My program works as follows: With a GPS connected to a small computer, the current position is checked against a database of client positions. When a stable position is found, the time and position is recorded. When I leave I have the option to input my work. Again time is recorded. As a side affect my log book for TAX purposes is also kept. At the end of the month, a report is generated with all the information. It is then easy to copy and paste the information into my invoicing system.
What I want to do next is to record my position with speed on an ongoing basis so that I can submit the evidence in a court of law next time I receive a speeding fine.
Since the beginning of this year (2013) I am developing the ANDROID version of this program. It has more features than the program above. Currently called "Consultant's Logbook", it is currently in beta test phase and it should be available by the end of October on Google Play.
A 45 day demo version of the program can be downloaded
If you like what you see, you can buy the program.
