I've recently started using the Nike+ app and sensor for tracking my walking/treadmill activity. Unfortunately, it does not work on an elliptical machine, but it's still a lot of fun and I'm doing something good for myself in the process.
The next step is to track my heart rate during exercises, which requires a heart rate monitor (strap) that communicates back to an iPhone app. I think I've exhausted the possibilities of getting any heart rate monitor to communicate back to the Nike+ app, unless I'm willing to purchase a brand new Nano and cut my music catalog down by a tenth, so that isn't happening. So I'm looking at a heart rate monitor that will communicate with a widely used, reliable and/or low cost iPhone 4S app, preferably one that can work at the same time as the Nike+ app that is stock, resident and free on the iPhone and which I use and will continue to use while walking with the Nike+ sensor that gets attached to my shoelaces.
The next step is the heart rate monitor itself (strap). Lots and lots of choices out there but all roads lead toward Wahoo Fitness and their combination ANT+ plug into the base of the iPhone, and the heart rate monitor strap. Looks like I can get them both on Amazon for about $60, which is a lot cheaper than I saw elsewhere. Very expensive line of products. And lots of "hopefullys" - hopefully, it won't drain my battery down on moderate to long walks; hopefully, I can run their app and the Nike+ app at the same time without interfering with one another (they do have a stride sensor but that's just more money that I've already spent on the Nike+ sensor which works fine); and hopefully, the stock strap will fit a 52" - 54" chest (I'm a big guy, they offer no data, they have no contact number, I'd have a drop them a support email and just wait for a response, company reputation for customer service is not good).
So am I looking at the best choice for my needs, or has anyone else recently purchased a similar system for measuring heart rate, stride and/or any other critical components of their exercise routine? I am up for suggestions and not making any purchases so fast.
Last but not least, my current Nike+ app and sensor also work with my old iPod 3G running iOS5, I'm hoping that whatever I wind up with will work on that setup as well.
