I'm looking for a combination of an app like RunKeeper that tracks my running speed, with an app (+hardware?) to track my heart rate.
I'm currently running with RunKeeper (to track my speed) and also wearing an chestband+wristwatch (to track my heart rate). It would be nice to get rid of the wristwatch, if there's some app (and chestband receiver hardware?) to combine the data.
I've seen some apps that only do heart rate monitoring, but I don't want to switch between 2 apps while running.

Runtastic has a solution for heart-rate sensor bands communicating with the Runtastic apps (which are similar to RunKeeper) via a sensor key which is attached to the iPhone: http://runtastic.com/en/sensors
The dongle is as expensive as for the Digifit, but the app is a lot more affordable.
