krish-bhavsar19/group-expense-management ? reverse-engineered prompt

Build me a full featured group expense tracking app where people can sign up with email and OTP or Google, then create groups, invite friends with a link, and keep track of shared costs together.

I want a clean dashboard where users can add, edit, and delete expenses, upload receipt images, and split bills evenly or by custom amounts. It should also support subgroups inside a main group so smaller sets of people can track their own spending separately.

Please include a smart expense input option where someone can type or speak something like, “I paid 50 dollars for pizza for everyone,” and it turns that into an expense automatically. Also add a settlements screen that shows who owes who and helps people settle up with as few payments as possible.

Make it feel modern and polished, and if you need current docs for any integrations, look them up online.
