Create an Iphone and Android app for running/biking

Looking for a developer to build a running/biking application similar to Runkeeper, Endomondo and the attached app. Please see attached images for examples. Must be able to track routes,heart rate (max and average heart rate throughtout the run/ride) distance, average pace, calories, time. Must have the ability to integrate/connect to Bluetooth 4.0 wireless devises that track heart rate. Should be able to keep historical stats such as routes run by date, how far the run/bike ride was, total time, average time, max heart rate, average heart rate, max pace, average pace, max speed and average speed, elevation up, and elevation down. Should be able to show graphical statistics such as completed versus goal and month to month average speed, distance, time, calories etc. Should track stats for both running and cycling. Should have flexibility to integrate with third-party devices such as Runkeeper, Strava, Endomondo, iHealth and so on. Should allow you to compete against your best time. This should be illustrated by showing your pace compared to your current running/cycling time in graphical format (like two dots on a line or map) Should be able to record x,y, and z coordinates every x amount of feet to measure distance and elevation. Should allow two or more users to race against each other at the same time. And each user should be able to see how far or fast the other users are running/cycling (by split screen or a graphic that shows all runner/cycles on the same distance/timeline. Users should have the ability to challenge other runners/cyclers to a live run. Please see attached images of the type of data, graphics needed. I need to see proof that you have developed similar apps before.
