Timesheets

Amazing Calculator - has everything I need to calculate my timesheets easily and accurately

Give me money

That’s all they want is money. Oh and the ads. Wonderful…

Accuracy Matters

Excellent calculator for small business

Can subtract time for free

You can’t even subtract a time period from a set time unless you buy the pro version.

I knew the free version would have ads and probably some features would be locked. But I still expected the free version to have all of the BASIC functionality of a “time calculator” (i.e., add AND subtract time).

Not working

I used to be able to add between two different times. And now each time I go and use it it keeps saying invalid start time when it never did that before. And it’s only when I paid for the full version so I don’t understand how now all of a sudden it’s not working. I want my money back and I’ll take the free version again because at least the free version actually worked.
Update: I’m thought I’d give it another shot but, it STILL DOESNT WORK
