ListNudge

Features
Read full description

ListNudge is the grocery list that remembers for you — and knows when you're standing in front of the store. Add milk to the list from your couch. Your partner sees it appear on their phone before they've left work. Whoever gets to the store first checks it off, and everyone else finds out instantly. No group chat, no "did you get eggs?" text, no forgotten items — just one list, shared with the people who shop with you. STORE NUDGES, NOT JUST REMINDERS ListNudge watches the stores you actually shop at and quietly nudges you the moment you're nearby — only if your list actually has something on it. Walk past a grocery store with an empty list and you'll never hear from it. Set quiet hours so a 2am errand doesn't buzz your phone, and choose whether nudges fire for any store or just your favorites. BUILT FOR THE WHOLE HOUSEHOLD Share any list with the people you shop with, and see who added what and who checked it off — right down to "Kai got it." Items sort themselves into Produce, Dairy, Bakery, Pantry, Frozen, and Household automatically, so a fast-typed list still turns into an organized one. MULTIPLE LISTS, YOUR WAY Keep separate lists for the weekly shop, a Costco run, or the kids' snack drawer — each with its own icon and color. Everyone shopping that list stays in sync, no matter which one they're looking at. NOW SUPPORTS IPHONE DUO ListNudge now supports iPhone Duo. With the Duo open or partly open, your lists and the open list sit side by side, so you can see everything you're shopping for at a glance. Closed, you get the familiar single-column layout. HANDS-FREE WITH SIRI "Hey Siri, add an item to Weekly Groceries with ListNudge." That's it. Items land on the right list without opening the app. PRIVATE BY DESIGN ListNudge uses your iCloud account for sync and sharing — there's no separate login, no account to create, and no third-party server ever sees your list. Everything moves directly between your household's devices through iCloud. Whether it's one person keeping a running list or a whole family coordinating groceries, ListNudge makes sure the list is always current, always shared, and always right there when you walk in the door.
