Most couples still juggle two notes apps or a pinned text thread. That falls apart the moment both of you edit at once — a second jar of peanut butter, or almond milk added from the couch that never shows up in the store.
A shopping list for couples should be one live cart. When you add eggs after work, your partner sees them before the dairy case. When they bag bananas, you see the item leave the list. CartTogether is built for that — not a merge-later checklist.
You can shop together or split the run. Mix iPhone and Android. Reuse weekly staples so you are not rebuilding the same cart every week.
If you have been searching for a shopping list for couples or a shared grocery list app for two people, start a cart in CartTogether and invite your partner once.
