Cost: Free for iOS
What It Does: Lets users create color-coded shopping lists, add items, and cross off items. It also keeps a history of items the user has added in the past for quick addition of regular items.
What I Like: ShopShop is one of the handiest third-party apps Brian and I use. It lets us use Dropbox to sync our shared shopping lists between our iPhones. Side benefit: When we have gotten separated at a store, I have refreshed my list to see what things he has crossed off so that I could estimate his location.
What I Dislike: In the rare event when we both edit the same shopping list at the same time, Dropbox gets confused and creates a conflicting changes file with one person’s edit. It still shows up in the ShopShop app, so we just have had to combine the lists and then delete the conflicting list.
Disclaimer: I don’t own or have any vested interest in this or any other apps nor am I responsible for how you or anyone else choose to use them. Do your own research and make wise decisions!
Bonus Tutorial: How to set up syncing & sharing
1. Person A (me) syncs her ShopShop account with her Dropbox account. Tap the “Three bar” button in upper left corner > Choose Settings > Turn Dropbox Sync on > give permission for ShopShop to access Dropbox.
2. Person A goes to Dropbox on her computer and shares the whole ShopShop folder with Person B (Brian).
3. Person B syncs his ShopShop account with his Dropbox account. (See step 1 for directions.)
Now both people can add and cross off items from the lists.
I also have a third device, my iPod Touch, that syncs the same lists through my Dropbox account. The iPod stays in our kitchen or adjoining laundry room for various uses, including conveniently updating our shopping lists when phones are not handy.
