Actual Working Hours / Differential Comparison Management App

"Time for preparation before work isn't being counted..." "With 15-minute rounding down, the daily fractions become unpaid work..." Do you have that kind of frustration?

This app records your "actual working hours" in 1-minute units and instantly visualizes the "difference" from your company's calculations at a glance.

It's incredibly simple to use! Just tap a button when clocking in and out, and the real-time timestamp is automatically saved. Based on your set standard hours (for example: 9:00 AM to 6:00 PM), it accurately tallies early arrivals and overtime down to the minute. Even if you forget to clock in on a given day, you can freely edit or input data anytime from a month-long calendar, so you're covered.

And here's the best part—the "verification feature" after your paycheck arrives the next month! Simply input the working hours your company provided, and the app automatically calculates "cut time and unpaid overtime" as "+◯ hours ◯ minutes." You'll instantly see an estimate of how much money you're losing.

Data is semi-permanently saved in your browser & CSV export is also available. No complicated settings whatsoever! Don't overlook the big losses hidden in "just a few minutes"—protect your precious time and money!
