About this app

A simple calculator app that adds times given in hours and minutes. It helps with the recording of machine running times, with the addition of flight times in your pilots' flight log, or your driving times as a truck driver.

This user interface is designed to be simple, minimalistic and functional. The app contains no advertising and does not spy on you. The program is 100% Open Source and written without commercial interest.

Works well but would be a lot better if there was a now button. When you hit now it would put in the current time then you could do your adding and subtracting from there. Instead of having to manually input the current time.

Thank you for the review. We considered your suggestion, but eventually decided not to implement it because we want to keep the app as simple as possible. I understand that this is not what you wanted, and ask for your understanding!

Great app. Simple and purpose focused, so don't have to hit buttons like "min" and "hours", displays history as well so you don't loose your place. Very easy to use, fast and no ads or gimmi ks.

Excellent app. Very quick and simple to use. You do not need to input a fullstop between the hours and minutes, just punch in the number and press the +
