I'm sure I speak on behalf of everyone who is amazed by this app.
You guys are awesome!! You're geniuses who thought this up in 2007 when Geotracking was still in it's beginning stages.
With a few tweaks, you guys can make this app beat any app out there whether it's free or not.
For example, I use the Nike+ with my iPod to track my workouts. However, the Nike+ cost $30USD and the iPod cost $145USD.
Adidas has their own version, which costs $130USD.
And the greatest thing of all, yours is FREE.
Everything that Nike+has, SmartRunner already has.
Adidas has a heart monitor, but I can care less about that.
The only disadvantage about SmartRunner is GPS. I mean, GPS is great to "map" your track on BingMaps. However, having GPS is also going to hurt you. For example, can't use SmartRunner if you're in a gym or wherever you don't have GPS reception.
So, Outdoors, I give SmartRunner an "A", Nike+ and Adidas a "B". Indoors, I give SmartRunner a "C".
Of course, that's not your fault at all. ANY GPS device or app is limited to the same disadvantage.
Overall, I am very impressed with this app and I see myself using it all the time, not just to track my "runs".
Keep up the wonderful work, fellas.
