Where should I put my phone while recording?

We recommend keeping your phone in an inside pocket of your jacket if you can. If it's really cold it's best not to stick it in an outside pocket, you don't want it to get too cold which can reduce GPS accuracy and battery life.

Just don't put your phone in your backpack. For GPS signal to get through so Slopes can record your day accurately, it needs to be kept somewhere it is not too obstructed.
