GpsCronos is an application that lets you measure time, distance, height and other data from your routes.
You can send data by email as well.
It is designed for jogging, but you can use in any situation, such as walking, cycling, ski or any other activity you choose.
Compatible with multi-tasking so you continue to receive data when the device is locked.
Go out and run, lock your iPhone, and GpsCronos capture your data ... ... while you dont stop!
WARNING: ¡¡¡ Continued use of GPS running in the background can dramatically decrease battery life !!!
