Should you actually build your own Splitwise?

Our verdict: Yes. Splitwise's core logic is well-defined and buildable. Build if you want a private group expense tool; keep Splitwise for receipt OCR and multi-currency polish.

You want a simple app without ads or Pro upsells
Equal and custom splits cover your use case

Stick with Splitwise if

You rely on receipt scanning and automatic categorisation

What is Splitwise?

Splitwise helps friends and groups track shared expenses and figure out who owes whom, without awkward spreadsheets.

How difficult is it to build your own Splitwise?

The core splitting logic is one of the more buildable apps on this site. Polish features like OCR and currency add moderate complexity.

Is building your own Splitwise worth it?

Yes, if you want a private tool for a recurring group (roommates, trips). Splitwise's free tier is also strong, so building is about control and customisation.
