## What is Double Calculator?

Two calculators. One screen. Every calculation you need.

Double Calculator gives you two full calculators side by side — compare prices, crunch taxes, split values, and solve complex math without switching apps or losing track of numbers.

DUAL CALCULATOR
Work with two independent calculators on a single screen. Compare rent offers, product prices, loan payments, or any two values instantly. Transfer results between calculators with one tap.

VAT & TAX FOR 40+ COUNTRIES
Calculate VAT, sales tax, GST, MwSt, TVA, IVA, and BTW for over 40 countries. Your country is detected automatically — or set any custom tax rate you need. See net, gross, and tax amount at a glance.

PIN & SAVE RESULTS
Pin important calculations and label them for later. Build a list of saved results you can reference anytime — perfect for shopping lists, price comparisons, or expense tracking.

SCIENTIFIC CALCULATOR
Rotate to landscape for a full scientific calculator with trigonometric functions, logarithms, roots, powers, constants, and more.

TIPS, DISCOUNTS & PERCENTAGES
Calculate tips at any rate, apply discounts to prices, find percentage differences, markups, and margins. Everything percentage-related in one place.

PRECISION YOU CAN TRUST
Built on precise decimal arithmetic — no floating-point rounding errors. Every digit is accurate, whether you are calculating taxes or engineering values.

DESIGNED FOR EVERYDAY USE
• Clean, intuitive interface
• Works on iPhone and iPad
• No account required — your data stays on your device
• No ads, no subscriptions — pay once, use forever

Double Calculator is the everyday tool for anyone who compares prices, calculates taxes, tracks expenses, or simply needs two calculators at once.
