* Most touchscreens do not work well with gloves, in the rain, or with sweaty hands.
* Few smartphones are waterproof, so a specialist case will be required to protect it. (See caveats below regarding cases and GPS Accuracy.)
* The battery life of a smartphone can be an issue. I've found that typically a fully charged phone will only last around 4 hours with the screen active.

There are a number of options for adding heart rate monitoring to a smartphone.
* The phone needs a good view of the sky, so holding it in your hand, or strapping it to your upper arm works well. Clipping it to a waistband can reduce GPS accuracy.
* Close all other applications other than the running application. This does not appear to be a major problem, but it may help slightly.
* Even if your smartphone and your application are accurate, check that the exported data is also accurate, as I've seen some problems in this area.
