Set up your alarm like you usually do on your smart phone.
Place your phone inside the EarlyBirdy box, making sure your charger is inserted in one of the holes.
After locking the box, place your key stand somewhere outside of your room. Popular places include the kitchen next to the coffee machine or the bathroom, next to your toothbrush.
When the alarm goes off in the morning, gently unplug the charger from your phone.
Walk over to where you placed the key stand and unlock the box to turn off your alarm.
