Time Calculatorby Cardamon

Release notes

What changed in the Time Calculator app. The web version shares the same calculation engine, so improvements to the math land in both.

2.4.0

Customisable keypad, saved history, and quick result actions

  • Customisable keypad: choose which time-unit keys appear with one-tap presets (Standard, Stopwatch, Media, Hours & minutes, Calendar, Everything) and a live preview, in Settings → Keypad keys.
  • Calculation history: results are saved on your device. Add a note and tap an entry to reopen it in the format it was saved with.
  • Tap a result for quick actions (copy, change format, rate, share); long-press to select text.
  • Redesigned rate (“Per”) calculator for clarity, plus new result formats including milliseconds and Hour·Minute·Second·Msec.
  • Smoother resizing as you drag the display and keypad split, with dark-theme divider and accessibility fixes.
Earlier releases

The foundation

  • The shared calculation engine: add, subtract, multiply, and divide durations from years down to milliseconds.
  • Multiple result formats so the same total reads as hours, days, minutes, or a full breakdown.
  • The rate calculator for working out an amount per time interval.
