Connect your Fitbit (token method)
On the web app, open the menu -> Account -> Generate Tokens. Copy both Access Token and Refresh Token.
On your phone in the Fitbit app, open the WrGroceries app settings and paste the tokens into Access Token and Refresh Token. Save/close settings.
Launch the WrGroceries app on your watch. It will sync your current list automatically.
WrGroceries Fitbit setup Access Token: <paste> Refresh Token: <paste> Updated: keep the date you generated new tokens Notes: tokens are personal—do not share them.
Token login is recommended and more secure than username/password.
If tokens expire, regenerate them in Account and paste new ones into the Fitbit settings.
Using the watch app
Swipe to switch lists if you have multiple lists.
Tap an item to mark it done; the phone updates automatically.
If you want a different list, swipe to lists and pick it - the watch also updates your last-used list.
If you see activation/login errors
Open the Fitbit app on your phone, ensure Bluetooth is on, and reopen the WrGroceries watch app.
If tokens were not pasted, add them in the WrGroceries Fitbit settings. As a fallback you can enter your WrGroceries username and password in the Legacy Login section, but tokens are preferred.
After updating settings, launch the watch app again to refresh the connection.
