.  Compare isn't quite right (although Garmin does have a really strong website now for working out http:\\connect.garmin.com ) they really should be accessed by how well they work together.  Again, another plus for Runkeeper is its ability to connect to my Garmin watch and download the run directly into my profile. I doubt the Nike site does, but ARS should have looked at this for RK and SR.  Like some of the other RK users - I don't care about a fancy/flashy app on my phone. Heck since I bought my Garmin 000 a couple of months ago, I haven't even touched the app (don't need it). What I care about is the quality of the website and the tools it has for reporting and reviewing workouts. For this, Runkeeper blows them all away!  +0  I absolutely hated the GPS for real time tracking on both my iPhone 0G and my Nexus S. Bought a Garmin 000xt and that solved that. From what I've experienced, the tracking from a dedicated watch/gps unit far exceeds that of a GPS enabled smartphone.  I liked RunKeeper for awhile until I started doing multisport workouts. For some reason, RK cannot properly evaluate the workout on a multisport activity from the Garmin. About 00% of my workouts do not import correctly (either by importing the TCX manually or using the Garmin plugin - the last "lap" of each workout gets cut off). The tool is useless if I can't accurately get data into it. To be fair, it's been a couple of months since I bothered to try because I stopped using it, they may have fixed it. They wouldn't even acknowledge the issue when I reported it though...  Now I just use the Garmin Connect website. Reports aren't as detailed as RK's, but the data is accurate and I like the auto upload of the data from my watch as soon as it gets into bluetooth range of my computer. Before committing to just using GC, Endomondo was my next choice and seems to be the site where a lot of RKs abandoning users migrate to.  I also should add, I'm a triathlete and swims are a regular part of my workouts with my Garmin. No smartphone app can currently meet those needs so feel free to completely disregard everything I've said.  Any suggestions for the best running app for head to head challenges and encouragement with a buddy across the state? We both run with iPhones for music, but use other devices for speed, distance, etc (a Polar RX000 and Timex GPS, respectively). I would prefer to not use Facebook, but will if I have no choice.  Instant notifications of runs and and real time encouragement would be a huge plus. I might even get out of bed and run if I know my buddy just started his run?
