What's new?

⏱️ Time Calculator

The Time Calculator is a full expression-based tool for time math. Not a date-difference picker, but a genuine calculator that lets you chain additions, subtractions, multiplications, and divisions across any mix of time units, exactly the way you'd use CalcKit's other calculators with numbers.

  • Mix and match units freely: year, month, week, day, hour, minute, second, and millisecond can all appear in a single expression. Units can even be chained implicitly without typing a + between them (e.g., 2 hour 15 min).
  • Smart math that respects real-world time logic: Time ± Time produces a normalized time result; Time multiplied or divided by a plain number scales the duration up or down; Time ÷ Time gives a ratio. Nonsensical operations (like squaring a duration) are automatically blocked so you can't get garbage results.
  • Percentage support: use a percentage as a scalar fraction or as a percentage of a running total.
  • One-tap unit breakdown: tap the result to open a popup showing that same duration converted into all 8 supported units at once (years down to milliseconds). A small conversion icon on the result hints that it's tappable.
  • Long-press the result to copy it straight to the clipboard.
  • Full calculation history: the last 50 entries are saved; tap any of them to restore and reuse the expression.
  • State is fully preserved even if the app is closed mid-calculation.
  • Can be pinned as a home-screen shortcut like the app's other tools.

🔧 Bug Fixes & Improvements

  • Toolbox scroll position: Fixed the Toolbox home screen jumping back to the top when returning from a tool. Your position is now correctly restored.
  • Library updates (Android & Web): Updated underlying libraries for improved reliability.
  • Minor bug fixes (Android & Web): Fixed several minor bugs and visual glitches.

Flight connections, overlapping shifts, project countdowns. It's the kind of time math that comes up more than you'd expect, and somehow never has a proper calculator behind it. Now it does. CalcKit v8.2.0 is available now on the Play Store.
