This Android app will run on the Samsung Galaxy Tab 10" tablet. Basically, the user selects a location from a list, starts a session, and from time to time records two numeric values. Each entry also captures lon/lat from the onboard GPS. User ends session. At any time when not in session, user can sync collected data to a remote web server (e.g. to a MySQL db). I have a Windows based program that does all that minus data synchronizing, fully working, that you can use to see what I need. I also have working Android source code written for a similar app that you can reuse. I have the server where to store the data. I am available on Skype to discuss details. Budget negotiable.
