Aislemath: Grocery Calculator

Tired of typing the same item ten times? Aislemath is a grocery calculator built around the way you actually shop: enter the price once, tap + for quantity, and see the real checkout total before you reach the register.

ADD IT ONCE, WITH THE QUANTITY
• 10 cans of tuna at $1.80? Enter $1.80 and tap + nine times. Done.
• Every row shows unit price × quantity and the line total.
• Tap a row to edit. Deleted by mistake? Undo brings it back.

THE REAL TOTAL, NOT A GUESS
• Buy 1 get 1 and buy 2 get 1 deals are counted per item.
• Percentage discounts, including stacked ones (30% then 10% = 37% off).
• Add your sales tax rate once and the cart total includes tax.
• See how much you saved on every trip.

SHOP INSIDE YOUR BUDGET
• Set how much you want to spend. A bar shows what is left as you add items.
• Over budget? The total turns a warning color so you can take something back before checkout.

DISCOUNT CALCULATOR
• Original price, discount, extra discount, BOGO and quantity in one screen.
• Final price, price each and the amount you save.
• One tap sends the result to your cart.

UNIT PRICE COMPARISON
• Compare two or three products by price per 100 g, 100 ml or per piece.
• Works with g, kg, oz, lb, ml, L and fl oz.
• The cheapest option is highlighted, with how much cheaper it is.

SHOPPING HISTORY
• Tap Done shopping to save the trip.
• Check past totals against your receipt, share a trip as text, or load it into the cart to shop again.

HOME SCREEN WIDGET
