It is possible to group the data into areas, projects and project parts. The projects are entered in advance and then just selected. Then times can be recorded for the parts and then exported later.
At the moment the data is stored locally on the device.
The data is available as Android App and for the browser.

The app is available for the web browser (mytime).

Later I would like to be able to save the web server so that I can work across devices. Then I can create the projects on the PC and stop the time on the cell phone.
