How can we help?

Download the app and open it. No account or login required. Tap the "+" button on the home screen to create your first list.

Cart works on iOS 16+ (iPhone/iPad) and Android 8 (API 26) and above. Couple mode is fully supported between iOS and Android devices.

Yes, Cart is free to download. The free plan lets you create up to 3 shopping lists. Cart Pro is available for unlimited lists, recurring lists, and other advanced features.

In the app, go to Settings → Add Partner. Share the generated 6-digit code with your partner. Once they enter it in "Join with Code", pairing is complete and your lists merge.

Each invite code is valid for 48 hours. If unused, you can generate a new one. A code can only be used once.

Your lists and items are merged with your partner's. Lists with the same name are not duplicated. Your points history is also carried over.

In couple mode, lists are synced in real time via Supabase infrastructure. Changes your partner makes appear on your screen within seconds.

When your partner is viewing the same list screen, you'll see a "Partner is here" indicator. It means you're both looking at the same list at the same time.

You earn 1 point for every item you check off a shopping list. In solo mode points are personal; in couple mode both individual and combined totals are shown.

A confetti animation plays when you hit certain point thresholds: 50, 100, 250, 500, 1,000, 2,500, and 5,000. In couple mode this notification is also sent to your partner.

In solo mode, all data is stored only on your device. In couple mode, data is stored encrypted on Supabase (EU region).

In solo mode, your data is deleted from your device. In couple mode, your partner's data remains on Supabase. To delete your own data, email hello@keremcebi.co.
