The older we get the more we need to pay attention to our bodies to ensure that we are taking the right steps in living happy and healthy lives.  Sometimes monitoring these things is rather difficult or expensive, but thanks to the UK charity RNID, you will be able to east least check your hearing for free using only your iPhone and a set of earbuds. Checking to see if you are hard of hearing with Hearing Check is extremely straightforward.  But before you even launch the app, make sure you have a set of earbuds plugged into your iPhone, otherwise you won’t be able to progress.
