For roommates
Household groceries shouldn’t live in three group chats. Invite your roommate once, then keep a split grocery shopping list that updates live — who added paper towels, what’s already in the cart, what’s still needed.

Stop buying a third bottle of oat milk. A shared cart app for roommates shows what’s already listed before anyone hits the store.
Everyone adds what they need. The live list makes it obvious who contributed, without a spreadsheet of household expenses.
Mix of phones is fine. This shared cart app for iOS and Android keeps the same collaborative cart on every device.
Household basics should not live in three chats. These reads cover live lists, mixed phones, and fairer shops.
Roommates and small households need more than a shared doc. One collaborative grocery list stays current while people add from different rooms.
Mixed-phone households can’t share Apple Notes. A shared grocery list app has to work on iPhone and Android together.
The person in the aisle should see new items before checkout. That is cart share — not a screenshot of yesterday’s note.
Keep is a notes app. It does not bag, skip, or stay usable while one of you is already walking the store.
Roommate kitchens produce the same failure mode every week: three people buy paper towels, nobody buys dish soap, and the group chat is a graveyard of “did we already get oat milk?” A split grocery shopping list only works if it stays current while people add from different rooms — and different phones.
CartTogether is the app to share a shopping cart with your roommate without forcing everyone onto the same notes app. Invite once with a link or join code. From then on, the household cart syncs in real time: adds, quantity changes, bagged items, and out-of-stock marks show up for everyone on the list.
That visibility cuts duplicate staples and awkward “I thought you got it” moments. It also makes shared runs fairer — you can see what each person contributed before someone heads to the store. Up to three people can edit the collaborative cart at once, on iOS or Android.
If your house has been looking for a split grocery shopping list that actually syncs, start a shared cart, invite your roommates, and keep one household list instead of three half-finished chats.
