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.

Potential but no one at home?

This was exactly what I was looking for so tried the lite version and liked it very much. I tried to buy the full version through an in-app purchase and thought it had gone through but my icon and apple store still say I still have the lite version. So far, so good. Two days later the app now crashes every time I add a window or door to a wall. The program sends an email to the developers when it crashes BUT the address does not exist and so it is returned undelivered. Where did the developers go? There doesn’t appear to be any support for the app. I am left wondering whether I should buy it again and start over but fear I will just loose another $6 plus all the floor plans I already have created. Writing a review appears to be the only way to contact the developers. I hope they will fix this bug (it had worked fine until today) and will make certain I have the full version. I really like the app when it is working!

For once an app with no glitches when I do stuff! Also there are no coins, like you have to pay $100 to get a Couch. Every ting is free! Even though you can only design one room in the lite version it is worth it. Just make a big room with different sections. I am very pleased. I got the game on a Wednesday and by Friday I completed my dream home.😍 truly I get why you have to make a lite version and I don’t blame the designers for making a one room restriction on the lite version. Does it bother me? Yes. Do I like it? No. But do I get why they have to make it so? Yes. People have to make money. You need to have money to live. I highly suggest this game and I thank the designers for making such a good game where you can design simply and quickly. I hope after reading this you will get this app. It is TOTALLY worth it!
