This is all done through a single tap on the widget when I arrive and when when I leave each day. While I could accomplish this through geotagging, since this is a test I’m sticking with manual for the near term.
I’ve started using an app on Android called Automate-It Pro to help keep track of my time in and out of work. Since my time is billable, I need to know when things start and stop. For now what I’ve done is added a widget to my phone that sends an email to Evernote recording the location and time in a new note categorized for my work notebook and tagged for the client.
