The Beeline is exactly the kind of compass that cyclists need. Having your phone out while you’re on a bicycle ride is dangerous business, even if you’re using it for your GPS. If you have it strapped to your bike and keep looking down at the directions, you could crash pretty hard. If you pull it out of your pocket, one little bump could send it hurdling to the ground. And if you put on headphones to hear the turn-by-turn, they you could miss the sound of oncoming traffic.
