Clocky Dockie will help you track your working hours easily. The goal of this app is not to replace your accountant, but just to simplify the process of tracking your hours and pay without the effort.
Simply set your job location and it will remind you to clock-in or out.
Track your hours, pay, tips + comments (if you have any).
Set a predifined shift duration and get a reminder to clock-out whenever the shift is over.
Edit shifts manually.
Exports shifts via email.
I actually built this app for my own usage after I tried so many times to write down my own hours, and always failed to do so steadily, what makes the whole thing pointless.
I hope this app will help you like it helped me :)
