The Your Grocery List app is available in the Gear app store! Install it from the Gear app on your phone, enter your email address and PW to sign into your Our Groceries account on the watch, and start shopping! Thank you, Christoff!
Requires an account w/Our Groceries. Does not require the Our Groceries app on your phone, but that is highly recommended (it's simply a great shopping list app - once you/your family start using it you'll wonder how you got by without it).
You can create your Our Groceries account from the Our Groceries app on the phone, or at www.ourgroceries.com.
This is a community developed app, Christoff (developer) contacted Our Groceries and they were supportive of him releasing it.
Currently the app does not have "push" auto-sync w/the Our Groceries server, so use the Refresh button in the app to update before shopping (in case changes have been made to the shopping list from another client). All changes on the watch to your shopping lists are immediately sync'd w/the Our Groceries server. Christoff is investigating auto-sync from the server to the watch.
Any enterprising developers who also have to go shopping for groceries (100% of you!) - you could look into the Our Groceries app!
It's probably the best shopping list app available on Android (nearly instant sync across multiple devices, extremely flexible list management, super easy to use UI, regular maintenance and updates from developer, etc.
Would be great to have a Tizen client to view current list of items and check off as purchased from the watch.
Willing to provide beer money to help get this started.
UPDATE: Member cm_walkaround has started working on a native app solution for Our Groceries sync. See this post (#6).
UPDATE 2 WOOT! Christoff just announced that he released the app to the Gear store today (Feb 21) in this post (#9). It will take several days to a week for Samsung to review and approve it. They control the final actual release of the app in the Gear watch store, so hopefully they will complete their review promptly.
The app is called Your Grocery List. (Christof did not call it "Our Groceries" to avoid confusion about the source of the app).
Thanks (mine and all other Our Grocery users) for looking into this!
