We don't want to have to take our fitness tracker off every time we get in the shower. Sure, not everyone needs to be able to swim with the thing, but every time we see what seems to be a basic band of rubber that still needs to be left on the sink every morning, we sigh.
You have to read the blurb on this subject carefully when buying a fitness tracker. For example, Fitbit used to describe its trackers as waterproof, but has now toned down its wording. If you say something is waterproof, someone on the internet is going to prove that, somehow, it isn't. That seems to be what happened to Fitbit.
Misfit is one company that has held onto its 'completely waterproof' claim, meaning you can not only shower with one of its trackers on, but swim with it too.
Others, like the Moov Now, are picking up the baton as well – this is a trend that has to continue.
