Your shopping list works offline, syncs when you're back online, and keeps the whole household on the same page. ListDuo is a shared shopping list for families, couples and roommates who shop together. No account needed to start. Your lists stay on your phone, and when you sign in with Google or Apple later, everything you made comes with you. OFFLINE SHOPPING LIST THAT SYNCS No signal in the back of the store? Keep checking items off. ListDuo saves every change on your device first, so your shopping list offline behaves exactly like it does online. When the connection returns, your edits sync on their own and land on every phone that shares the list. SHARED SHOPPING LIST FOR FAMILIES AND COUPLES Send an invite link and your partner joins with one tap. Every item added or checked off shows up on their phone in real time, and a notification tells you when the list changes. Add friends once and pick which lists each of them sees. Use it as a shopping list for two or as a family shopping list app for the whole house. No duplicate purchases, no "did you get the milk?" texts. ADD ITEMS FAST Type "eggs, butter, bread" and all three land at once. Tap Quick Add for suggestions ranked by what you buy most, or dictate with the mic in your own language. WORKS WITH SIRI AND ALEXA Say "Hey Siri, add milk in ListDuo" or "Alexa, ask List Duo to add eggs" and it lands on your grocery shopping list. Choose a default list for voice and items go straight there. Sign in once to connect, then add items hands-free from any room. HOME SCREEN AND LOCK SCREEN WIDGETS See your grocery checklist without opening the app. Interactive widgets in four sizes show the list you pick and let you check items off right from the home screen. Lock Screen widgets and a Live Activity keep the open list one glance away. SORT BY AISLE Sign in and group items into color-coded categories: produce, dairy, pantry, snacks. Reorder categories to follow your store's layout, or drag items into your own order. A grocery list organizer that matches the way you walk the aisles. DETAILS THAT MATTER Attach a photo so they grab the right brand. A shopping list with photos ends the wrong-yogurt problem. Add quantity, unit, price and notes, and the list keeps a running total so you stay on budget. STAY ORGANIZED Filter by All, Buy or Bought and watch progress on every list. Archive old lists and restore them later, duplicate a weekly list, search, and filter lists by date. Dark mode, color themes, adjustable text size and 33 languages. Works on iPhone and iPad. MORE THAN GROCERIES ListDuo doubles as a checklist app for packing, chores and meal prep, or a wish list shopping app for gifts. One list per store, trip or occasion - the shopping list maker keeps them apart. LISTDUO PRO Free includes 5 lists, sharing one list with one person, 10 photos and 15 categories. Pro removes every limit, auto-shares new lists with a friend, and removes ads. Download ListDuo, the offline grocery list app that keeps working when your signal doesn't.
