Runkeeper's Apple Watch app also gains a customizable activity screen so you can choose what's on the wearable's display during your workout. One of those stats is a new heart-rate graph that shows your BPM over the last five minutes. There's also a target pace graph that plots out a five-minute snapshot of your run compared to a speed goal you input before you get started.

For updates during your run, the app will alert you with a vibration each time to you log a mile. To give the latest version of Runkeeper a go, download it from the App Store and lace up your sneakers. Keep in mind that in order to take advantage of the added GPS abilities, you'll need to have an Apple Watch Series 2.
