How do I turn notifications on or off?

Open Profile › Settings › Push Notifications and switch Smart notifications on or off. Turning it off cancels every reminder Surplus has scheduled.

On the Plan tab, the ••• menu has two more switches:

• Meal reminders: the same switch as Smart notifications
• Cook reminders: a reminder to start cooking, 30 minutes before a meal marked Cooking needed

A meal reminder has two buttons: Log it, and Can’t eat right now, which asks again 45 minutes later.

You can also turn off everything from Surplus in the iPhone’s Settings › Notifications › Surplus.
