Make a calculation. Change a number. Keep your train of thought.

Xidents Calc combines an editable calculator with practical tools for study and everyday work on iPhone and iPad. Its silver expression display keeps your calculation and result clear in light and dark appearances.

EDIT WITHOUT STARTING AGAIN Move the cursor, select part of an expression, insert parentheses and undo changes. Preview results as you type, then save calculations to searchable history with pins and notes. Copy or share results when you choose.

SCIENTIFIC TOOLS Work with trigonometry, logarithms, powers, roots, factorials and degrees, radians or gradians. Search functions and templates for fractions, combinations, permutations, prime factors and coordinate conversions. Explore statistical datasets and regression, compare numerical expressions in Verify, and store named values for reuse.

EVERYDAY CALCULATIONS Use time arithmetic and number bases alongside unit, cooking and currency conversions. More includes practical financial tools such as compound interest and rent conversion. Choose percentage rules, operation order and number formatting to suit your task.

DESIGNED FOR YOUR DEVICE Adaptive layouts support smaller iPhones, larger iPhones and iPads. Switch between light and dark appearances and adjust available display preferences.

No account is required. Core calculations work offline. Currency rates require an internet connection to refresh; cached rates show their date. Your calculation contents stay on your device unless you choose to share them. Advertising and online-service data practices are explained in the privacy policy.

This is a numerical calculator, not a symbolic algebra system or a claim of complete equivalence to a particular physical calculator. Phone use in exams depends on the institution’s rules.
