As indicated below, this is my fourth posting. I am delighted to report that the problems I describe below have been fixed. As a result, this wonderful app is fully functional. I now regularly take it on my rides so that my Pebble keeps me informed of my speed and distance, and with a couple of pushes both the weather and my heartrate. It is very handy. This is my third post/review. I love this app but it disconnects when a notification comes in. I blamed the app. More research has shown the problem lies with Apple. They have a major incentive to fix it since it interferes with the use of iPhones in cars, so the fix should be soon. It is, simply said, better for biking than anything else out there. I took my WeatherRun out for a spin yesterday and was mightily impressed. It tracked my rate and distance wonderfully and gave me all sorts of data at the end of my ride. I would like more info on some of the details of the app and there are a few improvements that can be made, but overall this is an app that provides meaning to the Pebble Smartwatch. If it had an HRM I wouldnt need another training app. Well, Ive now used it many times. Alas , as I say above it is an app that I desperately would like to use. But I have not been able to keep it working for more than 5 miles. That doesnt hack it for a biker. Ive tried all sorts of things but I cant keep the app and my Pebble talking to each other. Please fix it! And add altitude as well.
