. (Thanks! :) One item on a wishlist - if we can “group” multiple objects together so that they can move around as one piece (such as table+chairs, object you created etc), that’d be awesome!

So worth it!

I love this app and I use it a lot on my iPad. I only wish that there were a few features added like the little eye dropper looking tool you use in paint or photoshop where you can replicate a color or one you’ve used previously. This would make it easier because there are many colors and patterns that are similar so it takes a minute to find the right one you used before. Another thing I wish it had is actually being able to create a second story, but on top of the first. It allows for a better visual for support and such for the upper stories. I remember in the original Sims PC games it allowed you to create multiple stories but it had algorithms in place that were somewhat following real life building codes to make sure it’s safe. You can also see where and how stairs will actually look in relation to the next floor. I know the current layout is optimal for builders but I am not one so it’s hard for me to conceptualize it when the floors are side by side. There could also be an additional button that controls what floor you see/work on, like the design and build button function. You just use it to switch between the two.

I have been using this app for months now and have loved it! I payed for the full version and even bought all the packs so I could plan things accurately. I do interior design and building plans and this helps to visualize everything easily. The only issues I had with it was some of the colors and textures were messed up with the newer packs. All the wood, fabric and wall paper textures from the newer packs had shown up in the tile section. It made it a pain to navigate through them but wasn’t a big deal.
But recently I downloaded the app onto my phone so I could have easy access to it on the go (before it was only on my iPad at home) and all my plans showed up, but there were objects missing and it said I hadn’t bought the packs. So I just figured you must only have access to everything on one device. Which is annoying but whatever. But then I went to get on it on my iPad and it said the same thing! Now I don’t spend money on apps. Ever. So this is extremely frustrating to me and I really hope someone gets back with me to figure it out! I’ve emailed with no reply.
I wish it had the option for an upstairs and roof and more plants and landscaping options. An easier way to navigate through the furniture would be nice too. Category’s inside category’s. (in the living room category have a couch category and a light category, etc. ) the search option is nice but I think this would be good too. Also triangle walls for stairs. But these things I can work around.
