Not a time clock like any other:

Save your time and calculate your working hours precisely in just a few moments and thus control your employer.

Keep yourself up to date on the monthly gross and net income. This way you avoid nasty surprises at the end of the month.

Convert your calculations to PDF and share them, for example with your employer. (Access to the device memory is required to save the PDF. From Android 10, the PDF files are saved under Android/data/com.appvision.stechuhr24/files. With older versions, they are saved directly in the internal device memory.)

The design of the app is self-explanatory and easy to understand.
