Family shopping, in sync
Build your shopping history.
Know what's running low — before you do.
CartPatt is one shopping list your whole household shares. Everyone sees what was just bought, what's still needed, and what's about to run out — no group texts, no guessing.
iPhone beta is open now via TestFlight. Android is still in testing — want in sooner? Sign up for early access and I'll add you as a tester.
How it works
Four taps from a shared list to a household that never double-buys.
STEP 1
Start your family group
Create a group, or go solo, then invite your family in.
STEP 2
Add to the shared list
Anyone in the family can add what's needed, from anywhere.
STEP 3
Check off as you shop
Every purchase is saved to your family's history automatically.
STEP 4
Get nudged in time
CartPatt learns the pattern and reminds the family in time.
Not just another checklist
Most shared shopping list apps forget an item the second you check it off. CartPatt keeps the record — and does the math.
It remembers for you
Every completed trip is saved to the calendar, so the list knows what your household actually buys — and how often.
No more duplicate buys
Add something that was bought three weeks ago and CartPatt says so, right in the list. The second pack stays on the shelf.
Quiet by design
No feeds, no chat, no noise. One shared list, one history, and a nudge only when something is running late.
Calendar —
see the history
Every completed trip is saved, so the family can see what was bought and when.
Stats —
know what runs out next
CartPatt learns your buying rhythm and flags what's early, due, or running late.
Settings —
keep everyone in sync
Manage your family, invitations, and shopping reminders in one simple place.
One list. One history.
No more buying it twice.
