About this app

Money between two people shouldn't be complicated.

OpenTab is a shared running tab between you and one other person — your partner,
your business partner, your brother. Open it, see the balance, see what was
added, log something new. That's it.

No more "I think you owe me from last week." No more scrolling through bank
statements. No more awkward conversations. Just a number — green if you're owed,
red if you owe — updated the moment the other person logs something.

——

HOW IT WORKS

One of you creates a tab and invites the other. From that point on, every expense
either of you logs updates the balance in real time. You both get a notification
the moment something is added. When you're square, hit Settle Up and start fresh.

WHAT MAKES IT DIFFERENT

OpenTab isn't Splitwise. It doesn't split bills between six people, scan receipts,
or connect to your bank. It does one thing — tracks who owes who between two
people — and it does it better than anything else out there.

No categories. No receipts. No group dynamics. Just a clean, shared tab.

——

PERFECT FOR

- Couples tracking shared groceries, dinners, and household costs
