About this app

Decimal Fraction Tool is a compact calculator for everyday numeric conversions. Enter a decimal, fraction, mixed number, or percent and instantly see equivalent decimal, fraction, and percent forms. Switch to Bases mode to convert integers across binary, octal, decimal, and hexadecimal. Use Scientific mode for quick expressions with common functions such as sine, cosine, tangent, logarithms, square root, powers, and parentheses.

The app is built for students, makers, tutors, hobby electronics users, and anyone who needs small conversions without a bulky calculator. Results can be copied to the clipboard, saved to local history, reopened in detail, and cleared when no longer needed. Dark mode and cache controls are included on the My page.

Decimal Fraction Tool works offline, stores calculation history locally on the device, does not require an account, and does not request network permission.
