Store description excerpt
A three-tab calculator that lets you keep multiple calculations going at the same time. The A, B, and C tabs each work as an independent calculator. Switch between them without losing your current expression or result. Use A for the pre-tax price, B for the tax-inclusive total, and C for the discounted price—all without writing down intermediate numbers or clearing your work. Ideal for estimates, invoices, shopping, splitting bills, comparing unit prices, and everyday calculations. ■ Three Independent Calculators Switch between A, B, and C with one tap. Each tab keeps its own expression and result, so you can work on three calculations in parallel. ■ Calculation History Review your recent expressions and results. Tap a history entry to copy its result instantly. ■ Copy and Paste Tap the result display to copy or paste. Touch and hold to clear it. Moving numbers between the calculator and other apps is quick and easy. ■ Tax Calculation Calculate tax-inclusive and pre-tax prices with a dedicated button.
