Tapewise is a calculator that keeps a tape of everything you work out, and lets you change any line later.
EDIT ANY LINE, THE WHOLE TAPE UPDATES
Every calculation becomes a numbered row. Tap a row to change it and every row that uses it recalculates instantly. Refer to earlier rows (#2) or give a result a name (rent, shirts) and use it in later lines.
SEE HOW EVERY ANSWER WAS WORKED OUT
Tap any result for a step-by-step breakdown that highlights the part of the sum each step comes from.
MONEY TOOLS BUILT IN
• Tip and split: bill, tip and number of people
• Discounts: take 20% off, then another 10%
• Tax: add it, or find the price before tax
• Unit price: see which pack is really cheaper
• Currency: daily European Central Bank rates, kept for offline use
Every tool adds an ordinary line to your tape, so you can edit and check it like anything you typed.
EXACT DECIMAL MATH
No floating-point surprises: 0.1 + 0.2 is 0.3, and money adds up to the cent.
