I have a very flexible work schedules but am not allowed overtime. I’ve been having a “hard time” clocking out at precisely the right time. My supervisor mentioned it to me several times much to my embarrassment. I spent a good hour looking for solutions (I refuse to do my own calculations when I know there’s a better way) until I found this. Now no matter when I clock in or how long I take for lunch I’ll know precisely when to clock out to get my 8.

Love this app but one request

I've been using this app for months now and love it. One improvement I would like to see is on the time calculator tab in addition to the the total hours to also see the hours converted to minutes. For example if the time difference is 4:00 to also show 240 minutes.

Inaccurate calculations

I've downloaded this app before and deleted because of the same issue.. I'm thinking the Creators would've updated and improved it by now.. I decided to download it again but its still doing the same thing.. After awhile of having the app it starts calculating inaccurate time... I used the app to quickly calculate my hours worked for the day to keep up with my time on my own.. I always write my time down as soon as I clock in and out every day and at the end of my shift, I use this app to precisely calculate my total hours up for that day..
