Communicate with 1 touch "shout-ifications"
Arnold does the talking for you. Just tell him what to shout at your friends and his voice will come pouring out of their phone.
Is your friend in a meeting with their boss? Send an Arnold.
Is your friend taking an exam? Send an Arnold.
Is your friend out on a first date? Send an Arnold.
Theres no time when sending an Arnold is not acceptable or encouraged. Shout away.
