Turn your iPhone into a cyclometer

I just replaced an ancient Cateye Micro bike computer with this Blue SC hardware. At present, I am using this product with the Cyclemeter app, which I find to be the most flexible in terms of interface customization. So far, I really like this combo. Installation was no more or less complicated than for other cyclometer/sensor installations. Wahoo provides two mounting options for the sensor pickup -- a rubber band and zip ties. At first glance, I liked the rubber band idea. Setting up the app for my new sensors was a piece of cake. The iPhone detected them right away via Bluetooth and automatically took care of the pairing. However, the setup and detection process varies from app to app, so I can't comment about how this process works for anything but Cyclemeter. I am now looking at adding the protective case and extended battery options, and maybe even another sensor and case mount for my mountain bike. I Like the idea of being able to use my phone for multiple bikes.
