Strava
Strava is a sports tracker mobile app and website. There is an emphasis on cycling but other sports, like hiking, running and skiing can be tracked as well. Strava will keep other data separate from cycling data.
Strava has automatic mapping and elevation tracking. Users can highlight their favorite streets or routes and Strava will note those for future rides.
Strava tracks heart rate and mileage from GPS devices. Strava can also assess power output by estimating wattage based on terrain covered. Users can compete against each other and follow their cycling community. Finally, Strava tracks equipment usage.
