Runtastic

Hi there. Yes, I'm using it only the last week, and I'm very happy with the app.
It shows me everything I want to know, like distance, time, speed and a map of my route. Yesterday I went out with my rollerskates, and I just changed the setting from 'run' to 'skating'. Easy as that. Lots of activities in there.

I'm going to buy the PRO version, because I want to run with a Heart Rate Monitor.

Also it puts in the results of my session in MFP, so I can see immediatly what is the effect on my daily calorie-intake. Great app!!

I've been using it for a few months now, and really like it. It is easy to use and keeps track of what I want. I use it mostly for running and walking but have also used it for biking. I have the free version but am thinking about upgrading to the pro so that I can hear the miles as I run along with my pace for that mile.

I just recently got a smart-device, so I went through and tried a number of running apps and Runtastic was the one I liked best, as far as functionality and stats. (There are apps I didn't try, of course, and I can't remember all the ones I did, but I consistently found myself thinking "Runtastic did this better..." or "Runtastic had this feature, and [whatever] doesn't.") I have the free version because I haven't found myself needing the pro features.

So my vote is that I like it!

You need to buy a compatible heart rate sensor and wear it with you to detect your heart rate. I use Zephyr HxM Bluetooth.

runtastic will then show your heart rate & heart rate zone (based on your maximum heart rate).
It's useful for me as I can run at a target heart rate zone/range. Or I know i'm running too hard if my heart rate is pumped up too high.

I believe the free will link to MFP too.
