TriTab Calc: Multi Calculator

Free for a limited time. A clean, ad-free calculator that keeps three calculations at once. Reuse past results and calculate tax totals in one tap.

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.
