Automatic Stop Detection

We love a good technical challenge. Whether it is how to race against yourself (showing your best, median, and worst runs on a map in real time), how to tap into the earphone remote so you can stop and start our app while the iPhone stays safely in your pocket, or how to dynamically filter errors out of GPS data, we love hard problems.

This is why we had a blast coding our newest feature, automatic stop detection. Just tap More, then Settings, and turn on Stop Detection. And it just works. Whenever you stop, our app analyzes the incoming GPS data, and then rolls back your elapsed time to when the stop started, and attributes the time you are stopped to the stopped time display.

While you are underway, stopped time is shown underneath your elapsed time. And then after your workout is done, you can see the summary in your detailed workout data. You can even edit the workout and turn off stop detection to see what the time would have been otherwise.

Because GPS accuracy varies, using Stop and Start or our remote control will provide the most accurate results possible. But we’ve been testing and refining it for months now, and we’re quite happy with the results. We hope you are, too!

Thanks to the hundreds of people who wrote to us requesting this feature, your input raised automatic stop detection to the top of the list.

On to the next big technical challenge!
