Jogging Partner will notify workout information (elapsed time, distance, speed, number of steps, etc.) by screen as well as voice.
By the notification of a voice, it is possible to check the data without looking at the screen during the workout, you can focus on more workout.
After the workout, workout data (date, time, distance, step count, the track data based on the GPS information, etc.) will be saved in your device, you can check at any time. (* 1)
You can backup the data to SD card and restore it from SD card, so you can inherit the data when changing phones.
Please note that continued use of GPS running in the background can dramatically decrease battery life.(*2)

(*2) You can check that Jogging Partner works in background by the badge of icon in home screen. Number of badge represents the time (in minutes) from the start of workout.
