This is not a full-featured home inventory management iOS application. It's primary purpose has been stated in the app description:
"The Home Inventory Easy Entry lets you go around your home with your iPhone or your iPad and take your inventory snapshots. When both your iPhone and your Mac are on the same WiFi network, you can transfer all the new photos and inventory records to the main Mac application."
This app is free and is not necessary for the main Mac Home Inventory application to work. You can acquire and transfer your inventory photos to the Mac application in many different ways.
We spent an effort to make your life a bit easier with regards to taking your inventory photos around your house and transfering them to the main Mac Home Inventory application.
