About this app

Win is an all-in-one utility app whose percentage calculator includes a reverse-percent mode that most basic calculator apps simply don't have, answering the question in the direction you actually need it.

Reverse percent is Mode 4: if you know that $34 is 85% of the original, Lottomatica calculates the original was $40, no algebra, no formula lookup, just two inputs and an instant answer.

This reverse mode is particularly useful for working out pre-discount prices, understanding tax-inclusive totals, interpreting data where only the final value and the rate are known, and any situation where the percentage was applied before you saw the number.

Mode 3, decrease by %, works in the forward direction: enter an original value and Lottomatica tells you the result after that percentage reduction, covering sale prices, depreciation, and cost reductions.

The number base converter provides technical utility alongside: enter any number in binary, octal, decimal, or hexadecimal and Lottomatica fills in all four values simultaneously, fully offline, no account needed.
