Splash Shopper Shopping Desktop is better than what I'm willing to spend the time to create but not as good as I'd like.
On the plus side: it synchronizes to and from my IOS devices. It is generally easy to use and not confusing. Handles multiple prices at multiple stores.
Printing is lousy - no control of size or fonts. Not necessary if you are carrying your IOS/Android device, but I like a printed list for backup.
Synchronization sometimes shuts off my iPad wireless - causing confusion until I notice it.
Should be harder to Mark/Unmark an item as completed. Just a longer click hold would do it.
