Yeah, this actually demonstrates exactly why I don't use my iPhone as a steps tracker and much prefer the fitbit. I have the 6+ iPhone and it's simply too big for there to be an expectation that I'm going to carry it everywhere I go and therefore have it reliably track all my steps. The fitbit is perfect because I can put it on and forget it and not look like a giant douche while I'm at it, either.
Advantages of being male: I have pretty much that exact ridiculous pouch and I put it on my bicep. Nary a problem, except when MapMyRun decides that those 4 miles were actually zero because herp derp forgot to turn on the GPS. There has to be a fitness tracker that doesn't puke once a week, I just haven't found it yet.

Apropos of nothing, I was once commissioned by a magnet manufacturer to design a dress made of magnets for the PPAI fashion show. PPAI is where manufacturers show their "promotional products" - like pens and mousepads and shit that you can print your company name imprinted on - and they have a "fashion show" to show off wearable products. (Hats, t-shirts, safety vests, etc.) The magnet manufacturer wanted to stand out, so they talked to me about making a dress out of magnets, so their products could be featured in the fashion show. I ballparked the design and building of the dress at around $1500, and they balked at that. I did designs, renderings, drawings, etc, and the dress even transformed... the length could be changed by peeling off the lower skirts (since they were magnetic), the collar could be changed, etc. It would have been a news story EVERYWHERE - not just at the convention - but they were too short-sighted to see the potential and canned the project. Too bad. I would have liked to have seen that dress...
Yeah, I'm with you on this. On my left arm and on my "under-wrist." It just makes sense. I could even type pretty quickly with my right hand. It's ergonomic. Try it now, pretend type on your under-wrist with your right hand. Seems natural, doesn't it? (Left handed people swap out right for left and vice versa)
