ThemeCalc: Math & Calculator

Calculate fractions, work through scientific math and find polynomial roots in a calculator you can make your own.

Start with free calculator tools and included themes. No banner ads or automatic ad interruptions while you calculate.

MATH THAT'S EASY TO READ
• Enter fractions, roots and powers in textbook-style notation.
• Switch between exact fractions and decimal results.
• Use trigonometry, degree and radian modes, logarithms and factorials.
• Handle everyday arithmetic and percentages with a clear basic keypad.

A CALCULATOR IN YOUR STYLE
Preview themes before choosing. Explore metallic keys, paper textures and luminous designs. Browse a carousel on iPhone or a spacious theme grid on iPad. Additional themes are available through optional purchases.

POLYNOMIAL EQUATIONS
Find polynomial roots in Math Lab, review the results and reuse a value in your next calculation.

PROGRAMMER TOOLS
Work in HEX, DEC, OCT and BIN. Use bitwise operations, shifts, rotations and configurable bit widths, and inspect individual bits.

PICK UP WHERE YOU LEFT OFF
Revisit calculation history, copy results and continue from a previous calculation. Set sound and haptic feedback to suit the way you work.

ROOM TO WORK ON iPAD
A dedicated workspace brings sidebar navigation, recent calculations and multi-column tools. Layouts adapt to portrait, landscape and smaller windows.
