Need to update key for iPhone – Jog Log - GPS Running, Walking, Cycling, and Workout Tracker Review

I would have given this 4-5 stars, but on their info to buy the key that will speak to heart rate monitors (i'm hoping it will speak to my Reebok, don't know for sure yet) it only sells a key for the old port on the iPhone 4. Help!!
