Ice Skating Lap Tracker

跟踪的次数，你周围的室外溜冰场滑冰

This app uses GPS to track the number of times you skate around a rink. It works best on outdoor rinks (make sure your GPS settings are set on high accuracy!).

First, you calibrate the app by going around the rink once. Then, future laps are recorded automatically.

Some rinks are recognized automatically and do not require calibration such as Lasker and Bryant Park rinks in New York City and Nathan Phillips Square in Toronto.

The app can also be used for jogging around a track.
