Jason Jacobs, the founder of the Runkeeper app has announced the launch of the latest updated GPS fitness-tracking app for Apple Watch, which was “rebuilt from the ground up” according to the founder. Even if the Runkeeper app has been around for months and available for Apple Watch, you still needed to carry your iPhone with you, for proper GPS tracking.With the launch of the Watch OS 2.0, Runkeeper has been updated to work on your Apple Watch, while your iPhone is left at home. Although the watch doesn’t have a GPS included, the Runkeeper app will still be able to track your distance, all while still showing you your heart rate, time and average pace. The updated app will also allow you t select your activity type from your Apple Watch and recaps with run stats will be available at the end of your exercise.
As for how Runkeeper will keep track of distance without actual GPS, no proper explanation has been given. It is probably a combination between Wi-Fi data and the M8 motion coprocessor that Apple Watch has included. This idea seems plausible because Jacobs has said that the accuracy of the app will depend on the location, buildings and even weather conditions, also the accuracy seems to improve over time if it is constantly used without relying on the iPhones GPS.
The improved Runkeeper app is what its users have been asking for, as iPhones are getting bigger it is harder to carry them around while exercising. An accurate fitness-tracking app that work on the Apple Watch is now available at the costly price of $350.
