What’s New

Version 1.9

- The decimal and thousands separators are now compliant with each country's locale.

- An in-app settings screen has been added. As a result,

1. Tap/click feedback can now be specified.

◆Useage

There are four types of units to handle: days, hours, minutes, and seconds.
The unit days, hours, minutes, and seconds are each represented by one letter. It corresponds to the button on the calculator.
"d" : days
"h" : hours
"m" : minutes
"s" : seconds

The following four arithmetic operations can be used to calculate the time. Remember to enter the unit.

1. Addition ex) 1h 25m + 2h 10m = 3h 35m

2. Subtraction ex) 1h 25m-2h 10m = -45m

3. Multiplication ex) 1h 25m × 3 = 4h 15m
(The multiplicand has no unit)

4. Division 1 ex) 1h 25m ÷ 3 = 28m 20s

5. Division 2 ex) 1h 25m ÷ 28m 20s = 3.000
(Fixed to three digits after the decimal point)

Of course, you can also calculate continuously like a normal calculator.
ex) 1h 25m + 2h 10m - 58m = 2h 37m

You can also convert units to days, hours, minutes, and seconds.

 ex)1d 2h 3m 5s = s 93785s (to seconds)
m 1563m 5s (to seconds and minutes)
h 26h 3m 5s (to hours and seconds and minutes)
d 1d 2h 3m 5s

Press the same unit key to switch the display.
(Fixed to three digits after the decimal point)

 ex)1d 2h 3m 5s = s s 93,785.000s (to seconds)
m m 1563.083m (to minutes)
h h 26.051h (to hours)
d d 1.085d (to dayss)

Forgetting the unit can result in errors.
In that case, press C (clear) or ← (backspace) button to correct.

 ex) 120s + 32 = Error
       ← s = 2m32s
  (120s + 32s = 2m32s)


The display of this app has two rows, the calculation formula is displayed in the first row and the input data or the calculation result is displayed in the second row.
When you start the app, the current local time is set on the second row of the display. (Format is "24h59m59s")

Tap the display of this app to copy the contents.

The function of the CLEAR button depends on the number of times it is pressed continuously.
The first time is cleared second row of display, the second time is cleared first row of display.
For the third time, the current local time is set in the second row of the display.


Please use it conveniently.

Mr J Driver ,

OTR Truck Driver.

This calculator is very helpful when calculating my Driving Logs. It’s all about the time and being accurate which is crucial.
I would like to access the darken out version. I’m not sure of how to bring the night version up. Any guidance would be appreciated.

Developer Response ,

Unfortunately, there is no way to switch dark-mode at app individually since this setting is according to the system mode.
If system is getting into dark-mode, this app is also getting into dark-mode automatically.

Thank you for review.

Ok but

Will do fractions if a second but you need to tap S after = to display them. Tedious data entry. Must specify H, M, S for each digit. I wish we could assume 5M 2 meant 5 minutes and 2 seconds without having to enter the S. Just more jumping around on the keyboard to enter times than necessary.

But, good customer service and response from developer.

Developer Response ,

Thank you for your review.

You’ll see the fractions of your result by tapping S (or M or H) twice.

Since there is only S after M, the unit can be omitted. I will improve them in the near future.

MisterGreggy ,

Should use a colon : instead of point .

This app does exactly what I needed, simply and cleanly. One minor thing, time is marked with a colon, such as 2 minutes and 40 seconds being written 02:40
