Shopping budget tracker
Keep a running total as you shop and stay on budget.
How it works
Each line is quantity × item price. The running total subtracts your voucher, limited to the basket subtotal so it cannot make the total negative. Item count includes quantities. Green means below 80% of your budget, amber means 80–100%, and red means over budget. Tap a basket line to edit its quantity. Clear basket keeps your budget; Reset clears the basket inputs. Weekly food records are kept separately.
Your last inputs are remembered on this device when browser storage is available.
