I play golf, I have a Samsung Galaxy S3 android smartphone. I started to use the Free Caddie app for determining distance to the green.
The problem was that the phone is hard to see in the bright sunlight and it is awkward to keep pulling out your phone to see the distance to green.
Then I discovered that the new Pebble smart watch can connect via bluetooth to the golf app. So I bought one at Best Buy. And I opened it and played a round of golf with it. Yes - it is awesome. It works.
I love the watch and the app. The watch also receives your email and your texts and can control your music. It is shiny and red and cool.
And I discovered now that it's a bike computer too. The free Pebble Bike app works great - tracking your biking mileage and speed, average speed, altitude, ascent, ascent rate and slope (beta) - even when your phone is in the zipper bag under the seat! Nothing more to buy. Wow.
They are rare. Get one right away here at Amazon or Ebay. Or try to Get one from Best Buy.
