I love this app! I used to run with a pedometer but since it was a relatively cheap one I was never really sure of the accuracy.
This tracks your distance and so much more. It saves your history so you can keep track of personal bests. When you reach each mile or a finish a run it tells the time difference between that run and the previous personal best.You can map out routes online and then save them to your phone. Some people are good at estimating distances, I'm not one of them. At this point I know that if I run continuously for 30 minutes I definitely ran at least 3 miles but I like to have something more accurate.
You can access routes posted by other people (nothing really great in my neighborhood, but a few a short drive away).
You can friend people and then compete against them (I've never done this as I only have a couple of friends and they are all in Europe). You can send peptalks to friends if you see that they are out exercising.
While so far I've used it exclusively for running you can use it for lots of other sports too - cycling and kayaking are popular among my friends but also team sports
You can connect to a heart rate monitor to get access all of that info too. Mine is too old to be compatible so I don't even wear it anymore.
But really it's the stats that I love. It even has some silly ones online. Since it tracks calories it also lists how many hamburgers burned. Since it tracks distance it shows your distance compared to running around the Earth, and to the Moon. Not sure how long it will take me to run around the world. I know I could do the math, but I don't want to. I'd rather just watch that number slowly increase.
I know there are plenty of other training apps out there. I started with this one as I saw it come up on one of my friends Facebook posts. You can share your stats on FB. I don't. Maybe when I get better, but not yet. Right now I don't feel like I have much to brag about.
I started with the free version and recently upgraded to the premium. Free is pretty good, but premium allows you to do interval training, which I need to do more of if I want to increase my distance.That's my next step, and I like that along with preprogrammed interval training programs, you can also create your own interval training program. I've made one that I need to try out - we'll see how it goes.
