The idea

Coffee shops and small restaurants pool tips and split them by hours, often on a calculator at closing. Tip Split takes each person hours and the total, shows each share, and saves a record staff can see. It is a calculator and record, not payroll or tax advice.

PROMPT 1 OF 3

Build a mobile friendly web app called Tip Split. Start with a manager login and a Staff page with name and role, and a New Split screen with date, total cash tips, total card tips, and a row per staff member for hours worked.

PROMPT 2 OF 3

Calculate each share by hours with rounding to the cent and show leftover pennies clearly. Support optional role weights (for example, baristas 1.0, trainees 0.5). Save each split with date, totals, and per person hours and amounts.
