Have now decided to cancel my Garmin order and get a HRM Chest Strap instead to use with my iPhone 5S and bike apps. I can always get a bike computer later. I'm considering getting the Wahoo Tickr HRM because it's Bluetooth and ANT+ compatible (if I did decide to get a Garmin Edge 500 later).

Just wondering if it's possible to pair my Bontrager Duotrap S ANT+ / Bluetooth speed and cadence sensor and the Wahoo Tickr HRM simultaneously to my iPhone 5S via Bluetooth 4? Or do I need to also buy an ANT+ Adaptor to pair one while I pair the other via Bluetooth?

There are so many apps out there. I just want one that records my route and where I can see my speed / cadence and heart rate. What do other people use?
