Show HN: TimeCalc – A Simple and Accurate Time Calculator for iPhone/iPad/Mac
apps.apple.com
TimeCalc is a small utility I’ve been maintaining for years. I originally built it to help pilots log and calculate flight hours without the hassle of spreadsheets or clunky online tools.
Over time, it evolved into a simple and accurate time calculator that lets you add, subtract, and compare hours, minutes, and seconds — or even calculate the exact difference between two dates.
This new version was completely rebuilt for iOS 26 and macOS, with: - A clean, native interface - iCloud sync across devices - No ads, no accounts, no third-party servers - Accurate operations on hours, minutes, seconds, and dates
It’s designed to do one thing well: make time math fast and reliable. Data stays in your iCloud account, and everything works offline.
I’d love feedback especially from anyone who’s built or used similar tools. Are there features or workflows you’d expect from a native time calculator that could make it better?
