Split the month,
not the receipt.

CommonCard watches the accounts you share and keeps track of what is yours, theirs, and both. At the end of the month you get your total on each account.

Not a running tab

Other apps treat you like roommates. Every receipt gets divided.

With CommonCard, you tag as you go, and each account totals up at the end of the month.

Three steps

It gets easier every month

1

Add your cards

The checking and credit accounts you already share. Purchases show up on their own.

2

Tag purchases

As yours, theirs, or shared. Turn on "Remember this selection" and it does that store for you from then on.

3

Month end takes care of itself

Every account shows your total, already worked out from what you tagged.

Pick your split

Down the middle, or not

60/40 if one of you earns more. Any number you like. It applies to the month, not to each purchase.

Say you go 60/40. In September you shared $2,660 on the joint card, and $359 of it was just yours.
Your share: $1,955. That is the whole conversation.

Get one wrong? Change that purchase and both your numbers update.

Both of you

Same numbers, both phones

Invite your partner and you are looking at the same thing, live. Tag something on your phone and it is tagged on theirs. No exports. No Sunday night sit-down.

Questions

Before you download

Do we both need it?

Yes. One of you adds the accounts and invites the other.

We do not split things evenly.

Pick any number. 50/50, 60/40, 70/30. It applies to the month, not to each purchase.

What if something gets tagged wrong?

Fix that one purchase. Both numbers update right away.

Is this a budgeting app?

Not really. It answers one question: what each of us owes on each account. Plenty of couples run it next to a budget app.

Android?

Not yet. iPhone only.

Why does it look like a normal iPhone app?

On purpose. Nothing new to learn.

Stop settling up

Add your accounts and see your total on each one.
