I had been using Home Design Gold but found it buggy and at times difficult to use. This app is way simpler and far more stable to use. What often took 30 minutes to achieve a simple design now took less than 10 minutes. I wish I had found this app first.



This is the best app I have used on my projects, trust me I’ve used a few. So simple I recommend it.

Best 3d design app ive tried
