UltraCalc

UltraCalc is a practical calculator built for tradespeople and anyone working with repeated measurements.

Use the familiar calculator for everyday arithmetic, or switch to worksheet mode to organise multiple measurements and see a running total.

Features: • Area, perimeter, volume, linear length and quantity worksheets • Automatic unit conversion between millimetres, centimetres, metres, feet and inches • Dimension-aware square and cubic conversions • Named measurement rows for clearer jobs and estimates • Parenthesis subtotals shown beside each completed calculation • Calculation history stored locally on your device • Adjustable decimal precision, themes and optional haptic feedback • Responsive layouts for iPhone and iPad • No account, advertising, analytics or cloud sync

UltraCalc stores settings and calculation history locally on your device. Results depend on the values entered and should be checked before use in quotes, ordering, construction or other professional work.
