Show HN: TabChop a truly painless way to split a tab

https://tabchop.app/overview
2•mishang•1w ago
We built TabChop because splitting a bill still feels weirdly painful. Someone downloads an app, the receipt scan is off, the UI is clunky, and half the table gives up.

After one too many dinners where the “solution” turned into unresolved requests and Venmo chaos, we wanted something that simply worked.

TabChop starts with the receipt. Take a picture, share a short code, and everyone claims what they ordered. You can watch the receipt update live as people grab their items in real time, so there’s no “who got what?” confusion.

We also store each person’s Venmo, Cash App, or Zelle info, so when the split is done it’s one click to pay. No awkward questions about who to pay or how much.

The goal is simple. No friction, no math, no awkwardness. Just a painless way to split a tab.

Hi I'm Yash, one of the developers.

Would love to hear any feedback/thoughts :)

In Korea (and probably other cultures) the whole group orders items together and shares. So the splitting math is a little different:

- Simplest: just divide total by N people

- Different subtotals for food, alcohol, and drinks

- The most complex is probably: food is split evenly, but individuals claim beverages. (And there are some cases where certain food items are also claimed.)

Usually one person is the "treasurer:" they pay the entire bill and make a chat room to finalize with other members (share a table of who owes what and maybe send payment requests)

Interestingly, KakaoTalk has a built-in feature to split bills in this manner. It's not intuitive to use, so a lot of people just do it manually.

mishang•1w ago
This is actually very similar to our implementation. The host pays the bill then users go in and either claim an entire item or split the item between multiple people. Each person is then assigned an individual bill with quick links to pay the host!

Oh~ I missed "Shared items split cleanly" in the copy. And I didn't feel like creating a new account to check it out. Would be nice if you didn't have to sign up/login. (Maybe like how a shopping cart allows creating an account at checkout)

(And I initially thought "TabChop" would be a windows management tool: split windows...)
