SpeedProof - Speedometer 0.7.8

Some people have beat speeding tickets in the past with GPS loggers, this app logs your current speed, location and so on to a GPX file as fast as the GPS chip updates the system, but unlike other GPS loggers uses cryptography to make a tamper proof log which you can use to prove your speed. I\m not a lawyer, use at own risk. For more details check out our FAQ: http://speedproof.odiousapps.com/faq.php
