My basic policy about GPS of 'Sound Pedometer GPS'

Many pedometer applications have the setting of foot step length and calorie calculation. But I don't like that well. Because I think these calculated values are not unclear. So this application doesn't have calorie calculation and use distance from the calculated value of GPS location data instead of the calculated value from step length. Also GPS is unstable, but even if the received location data from GPS is not correct, we can know "this is bad data" because the data plot to map. I like that more.

(However I think sometimes I want to know distance by step length when I walk an under ground shopping center at Nagoya station. This function may be added in the near future.)
