Percentage Expert

Percentage Expert is built around one narrow task: doing percentage math without making the user fight with the formula. By our assessment, that makes it handy for quick discounts, markup checks, tax-style calculations, and other small finance chores. The limit is obvious too, because a percentage calculator is only useful when that is the question on the table. In practice it should feel fast and plain, with a small interface and little room for confusion. It sits alongside other calculation helpers rather than broader finance apps. Percentage Expert makes sense for people who often need percentages for shopping, work, or basic budgeting, and it has little to offer once the problem turns into real accounting or investing.
