Running without iPhone makes Apple Watch inaccurate

Runkeeper is one of the first big-name running apps to offer full watchOS 2 support, which means you can log a run on your Apple Watch even if you leave your iPhone behind.

The Apple Watch’s built-in Workout app has always offered this feature, but it is new for third-party apps. I had never tried it before, but Runkeeper got me curious. So I left my iPhone charging at home, put on a pair of Nikes and went out for a run.

Why you may run into trouble if you try to switch running apps

Using a running app to log your workouts is a great way to track your progress and stay motivated. But have you considered who actually owns the workout data you are logging?

If you ever decide to switch apps, you might be in for a surprise. While some services, like Strava, make it easy to transfer your data, with others it can be difficult or even impossible.

Smart sport glasses want to be Apple Watch for your head

You rarely see Google Glass anymore, but if Recon Instruments has its way, you’ll be seeing plenty more head-mounted displays in the future.

The Recon Jet, launched Thursday, is a pair of smart eyeglasses for sporty activities like running and biking. Bristling with sensors, the device shows all kinds of biometric data and social stats on its tiny heads-up display. Paired with a smartphone, it can take pictures and video, send and receive status updates, find friends and family on the piste and much more.

But sports is just a start. If Recon is successful — and that’s a big if — we may be seeing smart glasses in a lot more places. Recon is betting hard that the face is the place for smart wearables.

As a guy running upwards of seven miles a day to get in shape for his imminent nuptials, Runkeeper is my favorite exercise tracking app, but you have to consciously remember to use it. But Runkeeper now has a new trick up its sleeve: Breeze, an activity tracker that taps into your iPhone 5s’s M7 motion processor to subtly guide you into living a more active life.
